41 \class QGraphicsItem -

42 \brief The QGraphicsItem class is the base class for all graphical -

43 items in a QGraphicsScene. -

44 \since 4.2 -

45 -

46 \ingroup graphicsview-api -

47 \inmodule QtWidgets -

48 -

49 It provides a light-weight foundation for writing your own custom items. -

50 This includes defining the item's geometry, collision detection, its -

51 painting implementation and item interaction through its event handlers. -

52 QGraphicsItem is part of the \l{Graphics View Framework} -

53 -

54 \image graphicsview-items.png -

55 -

56 For convenience, Qt provides a set of standard graphics items for the most -

57 common shapes. These are: -

58 -

59 \list -

60 \li QGraphicsEllipseItem provides an ellipse item -

61 \li QGraphicsLineItem provides a line item -

62 \li QGraphicsPathItem provides an arbitrary path item -

63 \li QGraphicsPixmapItem provides a pixmap item -

64 \li QGraphicsPolygonItem provides a polygon item -

65 \li QGraphicsRectItem provides a rectangular item -

66 \li QGraphicsSimpleTextItem provides a simple text label item -

67 \li QGraphicsTextItem provides an advanced text browser item -

68 \endlist -

69 -

70 All of an item's geometric information is based on its local coordinate -

71 system. The item's position, pos(), is the only function that does not -

72 operate in local coordinates, as it returns a position in parent -

73 coordinates. \l {The Graphics View Coordinate System} describes the coordinate -

74 system in detail. -

75 -

76 You can set whether an item should be visible (i.e., drawn, and accepting -

77 events), by calling setVisible(). Hiding an item will also hide its -

78 children. Similarly, you can enable or disable an item by calling -

79 setEnabled(). If you disable an item, all its children will also be -

80 disabled. By default, items are both visible and enabled. To toggle -

81 whether an item is selected or not, first enable selection by setting -

82 the ItemIsSelectable flag, and then call setSelected(). Normally, -

83 selection is toggled by the scene, as a result of user interaction. -

84 -

85 To write your own graphics item, you first create a subclass of -

86 QGraphicsItem, and then start by implementing its two pure virtual public -

87 functions: boundingRect(), which returns an estimate of the area painted -

88 by the item, and paint(), which implements the actual painting. For -

89 example: -

90 -

91 \snippet code/src_gui_graphicsview_qgraphicsitem.cpp 0 -

92 -

93 The boundingRect() function has many different purposes. -

94 QGraphicsScene bases its item index on boundingRect(), and -

95 QGraphicsView uses it both for culling invisible items, and for -

96 determining the area that needs to be recomposed when drawing -

97 overlapping items. In addition, QGraphicsItem's collision -

98 detection mechanisms use boundingRect() to provide an efficient -

99 cut-off. The fine grained collision algorithm in -

100 collidesWithItem() is based on calling shape(), which returns an -

101 accurate outline of the item's shape as a QPainterPath. -

102 -

103 QGraphicsScene expects all items boundingRect() and shape() to -

104 remain unchanged unless it is notified. If you want to change an -

105 item's geometry in any way, you must first call -

106 prepareGeometryChange() to allow QGraphicsScene to update its -

107 bookkeeping. -

108 -

109 Collision detection can be done in two ways: -

110 -

111 \list 1 -

112 -

113 \li Reimplement shape() to return an accurate shape for your item, -

114 and rely on the default implementation of collidesWithItem() to do -

115 shape-shape intersection. This can be rather expensive if the -

116 shapes are complex. -

117 -

118 \li Reimplement collidesWithItem() to provide your own custom item -

119 and shape collision algorithm. -

120 -

121 \endlist -

122 -

123 The contains() function can be called to determine whether the item \e -

124 contains a point or not. This function can also be reimplemented by the -

125 item. The default behavior of contains() is based on calling shape(). -

126 -

127 Items can contain other items, and also be contained by other items. All -

128 items can have a parent item and a list of children. Unless the item has -

129 no parent, its position is in \e parent coordinates (i.e., the parent's -

130 local coordinates). Parent items propagate both their position and their -

131 transformation to all children. -

132 -

133 \image graphicsview-parentchild.png -

134 -

135 \target Transformations -

136 \section1 Transformations -

137 -

138 QGraphicsItem supports projective transformations in addition to its base -

139 position, pos(). There are several ways to change an item's transformation. -

140 For simple transformations, you can call either of the convenience -

141 functions setRotation() or setScale(), or you can pass any transformation -

142 matrix to setTransform(). For advanced transformation control you also have -

143 the option of setting several combined transformations by calling -

144 setTransformations(). -

145 -

146 Item transformations accumulate from parent to child, so if both a parent -

147 and child item are rotated 90 degrees, the child's total transformation -

148 will be 180 degrees. Similarly, if the item's parent is scaled to 2x its -

149 original size, its children will also be twice as large. An item's -

150 transformation does not affect its own local geometry; all geometry -

151 functions (e.g., contains(), update(), and all the mapping functions) still -

