62 \class QTabWidget -
63 \brief The QTabWidget class provides a stack of tabbed widgets. -
64 -
65 \ingroup organizers -
66 \ingroup basicwidgets -
67 \inmodule QtWidgets -
68 -
69 A tab widget provides a tab bar (see QTabBar) and a "page area" -
70 that is used to display pages related to each tab. By default, the -
71 tab bar is shown above the page area, but different configurations -
72 are available (see \l{TabPosition}). Each tab is associated with a -
73 different widget (called a page). Only the current page is shown in -
74 the page area; all the other pages are hidden. The user can show a -
75 different page by clicking on its tab or by pressing its -
76 Alt+\e{letter} shortcut if it has one. -
77 -
78 The normal way to use QTabWidget is to do the following: -
79 \list 1 -
80 \li Create a QTabWidget. -
81 \li Create a QWidget for each of the pages in the tab dialog, but -
82 do not specify parent widgets for them. -
83 \li Insert child widgets into the page widget, using layouts to -
84 position them as normal. -
85 \li Call addTab() or insertTab() to put the page widgets into the -
86 tab widget, giving each tab a suitable label with an optional -
87 keyboard shortcut. -
88 \endlist -
89 -
90 The position of the tabs is defined by \l tabPosition, their shape -
91 by \l tabShape. -
92 -
93 The signal currentChanged() is emitted when the user selects a -
94 page. -
95 -
96 The current page index is available as currentIndex(), the current -
97 page widget with currentWidget(). You can retrieve a pointer to a -
98 page widget with a given index using widget(), and can find the -
99 index position of a widget with indexOf(). Use setCurrentWidget() -
100 or setCurrentIndex() to show a particular page. -
101 -
102 You can change a tab's text and icon using setTabText() or -
103 setTabIcon(). A tab and its associated page can be removed with -
104 removeTab(). -
105 -
106 Each tab is either enabled or disabled at any given time (see -
107 setTabEnabled()). If a tab is enabled, the tab text is drawn -
108 normally and the user can select that tab. If it is disabled, the -
109 tab is drawn in a different way and the user cannot select that -
110 tab. Note that even if a tab is disabled, the page can still be -
111 visible, for example if all of the tabs happen to be disabled. -
112 -
113 Tab widgets can be a very good way to split up a complex dialog. -
114 An alternative is to use a QStackedWidget for which you provide some -
115 means of navigating between pages, for example, a QToolBar or a -
116 QListWidget. -
117 -
118 Most of the functionality in QTabWidget is provided by a QTabBar -
119 (at the top, providing the tabs) and a QStackedWidget (most of the -
120 area, organizing the individual pages). -

401 If the tab's \a label contains an ampersand, the letter following -
402 the ampersand is used as a shortcut for the tab, e.g. if the -
403 label is "Bro\&wse" then Alt+W becomes a shortcut which will -
404 move the focus to this tab. -
405 -
406 If \a index is out of range, the tab is simply appended. -
407 Otherwise it is inserted at the specified position. -

411 less than or equal to the current index will increment the current -
412 index, but keep the current page. -
413 -
414 \note If you call insertTab() after show(), the layout system will try -
415 to adjust to the changes in its widgets hierarchy and may cause -
416 flicker. To prevent this, you can set the QWidget::updatesEnabled -
417 property to false prior to changes; remember to set the property -
418 to true when the changes are done, making the widget receive paint -
419 events again. -
