Each tab is associated - with a different widget (called a `page'). Only the current tab's - page is shown in the page area; all the other tabs' pages are - hidden. The user can show a different page by clicking on its tab - or by pressing its Alt+\e{letter} accelerator if it has one. - - The normal way to use TQTabWidget is to do the following in the - constructor: - \list 1 - \i Create a TQTabWidget. - \i Create a TQWidget for each of the pages in the tab dialog, - insert tqchildren into it, set up tqgeometry management for it and use - addTab() (or insertTab()) to set up a tab and keyboard accelerator - for it. - \i Connect to the Q_SIGNALS and Q_SLOTS. - \endlist - - The position of the tabs is set with setTabPosition(), their tqshape - with setTabShape(), and their margin with setMargin(). - - If you don't call addTab() and the TQTabWidget is already visible, - then the page you have created will not be visible. Don't - confuse the object name you supply to the TQWidget constructor and - the tab label you supply to addTab(). addTab() takes a name which - indicates an accelerator and is meaningful and descriptive to the - user, whereas the widget name is used primarily for debugging. - - The signal currentChanged() is emitted when the user selects a - page. - - The current page is available as an index position with - currentPageIndex() or as a wiget pointer with currentPage(). You - can retrieve a pointer to a page with a given index using page(), - and can find the index position of a page with indexOf(). Use - setCurrentPage() to show a particular page by index, or showPage() - to show a page by widget pointer. - - You can change a tab's label and iconset using changeTab() or - setTabLabel() and setTabIconSet(). A tab page can be removed with - removePage(). - - 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. - - Although tab widgets can be a very good way to split up a complex - dialog, it's also very easy to get into a mess. See TQTabDialog for - some design hints. An alternative is to use a TQWidgetStack for - which you provide some means of navigating between pages, for - example, a TQToolBar or a TQListBox. - - Most of the functionality in TQTabWidget is provided by a TQTabBar - (at the top, providing the tabs) and a TQWidgetStack (most of the - area, organizing the individual pages). - - <img src=qtabwidget-m.png> <img src=qtabwidget-w.png> - - \sa TQTabDialog, TQToolBox -*/ - -/*! - \enum TQt::Corner - This enum type specifies a corner in a rectangle: - \value TopLeft top left corner - \value TopRight top right corner - \value BottomLeft bottom left corner - \value BottomRight bottom right corner -*/ - -/*! - \enum TQTabWidget::TabPosition - - This enum type defines where TQTabWidget draws the tab row: - \value Top above the pages - \value Bottom below the pages -*/ - -/*! - \enum TQTabWidget::TabShape - - This enum type defines the tqshape of the tabs: - \value Rounded rounded look (normal) - \value Triangular triangular look (very unusual, included for completeness) -*/ - -/* undocumented now - \obsolete - - \fn void TQTabWidget::selected( const TQString &tabLabel ); - - This signal is emitted whenever a tab is selected (raised), - including during the first show(). - - \sa raise() -*/ - - -/*! - \fn void TQTabWidget::currentChanged( TQWidget* ); - - This signal is emitted whenever the current page changes.