152 operate in local coordinates. For convenience, QGraphicsItem provides the -

153 functions sceneTransform(), which returns the item's total transformation -

154 matrix (including its position and all parents' positions and -

155 transformations), and scenePos(), which returns its position in scene -

156 coordinates. To reset an item's matrix, call resetTransform(). -

157 -

158 Certain transformation operations produce a different outcome depending on -

159 the order in which they are applied. For example, if you scale an -

160 transform, and then rotate it, you may get a different result than if the -

161 transform was rotated first. However, the order you set the transformation -

162 properties on QGraphicsItem does not affect the resulting transformation; -

163 QGraphicsItem always applies the properties in a fixed, defined order: -

164 -

165 \list -

166 \li The item's base transform is applied (transform()) -

167 \li The item's transformations list is applied in order (transformations()) -

168 \li The item is rotated relative to its transform origin point (rotation(), transformOriginPoint()) -

169 \li The item is scaled relative to its transform origin point (scale(), transformOriginPoint()) -

170 \endlist -

171 -

172 \section1 Painting -

173 -

174 The paint() function is called by QGraphicsView to paint the item's -

175 contents. The item has no background or default fill of its own; whatever -

176 is behind the item will shine through all areas that are not explicitly -

177 painted in this function. You can call update() to schedule a repaint, -

178 optionally passing the rectangle that needs a repaint. Depending on -

179 whether or not the item is visible in a view, the item may or may not be -

180 repainted; there is no equivalent to QWidget::repaint() in QGraphicsItem. -

181 -

182 Items are painted by the view, starting with the parent items and then -

183 drawing children, in ascending stacking order. You can set an item's -

184 stacking order by calling setZValue(), and test it by calling -

185 zValue(), where items with low z-values are painted before items with -

186 high z-values. Stacking order applies to sibling items; parents are always -

187 drawn before their children. -

188 -

189 \section1 Sorting -

190 -

191 All items are drawn in a defined, stable order, and this same order decides -

192 which items will receive mouse input first when you click on the scene. -

193 Normally you don't have to worry about sorting, as the items follow a -

194 "natural order", following the logical structure of the scene. -

195 -

196 An item's children are stacked on top of the parent, and sibling items are -

197 stacked by insertion order (i.e., in the same order that they were either -

198 added to the scene, or added to the same parent). If you add item A, and -

199 then B, then B will be on top of A. If you then add C, the items' stacking -

200 order will be A, then B, then C. -

201 -

202 \image graphicsview-zorder.png -

203 -

204 This example shows the stacking order of all limbs of the robot from the -

205 \l{graphicsview/dragdroprobot}{Drag and Drop Robot} example. The torso is -

206 the root item (all other items are children or descendants of the torso), -

207 so it is drawn first. Next, the head is drawn, as it is the first item in -

208 the torso's list of children. Then the upper left arm is drawn. As the -

209 lower arm is a child of the upper arm, the lower arm is then drawn, -

210 followed by the upper arm's next sibling, which is the upper right arm, and -

211 so on. -

212 -

213 For advanced users, there are ways to alter how your items are sorted: -

214 -

215 \list -

216 \li You can call setZValue() on an item to explicitly stack it on top of, or -

217 under, other sibling items. The default Z value for an item is 0. Items -

218 with the same Z value are stacked by insertion order. -

219 -

220 \li You can call stackBefore() to reorder the list of children. This will -

221 directly modify the insertion order. -

222 -

223 \li You can set the ItemStacksBehindParent flag to stack a child item behind -

224 its parent. -

225 \endlist -

226 -

227 The stacking order of two sibling items also counts for each item's -

228 children and descendant items. So if one item is on top of another, then -

229 all its children will also be on top of all the other item's children as -

230 well. -

231 -

232 \section1 Events -

233 -

234 QGraphicsItem receives events from QGraphicsScene through the virtual -

235 function sceneEvent(). This function distributes the most common events -

236 to a set of convenience event handlers: -

237 -

238 \list -

239 \li contextMenuEvent() handles context menu events -

240 \li focusInEvent() and focusOutEvent() handle focus in and out events -

241 \li hoverEnterEvent(), hoverMoveEvent(), and hoverLeaveEvent() handles -

242 hover enter, move and leave events -

243 \li inputMethodEvent() handles input events, for accessibility support -

244 \li keyPressEvent() and keyReleaseEvent() handle key press and release events -

245 \li mousePressEvent(), mouseMoveEvent(), mouseReleaseEvent(), and -

246 mouseDoubleClickEvent() handles mouse press, move, release, click and -

247 doubleclick events -

248 \endlist -

249 -

250 You can filter events for any other item by installing event filters. This -

251 functionality is separate from Qt's regular event filters (see -

252 QObject::installEventFilter()), which only work on subclasses of QObject. After -

253 installing your item as an event filter for another item by calling -

254 installSceneEventFilter(), the filtered events will be received by the virtual -

