234 \class QTabBar-
235 \brief The QTabBar class provides a tab bar, e.g. for use in tabbed dialogs.-
236-
237 \ingroup basicwidgets-
238 \inmodule QtWidgets-
239-
240 QTabBar is straightforward to use; it draws the tabs using one of-
241 the predefined \l{QTabBar::Shape}{shapes}, and emits a-
242 signal when a tab is selected. It can be subclassed to tailor the-
243 look and feel. Qt also provides a ready-made \l{QTabWidget}.-
244-
245 Each tab has a tabText(), an optional tabIcon(), an optional-
246 tabToolTip(), optional tabWhatsThis() and optional tabData().-
247 The tabs's attributes can be changed with setTabText(), setTabIcon(),-
248 setTabToolTip(), setTabWhatsThis and setTabData(). Each tabs can be-
249 enabled or disabled individually with setTabEnabled().-
250-
251 Each tab can display text in a distinct color. The current text color-
252 for a tab can be found with the tabTextColor() function. Set the text-
253 color for a particular tab with setTabTextColor().-
254-
255 Tabs are added using addTab(), or inserted at particular positions-
256 using insertTab(). The total number of tabs is given by-
257 count(). Tabs can be removed from the tab bar with-
258 removeTab(). Combining removeTab() and insertTab() allows you to-
259 move tabs to different positions.-
260-
261 The \l shape property defines the tabs' appearance. The choice of-
262 shape is a matter of taste, although tab dialogs (for preferences-
263 and similar) invariably use \l RoundedNorth.-
264 Tab controls in windows other than dialogs almost-
265 always use either \l RoundedSouth or \l TriangularSouth. Many-
266 spreadsheets and other tab controls in which all the pages are-
267 essentially similar use \l TriangularSouth, whereas \l-
268 RoundedSouth is used mostly when the pages are different (e.g. a-
269 multi-page tool palette). The default in QTabBar is \l-
270 RoundedNorth.-
271-
272 The most important part of QTabBar's API is the currentChanged()-
273 signal. This is emitted whenever the current tab changes (even at-
274 startup, when the current tab changes from 'none'). There is also-
275 a slot, setCurrentIndex(), which can be used to select a tab-
276 programmatically. The function currentIndex() returns the index of-
277 the current tab, \l count holds the number of tabs.-
278-
279 QTabBar creates automatic mnemonic keys in the manner of QAbstractButton;-
280 e.g. if a tab's label is "\&Graphics", Alt+G becomes a shortcut-
281 key for switching to that tab.-
282-
283 The following virtual functions may need to be reimplemented in-
284 order to tailor the look and feel or store extra data with each-
285 tab:-
286-
287 \list-
288 \li tabSizeHint() calcuates the size of a tab.-
289 \li tabInserted() notifies that a new tab was added.-
290 \li tabRemoved() notifies that a tab was removed.-
291 \li tabLayoutChange() notifies that the tabs have been re-laid out.-
292 \li paintEvent() paints all tabs.-
293 \endlist-
294-
295 For subclasses, you might also need the tabRect() functions which-
296 returns the visual geometry of a single tab.-
