235 \class QAbstractItemView-
236-
237 \brief The QAbstractItemView class provides the basic functionality for-
238 item view classes.-
239-
240 \ingroup model-view-
241 \inmodule QtWidgets-
242-
243 QAbstractItemView class is the base class for every standard view-
244 that uses a QAbstractItemModel. QAbstractItemView is an abstract-
245 class and cannot itself be instantiated. It provides a standard-
246 interface for interoperating with models through the signals and-
247 slots mechanism, enabling subclasses to be kept up-to-date with-
248 changes to their models. This class provides standard support for-
249 keyboard and mouse navigation, viewport scrolling, item editing,-
250 and selections. The keyboard navigation implements this-
251 functionality:-
252-
253 \table-
254 \header-
255 \li Keys-
256 \li Functionality-
257 \row-
258 \li Arrow keys-
259 \li Changes the current item and selects it.-
260 \row-
261 \li Ctrl+Arrow keys-
262 \li Changes the current item but does not select it.-
263 \row-
264 \li Shift+Arrow keys-
265 \li Changes the current item and selects it. The previously-
266 selected item(s) is not deselected.-
267 \row-
268 \li Ctr+Space-
269 \li Toggles selection of the current item.-
270 \row-
271 \li Tab/Backtab-
272 \li Changes the current item to the next/previous item.-
273 \row-
274 \li Home/End-
275 \li Selects the first/last item in the model.-
276 \row-
277 \li Page up/Page down-
278 \li Scrolls the rows shown up/down by the number of-
279 visible rows in the view.-
280 \row-
281 \li Ctrl+A-
282 \li Selects all items in the model.-
283 \endtable-
284-
285 Note that the above table assumes that the-
286 \l{selectionMode}{selection mode} allows the operations. For-
287 instance, you cannot select items if the selection mode is-
288 QAbstractItemView::NoSelection.-
289-
290 The QAbstractItemView class is one of the \l{Model/View Classes}-
291 and is part of Qt's \l{Model/View Programming}{model/view framework}.-
292-
293 The view classes that inherit QAbstractItemView only need-
294 to implement their own view-specific functionality, such as-
295 drawing items, returning the geometry of items, finding items,-
296 etc.-
297-
298 QAbstractItemView provides common slots such as edit() and-
299 setCurrentIndex(). Many protected slots are also provided, including-
300 dataChanged(), rowsInserted(), rowsAboutToBeRemoved(), selectionChanged(),-
301 and currentChanged().-
302-
303 The root item is returned by rootIndex(), and the current item by-
304 currentIndex(). To make sure that an item is visible use-
305 scrollTo().-
306-
307 Some of QAbstractItemView's functions are concerned with-
308 scrolling, for example setHorizontalScrollMode() and-
309 setVerticalScrollMode(). To set the range of the scroll bars, you-
310 can, for example, reimplement the view's resizeEvent() function:-
311-
312 \snippet code/src_gui_itemviews_qabstractitemview.cpp 0-
313-
314 Note that the range is not updated until the widget is shown.-
315-
316 Several other functions are concerned with selection control; for-
317 example setSelectionMode(), and setSelectionBehavior(). This class-
318 provides a default selection model to work with-
319 (selectionModel()), but this can be replaced by using-
320 setSelectionModel() with an instance of QItemSelectionModel.-
321-
322 For complete control over the display and editing of items you can-
323 specify a delegate with setItemDelegate().-
324-
325 QAbstractItemView provides a lot of protected functions. Some are-
326 concerned with editing, for example, edit(), and commitData(),-
327 whilst others are keyboard and mouse event handlers.-
328-
329 \note If you inherit QAbstractItemView and intend to update the contents-
330 of the viewport, you should use viewport->update() instead of-
331 \l{QWidget::update()}{update()} as all painting operations take place on the-
332 viewport.-

340 This enum indicates how the view responds to user selections:-
341-
342 \value SingleSelection When the user selects an item, any already-selected-
343 item becomes unselected, and the user cannot unselect the selected item by-
344 clicking on it.-
345-
346 \value ContiguousSelection When the user selects an item in the usual way,-
347 the selection is cleared and the new item selected. However, if the user-
348 presses the Shift key while clicking on an item, all items between the-
349 current item and the clicked item are selected or unselected, depending on-
350 the state of the clicked item.-
351-
352 \value ExtendedSelection When the user selects an item in the usual way,-
353 the selection is cleared and the new item selected. However, if the user-
354 presses the Ctrl key when clicking on an item, the clicked item gets-
355 toggled and all other items are left untouched. If the user presses the-
356 Shift key while clicking on an item, all items between the current item-
357 and the clicked item are selected or unselected, depending on the state of-
358 the clicked item. Multiple items can be selected by dragging the mouse over-
359 them.-
360-
361 \value MultiSelection When the user selects an item in the usual way, the-
362 selection status of that item is toggled and the other items are left-
363 alone. Multiple items can be toggled by dragging the mouse over them.-
364-
365 \value NoSelection Items cannot be selected.-