255 function sceneEventFilter(). You can remove item event filters by calling -

256 removeSceneEventFilter(). -

257 -

258 \section1 Custom Data -

259 -

260 Sometimes it's useful to register custom data with an item, be it a custom -

261 item, or a standard item. You can call setData() on any item to store data -

262 in it using a key-value pair (the key being an integer, and the value is a -

263 QVariant). To get custom data from an item, call data(). This -

264 functionality is completely untouched by Qt itself; it is provided for the -

265 user's convenience. -

266 -

267 \sa QGraphicsScene, QGraphicsView, {Graphics View Framework} -

268 */ -

269 -

270 /*! -

271 \variable QGraphicsItem::Type -

272 -

273 The type value returned by the virtual type() function in standard -

274 graphics item classes in Qt. All such standard graphics item -

275 classes in Qt are associated with a unique value for Type, -

276 e.g. the value returned by QGraphicsPathItem::type() is 2. -

277 -

279 */ -

280 -

281 /*! -

282 \variable QGraphicsItem::UserType -

283 -

284 The lowest permitted type value for custom items (subclasses -

285 of QGraphicsItem or any of the standard items). This value is -

286 used in conjunction with a reimplementation of QGraphicsItem::type() -

287 and declaring a Type enum value. Example: -

288 -

289 \snippet code/src_gui_graphicsview_qgraphicsitem.cpp 1 -

290 -

291 \note UserType = 65536 -

292 */ -

293 -

294 /*! -

295 \enum QGraphicsItem::GraphicsItemFlag -

296 -

297 This enum describes different flags that you can set on an item to -

298 toggle different features in the item's behavior. -

299 -

300 All flags are disabled by default. -

301 -

302 \value ItemIsMovable The item supports interactive movement using -

303 the mouse. By clicking on the item and then dragging, the item -

304 will move together with the mouse cursor. If the item has -

305 children, all children are also moved. If the item is part of a -

306 selection, all selected items are also moved. This feature is -

307 provided as a convenience through the base implementation of -

308 QGraphicsItem's mouse event handlers. -

309 -

310 \value ItemIsSelectable The item supports selection. Enabling this -

311 feature will enable setSelected() to toggle selection for the -

312 item. It will also let the item be selected automatically as a -

313 result of calling QGraphicsScene::setSelectionArea(), by clicking -

314 on an item, or by using rubber band selection in QGraphicsView. -

315 -

316 \value ItemIsFocusable The item supports keyboard input focus (i.e., it is -

317 an input item). Enabling this flag will allow the item to accept focus, -

318 which again allows the delivery of key events to -

319 QGraphicsItem::keyPressEvent() and QGraphicsItem::keyReleaseEvent(). -

320 -

321 \value ItemClipsToShape The item clips to its own shape. The item cannot -

322 draw or receive mouse, tablet, drag and drop or hover events outside its -

323 shape. It is disabled by default. This behavior is enforced by -

324 QGraphicsView::drawItems() or QGraphicsScene::drawItems(). This flag was -

325 introduced in Qt 4.3. -

326 -

327 \value ItemClipsChildrenToShape The item clips the painting of all its -

328 descendants to its own shape. Items that are either direct or indirect -

329 children of this item cannot draw outside this item's shape. By default, -

330 this flag is disabled; children can draw anywhere. This behavior is -

331 enforced by QGraphicsView::drawItems() or -

332 QGraphicsScene::drawItems(). This flag was introduced in Qt 4.3. -

333 \note This flag is similar to ItemContainsChildrenInShape but in addition -

334 enforces the containment by clipping the children. -

335 -

336 \value ItemIgnoresTransformations The item ignores inherited -

337 transformations (i.e., its position is still anchored to its parent, but -

338 the parent or view rotation, zoom or shear transformations are ignored). -

339 This flag is useful for keeping text label items horizontal and unscaled, -

340 so they will still be readable if the view is transformed. When set, the -

341 item's view geometry and scene geometry will be maintained separately. You -

342 must call deviceTransform() to map coordinates and detect collisions in -

343 the view. By default, this flag is disabled. This flag was introduced in -

344 Qt 4.3. \note With this flag set you can still scale the item itself, and -

345 that scale transformation will influence the item's children. -

346 -

347 \value ItemIgnoresParentOpacity The item ignores its parent's opacity. The -

348 item's effective opacity is the same as its own; it does not combine with -

