By default, the - tab bar is shown above the page area, but different configurations - are available (see \l{TabPosition}). Each tab is associated with a - different widget (called a page). Only the current page is shown in - the page area; all the other pages are hidden. The user can show a - different page by clicking on its tab or by pressing its - Alt+\e{letter} shortcut if it has one. - - The normal way to use QTabWidget is to do the following: - \list 1 - \i Create a QTabWidget. - \i Create a QWidget for each of the pages in the tab dialog, but - do not specify parent widgets for them. - \i Insert child widgets into the page widget, using layouts to - position them as normal. - \i Call addTab() or insertTab() to put the page widgets into the - tab widget, giving each tab a suitable label with an optional - keyboard shortcut. - \endlist - - The position of the tabs is defined by \l tabPosition, their shape - by \l tabShape. - - The signal currentChanged() is emitted when the user selects a - page. - - The current page index is available as currentIndex(), the current - page widget with currentWidget(). You can retrieve a pointer to a - page widget with a given index using widget(), and can find the - index position of a widget with indexOf(). Use setCurrentWidget() - or setCurrentIndex() to show a particular page. - - You can change a tab's text and icon using setTabText() or - setTabIcon(). A tab and its associated page can be removed with - removeTab(). - - Each tab is either enabled or disabled at any given time (see - setTabEnabled()). If a tab is enabled, the tab text is drawn - normally and the user can select that tab. If it is disabled, the - tab is drawn in a different way and the user cannot select that - tab. Note that even if a tab is disabled, the page can still be - visible, for example if all of the tabs happen to be disabled. - - Tab widgets can be a very good way to split up a complex dialog. - An alternative is to use a QStackedWidget for which you provide some - means of navigating between pages, for example, a QToolBar or a - QListWidget. - - Most of the functionality in QTabWidget is provided by a QTabBar - (at the top, providing the tabs) and a QStackedWidget (most of the - area, organizing the individual pages). - - \table 100% - \row \o \inlineimage windowsxp-tabwidget.png Screenshot of a Windows XP style tab widget - \o \inlineimage macintosh-tabwidget.png Screenshot of a Macintosh style tab widget - \o \inlineimage plastique-tabwidget.png Screenshot of a Plastique style tab widget - \row \o A Windows XP style tab widget. - \o A Macintosh style tab widget. - \o A Plastique style tab widget. - \endtable - - \sa QTabBar, QStackedWidget, QToolBox, {Tab Dialog Example} -*/ - -/*! - \enum QTabWidget::TabPosition - - This enum type defines where QTabWidget draws the tab row: - - \value North The tabs are drawn above the pages. - \value South The tabs are drawn below the pages. - \value West The tabs are drawn to the left of the pages. - \value East The tabs are drawn to the right of the pages. - \omitvalue Bottom - \omitvalue Top -*/ - -/*! - \enum QTabWidget::TabShape - - This enum type defines the shape of the tabs: - \value Rounded The tabs are drawn with a rounded look.
