241 \class QTabBar-
242 \brief The QTabBar class provides a tab bar, e.g. for use in tabbed dialogs.-
243-
244 \ingroup basicwidgets-
245 \inmodule QtWidgets-
246-
247 QTabBar is straightforward to use; it draws the tabs using one of-
248 the predefined \l{QTabBar::Shape}{shapes}, and emits a-
249 signal when a tab is selected. It can be subclassed to tailor the-
250 look and feel. Qt also provides a ready-made \l{QTabWidget}.-
251-
252 Each tab has a tabText(), an optional tabIcon(), an optional-
253 tabToolTip(), optional tabWhatsThis() and optional tabData().-
254 The tabs's attributes can be changed with setTabText(), setTabIcon(),-
255 setTabToolTip(), setTabWhatsThis and setTabData(). Each tabs can be-
256 enabled or disabled individually with setTabEnabled().-
257-
258 Each tab can display text in a distinct color. The current text color-
259 for a tab can be found with the tabTextColor() function. Set the text-
260 color for a particular tab with setTabTextColor().-
261-
262 Tabs are added using addTab(), or inserted at particular positions-
263 using insertTab(). The total number of tabs is given by-
264 count(). Tabs can be removed from the tab bar with-
265 removeTab(). Combining removeTab() and insertTab() allows you to-
266 move tabs to different positions.-
267-
268 The \l shape property defines the tabs' appearance. The choice of-
269 shape is a matter of taste, although tab dialogs (for preferences-
270 and similar) invariably use \l RoundedNorth.-
271 Tab controls in windows other than dialogs almost-
272 always use either \l RoundedSouth or \l TriangularSouth. Many-
273 spreadsheets and other tab controls in which all the pages are-
274 essentially similar use \l TriangularSouth, whereas \l-
275 RoundedSouth is used mostly when the pages are different (e.g. a-
276 multi-page tool palette). The default in QTabBar is \l-
277 RoundedNorth.-
278-
279 The most important part of QTabBar's API is the currentChanged()-
280 signal. This is emitted whenever the current tab changes (even at-
281 startup, when the current tab changes from 'none'). There is also-
282 a slot, setCurrentIndex(), which can be used to select a tab-
283 programmatically. The function currentIndex() returns the index of-
284 the current tab, \l count holds the number of tabs.-
285-
286 QTabBar creates automatic mnemonic keys in the manner of QAbstractButton;-
287 e.g. if a tab's label is "\&Graphics", Alt+G becomes a shortcut-
288 key for switching to that tab.-
289-
290 The following virtual functions may need to be reimplemented in-
291 order to tailor the look and feel or store extra data with each-
292 tab:-
293-
294 \list-
295 \li tabSizeHint() calcuates the size of a tab.-
296 \li tabInserted() notifies that a new tab was added.-
297 \li tabRemoved() notifies that a tab was removed.-
298 \li tabLayoutChange() notifies that the tabs have been re-laid out.-
299 \li paintEvent() paints all tabs.-
300 \endlist-
301-
302 For subclasses, you might also need the tabRect() functions which-
303 returns the visual geometry of a single tab.-