349 the parent's opacity. This flags allows your item to keep its absolute -

350 opacity even if the parent is semitransparent. This flag was introduced in -

351 Qt 4.5. -

352 -

353 \value ItemDoesntPropagateOpacityToChildren The item doesn't propagate its -

354 opacity to its children. This flag allows you to create a semitransparent -

355 item that does not affect the opacity of its children. This flag was -

356 introduced in Qt 4.5. -

357 -

358 \value ItemStacksBehindParent The item is stacked behind its parent. By -

359 default, child items are stacked on top of the parent item. But setting -

360 this flag, the child will be stacked behind it. This flag is useful for -

361 drop shadow effects and for decoration objects that follow the parent -

362 item's geometry without drawing on top of it. This flag was introduced -

363 in Qt 4.5. -

364 -

365 \value ItemUsesExtendedStyleOption The item makes use of either -

366 \l{QStyleOptionGraphicsItem::} {exposedRect} or -

367 \l{QStyleOptionGraphicsItem::} {matrix} in -

368 QStyleOptionGraphicsItem. By default, the -

369 \l{QStyleOptionGraphicsItem::} {exposedRect} is initialized to the -

370 item's boundingRect() and the -

371 \l{QStyleOptionGraphicsItem::}{matrix} is untransformed. You can -

372 enable this flag for the style options to be set up with more -

373 fine-grained values. Note that -

374 QStyleOptionGraphicsItem::levelOfDetail is unaffected by this flag -

375 and always initialized to 1. Use -

376 QStyleOptionGraphicsItem::levelOfDetailFromTransform() if you need -

377 a higher value. This flag was introduced in Qt 4.6. -

378 -

379 \value ItemHasNoContents The item does not paint anything (i.e., calling -

380 paint() on the item has no effect). You should set this flag on items that -

381 do not need to be painted to ensure that Graphics View avoids unnecessary -

382 painting preparations. This flag was introduced in Qt 4.6. -

383 -

384 \value ItemSendsGeometryChanges The item enables itemChange() -

385 notifications for ItemPositionChange, ItemPositionHasChanged, -

386 ItemMatrixChange, ItemTransformChange, ItemTransformHasChanged, -

387 ItemRotationChange, ItemRotationHasChanged, ItemScaleChange, ItemScaleHasChanged, -

388 ItemTransformOriginPointChange, and ItemTransformOriginPointHasChanged. For -

389 performance reasons, these notifications are disabled by default. You must -

390 enable this flag to receive notifications for position and transform -

391 changes. This flag was introduced in Qt 4.6. -

392 -

393 \value ItemAcceptsInputMethod The item supports input methods typically -

394 used for Asian languages. -

395 This flag was introduced in Qt 4.6. -

396 -

397 \value ItemNegativeZStacksBehindParent The item automatically -

398 stacks behind it's parent if it's z-value is negative. This flag -

399 enables setZValue() to toggle ItemStacksBehindParent. This flag -

400 was introduced in Qt 4.6. -

401 -

402 \value ItemIsPanel The item is a panel. A panel provides activation and -

403 contained focus handling. Only one panel can be active at a time (see -

404 QGraphicsItem::isActive()). When no panel is active, QGraphicsScene -

405 activates all non-panel items. Window items (i.e., -

406 QGraphicsItem::isWindow() returns \c true) are panels. This flag was -

407 introduced in Qt 4.6. -

408 -

409 \omitvalue ItemIsFocusScope \omit Internal only (for now). \endomit -

410 -

411 \value ItemSendsScenePositionChanges The item enables itemChange() -

412 notifications for ItemScenePositionHasChanged. For performance reasons, -

413 these notifications are disabled by default. You must enable this flag -

414 to receive notifications for scene position changes. This flag was -

415 introduced in Qt 4.6. -

416 -

417 \omitvalue ItemStopsClickFocusPropagation \omit The item stops propagating -

418 click focus to items underneath when being clicked on. This flag -

419 allows you create a non-focusable item that can be clicked on without -

420 changing the focus. \endomit -

421 -

422 \omitvalue ItemStopsFocusHandling \omit Same as -

423 ItemStopsClickFocusPropagation, but also suppresses focus-out. This flag -

424 allows you to completely take over focus handling. -

425 This flag was introduced in Qt 4.7. \endomit -

426 -

427 \value ItemContainsChildrenInShape This flag indicates that all of the -

428 item's direct or indirect children only draw within the item's shape. -

429 Unlike ItemClipsChildrenToShape, this restriction is not enforced. Set -

430 ItemContainsChildrenInShape when you manually assure that drawing -

431 is bound to the item's shape and want to avoid the cost associated with -

432 enforcing the clip. Setting this flag enables more efficient drawing and -

433 collision detection. The flag is disabled by default. -

434 \note If both this flag and ItemClipsChildrenToShape are set, the clip -

435 will be enforced. This is equivalent to just setting -

436 ItemClipsChildrenToShape. -

437 -

438 This flag was introduced in Qt 5.4. -

439 */ -

440 -

441 /*! -

442 \enum QGraphicsItem::GraphicsItemChange -

443 -

444 This enum describes the state changes that are notified by -

445 QGraphicsItem::itemChange(). The notifications are sent as the state -

446 changes, and in some cases, adjustments can be made (see the documentation -

447 for each change for details). -

448 -

449 Note: Be careful with calling functions on the QGraphicsItem itself inside -

450 itemChange(), as certain function calls can lead to unwanted -

451 recursion. For example, you cannot call setPos() in itemChange() on an -

452 ItemPositionChange notification, as the setPos() function will again call -

453 itemChange(ItemPositionChange). Instead, you can return the new, adjusted -

454 position from itemChange(). -

455 -

456 \value ItemEnabledChange The item's enabled state changes. If the item is -

457 presently enabled, it will become disabled, and vice verca. The value -

458 argument is the new enabled state (i.e., true or false). Do not call -

459 setEnabled() in itemChange() as this notification is delivered. Instead, -

460 you can return the new state from itemChange(). -

461 -

462 \value ItemEnabledHasChanged The item's enabled state has changed. The -

463 value argument is the new enabled state (i.e., true or false). Do not call -

464 setEnabled() in itemChange() as this notification is delivered. The return -

465 value is ignored. -

466 -

467 \value ItemMatrixChange The item's affine transformation matrix is -

468 changing. This value is obsolete; you can use ItemTransformChange instead. -

469 -

470 \value ItemPositionChange The item's position changes. This notification -

471 is sent if the ItemSendsGeometryChanges flag is enabled, and when the -

472 item's local position changes, relative to its parent (i.e., as a result -

473 of calling setPos() or moveBy()). The value argument is the new position -

474 (i.e., a QPointF). You can call pos() to get the original position. Do -

475 not call setPos() or moveBy() in itemChange() as this notification is -

476 delivered; instead, you can return the new, adjusted position from -

477 itemChange(). After this notification, QGraphicsItem immediately sends the -

478 ItemPositionHasChanged notification if the position changed. -

479 -

480 \value ItemPositionHasChanged The item's position has changed. This -

481 notification is sent if the ItemSendsGeometryChanges flag is enabled, and -

482 after the item's local position, relative to its parent, has changed. The -

483 value argument is the new position (the same as pos()), and QGraphicsItem -

490 calling setTransform(). The value argument is the new matrix (i.e., a -

491 QTransform); to get the old matrix, call transform(). Do not call -

492 setTransform() or set any of the transformation properties in itemChange() -

493 as this notification is delivered; instead, you can return the new matrix -

494 from itemChange(). This notification is not sent if you change the -

495 transformation properties. -

496 -

497 \value ItemTransformHasChanged The item's transformation matrix has -

498 changed either because setTransform is called, or one of the -

499 transformation properties is changed. This notification is sent if the -

585 pass this item to any item's setParentItem() function as this notification -

586 is delivered. The return value is unused; you cannot adjust anything in -

587 this notification. Note that the new child might not be fully constructed -

588 when this notification is sent; calling pure virtual functions on -

589 the child can lead to a crash. -

597 also sent when the item is added to its initial scene, and when it is removed. -

598 The item's scene() is the old scene (or 0 if the item has not been added to a -

599 scene yet). The value argument is the new scene (i.e., a QGraphicsScene -

600 pointer), or a null pointer if the item is removed from a scene. Do not -

601 override this change by passing this item to QGraphicsScene::addItem() as this -

602 notification is delivered; instead, you can return the new scene from -

603 itemChange(). Use this feature with caution; objecting to a scene change can -

604 quickly lead to unwanted recursion. -

605 -

606 \value ItemSceneHasChanged The item's scene has changed. The item's scene() is -

607 the new scene. This notification is also sent when the item is added to its -

659 This notification is sent if the ItemSendsScenePositionChanges flag is -

660 enabled, and after the item's scene position has changed (i.e., the -

661 position or transformation of the item itself or the position or -

662 transformation of any ancestor has changed). The value argument is the -

663 new scene position (the same as scenePos()), and QGraphicsItem ignores -

664 the return value for this notification (i.e., a read-only notification). -

668 \enum QGraphicsItem::CacheMode -

669 \since 4.4 -

670 -

671 This enum describes QGraphicsItem's cache modes. Caching is used to speed -

672 up rendering by allocating and rendering to an off-screen pixel buffer, -

673 which can be reused when the item requires redrawing. For some paint -

674 devices, the cache is stored directly in graphics memory, which makes -

675 rendering very quick. -

676 -

677 \value NoCache The default; all item caching is -

678 disabled. QGraphicsItem::paint() is called every time the item needs -

679 redrawing. -

680 -

681 \value ItemCoordinateCache Caching is enabled for the item's logical -

682 (local) coordinate system. QGraphicsItem creates an off-screen pixel -

683 buffer with a configurable size / resolution that you can pass to -

684 QGraphicsItem::setCacheMode(). Rendering quality will typically degrade, -

685 depending on the resolution of the cache and the item transformation. The -

686 first time the item is redrawn, it will render itself into the cache, and -

687 the cache is then reused for every subsequent expose. The cache is also -

688 reused as the item is transformed. To adjust the resolution of the cache, -

689 you can call setCacheMode() again. -

690 -

691 \value DeviceCoordinateCache Caching is enabled at the paint device level, -

692 in device coordinates. This mode is for items that can move, but are not -

693 rotated, scaled or sheared. If the item is transformed directly or -

694 indirectly, the cache will be regenerated automatically. Unlike -

695 ItemCoordinateCacheMode, DeviceCoordinateCache always renders at maximum -

696 quality. -

2041 \since 4.4 -

2042 Sets the item's cache mode to \a mode. -

2043 -

2044 The optional \a logicalCacheSize argument is used only by -

2045 ItemCoordinateCache mode, and describes the resolution of the cache -

2046 buffer; if \a logicalCacheSize is (100, 100), QGraphicsItem will fit the -

2047 item into 100x100 pixels in graphics memory, regardless of the logical -

2048 size of the item itself. By default QGraphicsItem uses the size of -

2049 boundingRect(). For all other cache modes than ItemCoordinateCache, \a -

2050 logicalCacheSize is ignored. -

2051 -

2052 Caching can speed up rendering if your item spends a significant time -

2053 redrawing itself. In some cases the cache can also slow down rendering, in -

2054 particular when the item spends less time redrawing than QGraphicsItem -

2055 spends redrawing from the cache. -

2056 -

2057 When caching is enabled, an item's paint() function will generally draw into an -

2058 offscreen pixmap cache; for any subsequent -

2059 repaint requests, the Graphics View framework will redraw from the -

2060 cache. This approach works particularly well with QGLWidget, which stores -

2061 all the cache as OpenGL textures. -

2062 -

2063 Be aware that QPixmapCache's cache limit may need to be changed to obtain -

2064 optimal performance. -

2065 -

2066 You can read more about the different cache modes in the CacheMode -

2067 documentation. -

2068 -

2069 \note Enabling caching does not imply that the item's paint() function will be -

2070 called only in response to an explicit update() call. For instance, under -

2071 memory pressure, Qt may decide to drop some of the cache information; -

2072 in such cases an item's paint() function will be called even if there -

2073 was no update() call (that is, exactly as if there were no caching enabled). -

2513 If \a visible is true, the item is made visible. Otherwise, the item is -

2514 made invisible. Invisible items are not painted, nor do they receive any -

2515 events. In particular, mouse events pass right through invisible items, -

2516 and are delivered to any item that may be behind. Invisible items are also -

2517 unselectable, they cannot take input focus, and are not detected by -

2518 QGraphicsScene's item location functions. -

2519 -

2520 If an item becomes invisible while grabbing the mouse, (i.e., while it is -

2521 receiving mouse events,) it will automatically lose the mouse grab, and -

2522 the grab is not regained by making the item visible again; it must receive -

2523 a new mouse press to regain the mouse grab. -

2794 (opaque). The item's local opacity is combined with parent and ancestor -

2795 opacities into the effectiveOpacity(). -

2797 By default, opacity propagates from parent to child, so if a parent's -

2798 opacity is 0.5 and the child is also 0.5, the child's effective opacity -

2799 will be 0.25. -

2801 The opacity property decides the state of the painter passed to the -

2802 paint() function. If the item is cached, i.e., ItemCoordinateCache or -

2803 DeviceCoordinateCache, the effective property will be applied to the -

2804 item's cache as it is rendered. -

3654 following events occur: -

3655 -

3656 \list -

3657 \li The item becomes invisible -

3658 \li The item is removed from the scene -

3665 When an item gains the keyboard grab, it receives a QEvent::GrabKeyboard -

3666 event. When it loses the keyboard grab, it receives a -

3667 QEvent::UngrabKeyboard event. These events can be used to detect when your -

3668 item gains or loses the keyboard grab through other means than gaining -

3669 input focus. -

3670 -

3671 It is almost never necessary to explicitly grab the keyboard in Qt, as Qt -

3672 grabs and releases it sensibly. In particular, Qt grabs the keyboard when -

3673 your item gains input focus, and releases it when your item loses input -

3674 focus, or when the item is hidden. -

3675 -

3676 Note that only visible items can grab keyboard input. Calling -

3677 grabKeyboard() on an invisible item has no effect. -

4881 This pure virtual function defines the outer bounds of the item as -

4883 bounding rect. QGraphicsView uses this to determine whether the -

4890 If you want to change the item's bounding rectangle, you must first call -

4891 prepareGeometryChange(). This notifies the scene of the imminent change, -

4892 so that it can update its item geometry index; otherwise, the scene will -

4893 be unaware of the item's new geometry, and the results are undefined -

5419 -

5420 This function, which is usually called by QGraphicsView, paints the -

5421 contents of an item in local coordinates. -

5422 -

5423 Reimplement this function in a QGraphicsItem subclass to provide the -

5424 item's painting implementation, using \a painter. The \a option parameter -

5425 provides style options for the item, such as its state, exposed area and -

5426 its level-of-detail hints. The \a widget argument is optional. If -

5427 provided, it points to the widget that is being painted on; otherwise, it -

5428 is 0. For cached painting, \a widget is always 0. -

5429 -

5430 \snippet code/src_gui_graphicsview_qgraphicsitem.cpp 10 -

5431 -

5432 The painter's pen is 0-width by default, and its pen is initialized to the -

5433 QPalette::Text brush from the paint device's palette. The brush is -

5434 initialized to QPalette::Window. -

5435 -

5436 Make sure to constrain all painting inside the boundaries of -

5437 boundingRect() to avoid rendering artifacts (as QGraphicsView does not -

5438 clip the painter for you). In particular, when QPainter renders the -

5439 outline of a shape using an assigned QPen, half of the outline will be -

5440 drawn outside, and half inside, the shape you're rendering (e.g., with a -

5441 pen width of 2 units, you must draw outlines 1 unit inside -

5442 boundingRect()). QGraphicsItem does not support use of cosmetic pens with -

5443 a non-zero width. -

5444 -

5445 All painting is done in local coordinates. -

5446 -

5447 \note It is mandatory that an item will always redraw itself in the exact -

5448 same way, unless update() was called; otherwise visual artifacts may -

5449 occur. In other words, two subsequent calls to paint() must always produce -

5450 the same output, unless update() was called between them. -

5451 -

5452 \note Enabling caching for an item does not guarantee that paint() -

5453 will be invoked only once by the Graphics View framework, -

5454 even without any explicit call to update(). See the documentation of -

5455 setCacheMode() for more details. -

5829 (the default), the item's bounding rect is scrolled. -

5830 -

5831 Scrolling provides a fast alternative to simply redrawing when the -

5832 contents of the item (or parts of the item) are shifted vertically or -

5833 horizontally. Depending on the current transformation and the capabilities -

5834 of the paint device (i.e., the viewport), this operation may consist of -

5835 simply moving pixels from one location to another using memmove(). In most -

5836 cases this is faster than rerendering the entire area. -

5837 -

5838 After scrolling, the item will issue an update for the newly exposed -

5839 areas. If scrolling is not supported (e.g., you are rendering to an OpenGL -

5840 viewport, which does not benefit from scroll optimizations), this function -

5841 is equivalent to calling update(\a rect). -

5845 update(\a rect). If you for sure know that the item is opaque and not overlapped -

5846 by other items, you can map the \a rect to viewport coordinates and scroll the -

7721 \class QGraphicsObject -

7722 \brief The QGraphicsObject class provides a base class for all graphics items that -

7723 require signals, slots and properties. -

7724 \since 4.6 -

7725 \ingroup graphicsview-api -

7726 \inmodule QtWidgets -

7727 -

7728 The class extends a QGraphicsItem with QObject's signal/slot and property mechanisms. -

7729 It maps many of QGraphicsItem's basic setters and getters to properties and adds notification -

7730 signals for many of them. -

7731 -

7732 \section1 Parents and Children -

7733 -

7734 Each graphics object can be constructed with a parent item. This ensures that the -

7735 item will be destroyed when its parent item is destroyed. Although QGraphicsObject -

7736 inherits from both QObject and QGraphicsItem, you should use the functions provided -

7737 by QGraphicsItem, \e not QObject, to manage the relationships between parent and -

7738 child items. -

7739 -

7740 The relationships between items can be explored using the parentItem() and childItems() -

7741 functions. In the hierarchy of items in a scene, the parentObject() and parentWidget() -

7742 functions are the equivalent of the QWidget::parent() and QWidget::parentWidget() -

7743 functions for QWidget subclasses. -

8501 \image graphicsview-rectitem.png -

8503 QGraphicsRectItem uses the rectangle and the pen width to provide -

8504 a reasonable implementation of boundingRect(), shape(), and -

8505 contains(). The paint() function draws the rectangle using the -

8506 item's associated pen and brush, which you can set by calling the -

8507 setPen() and setBrush() functions. -

8510 widths or heights, is undefined. If you cannot be sure that you are -

8511 using valid rectangles (for example, if you are creating -

8512 rectangles using data from an unreliable source) then you should -

8513 use QRectF::normalized() to create normalized rectangles, and use -

8514 those instead. -

9494 \class QGraphicsPixmapItem -

9495 \brief The QGraphicsPixmapItem class provides a pixmap item that you can add to -

9496 a QGraphicsScene. -

9497 \since 4.2 -

9498 \ingroup graphicsview-api -

9499 \inmodule QtWidgets -

9500 -

9501 To set the item's pixmap, pass a QPixmap to QGraphicsPixmapItem's -

9502 constructor, or call the setPixmap() function. The pixmap() -

9503 function returns the current pixmap. -

9504 -

9505 QGraphicsPixmapItem uses pixmap's optional alpha mask to provide a -

9506 reasonable implementation of boundingRect(), shape(), and contains(). -

9507 -

9508 \image graphicsview-pixmapitem.png -

9509 -

9510 The pixmap is drawn at the item's (0, 0) coordinate, as returned by -

9511 offset(). You can change the drawing offset by calling setOffset(). -

9512 -

9513 You can set the pixmap's transformation mode by calling -

9514 setTransformationMode(). By default, Qt::FastTransformation is used, which -

9515 provides fast, non-smooth scaling. Qt::SmoothTransformation enables -

9516 QPainter::SmoothPixmapTransform on the painter, and the quality depends on -

9517 the platform and viewport. The result is usually not as good as calling -

9518 QPixmap::scale() directly. Call transformationMode() to get the current -

9519 transformation mode for the item. -

9529 This enum describes how QGraphicsPixmapItem calculates its shape and -

9530 opaque area. -

9531 -

9532 The default value is MaskShape. -

9533 -

9534 \value MaskShape The shape is determined by calling QPixmap::mask(). -

9535 This shape includes only the opaque pixels of the pixmap. -

9536 Because the shape is more complex, however, it can be slower than the other modes, -

9537 and uses more memory. -

9538 -

9539 \value BoundingRectShape The shape is determined by tracing the outline of -

9540 the pixmap. This is the fastest shape mode, but it does not take into account -

9541 any transparent areas on the pixmap. -

9542 -

9543 \value HeuristicMaskShape The shape is determine by calling -

9544 QPixmap::createHeuristicMask(). The performance and memory consumption -

9545 is similar to MaskShape. -

10763 \class QGraphicsSimpleTextItem -

10764 \brief The QGraphicsSimpleTextItem class provides a simple text path item -

10765 that you can add to a QGraphicsScene. -

10766 \since 4.2 -

10767 \ingroup graphicsview-api -

10768 \inmodule QtWidgets -

10769 -

10770 To set the item's text, you can either pass a QString to -

10771 QGraphicsSimpleTextItem's constructor, or call setText() to change the -

10772 text later. To set the text fill color, call setBrush(). -

10773 -

10774 The simple text item can have both a fill and an outline; setBrush() will -

10775 set the text fill (i.e., text color), and setPen() sets the pen that will -

10776 be used to draw the text outline. (The latter can be slow, especially for -

10777 complex pens, and items with long text content.) If all you want is to -

10778 draw a simple line of text, you should call setBrush() only, and leave the -

10779 pen unset; QGraphicsSimpleTextItem's pen is by default Qt::NoPen. -

10780 -

10781 QGraphicsSimpleTextItem uses the text's formatted size and the associated -

10782 font to provide a reasonable implementation of boundingRect(), shape(), -

10783 and contains(). You can set the font by calling setFont(). -

10784 -

10785 QGraphicsSimpleText does not display rich text; instead, you can use -

10786 QGraphicsTextItem, which provides full text control capabilities. -

10987 \class QGraphicsItemGroup -

10988 \brief The QGraphicsItemGroup class provides a container that treats -

10989 a group of items as a single item. -

10990 \since 4.2 -

10991 \ingroup graphicsview-api -

10992 \inmodule QtWidgets -

10993 -

10994 A QGraphicsItemGroup is a special type of compound item that -

10995 treats itself and all its children as one item (i.e., all events -

10996 and geometries for all children are merged together). It's common -

10997 to use item groups in presentation tools, when the user wants to -

10998 group several smaller items into one big item in order to simplify -

10999 moving and copying of items. -

11000 -

11001 If all you want is to store items inside other items, you can use -

11002 any QGraphicsItem directly by passing a suitable parent to -

11003 setParentItem(). -

11004 -

11005 The boundingRect() function of QGraphicsItemGroup returns the -

11006 bounding rectangle of all items in the item group. -

11007 QGraphicsItemGroup ignores the ItemIgnoresTransformations flag on -

11008 its children (i.e., with respect to the geometry of the group -

11009 item, the children are treated as if they were transformable). -

11010 -

11011 There are two ways to construct an item group. The easiest and -

11012 most common approach is to pass a list of items (e.g., all -

11013 selected items) to QGraphicsScene::createItemGroup(), which -

11014 returns a new QGraphicsItemGroup item. The other approach is to -

11015 manually construct a QGraphicsItemGroup item, add it to the scene -

11016 calling QGraphicsScene::addItem(), and then add items to the group -

11017 manually, one at a time by calling addToGroup(). To dismantle -

11018 ("ungroup") an item group, you can either call -

11019 QGraphicsScene::destroyItemGroup(), or you can manually remove all -

11020 items from the group by calling removeFromGroup(). -

11021 -

11022 \snippet code/src_gui_graphicsview_qgraphicsitem.cpp 17 -

11023 -

11024 The operation of adding and removing items preserves the items' -

11025 scene-relative position and transformation, as opposed to calling -

11026 setParentItem(), where only the child item's parent-relative -

11027 position and transformation are kept. -

11028 -

11029 The addtoGroup() function reparents the target item to this item -

11030 group, keeping the item's position and transformation intact -

11031 relative to the scene. Visually, this means that items added via -

11032 addToGroup() will remain completely unchanged as a result of this -

11033 operation, regardless of the item or the group's current position -

11034 or transformation; although the item's position and matrix are -

11035 likely to change. -

11036 -

11037 The removeFromGroup() function has similar semantics to -

11038 setParentItem(); it reparents the item to the parent item of the -

11039 item group. As with addToGroup(), the item's scene-relative -

11040 position and transformation remain intact. -
