Dock windows are secondary - windows placed in the \e {dock widget area} around the - \l{QMainWindow::centralWidget()}{central widget} in a - QMainWindow. - - \image mainwindow-docks.png - - Dock windows can be moved inside their current area, moved into - new areas and floated (e.g., undocked) by the end-user. The - QDockWidget API allows the programmer to restrict the dock widgets - ability to move, float and close, as well as the areas in which - they can be placed. - - \section1 Appearance - - A QDockWidget consists of a title bar and the content area. The - title bar displays the dock widgets \link QWidget::windowTitle() - window title\endlink, a \e float button and a \e close button. - Depending on the state of the QDockWidget, the \e float and \e - close buttons may be either disabled or not shown at all. - - The visual appearance of the title bar and buttons is dependent - on the \l{QStyle}{style} in use. - - A QDockWidget acts as a wrapper for its child widget, set with setWidget(). - Custom size hints, minimum and maximum sizes and size policies should be - implemented in the child widget. QDockWidget will respect them, adjusting - its own constraints to include the frame and title. Size constraints - should not be set on the QDockWidget itself, because they change depending - on whether it is docked; a docked QDockWidget has no frame and a smaller title - bar. - - \sa QMainWindow, {Dock Widgets Example} -*/ - -/*! - \enum QDockWidget::DockWidgetFeature - - \value DockWidgetClosable The dock widget can be closed.

In resizeEvent(), the title - bar should check what orientation it should assume: - \snippet doc/src/snippets/code/src_gui_widgets_qdockwidget.cpp 0 - - \o The title bar widget must have a valid QWidget::sizeHint() and - QWidget::minimumSizeHint(). These functions should take into account - the current orientation of the title bar. - - \o It is not possible to remove a title bar from a dock widget. However, - a similar effect can be achieved by setting a default constructed - QWidget as the title bar widget. - \endlist - - Using qobject_cast() as shown above, the title bar widget has full access - to its parent QDockWidget. Hence it can perform such operations as docking - and hiding in response to user actions. - - \sa titleBarWidget() DockWidgetVerticalTitleBar -*/ - -void QDockWidget::setTitleBarWidget(QWidget *widget) -{ - Q_D(QDockWidget); - QDockWidgetLayout *layout - = qobject_cast<QDockWidgetLayout*>(this->layout()); - layout->setWidgetForRole(QDockWidgetLayout::TitleBar, widget); - d->updateButtons(); - if (isWindow()) { - //this ensures the native decoration is drawn - d->setWindowState(true /*floating*/, true /*unplug*/); - } -} - -/*! - \since 4.3 - Returns the custom title bar widget set on the QDockWidget, or 0 if no - custom title bar has been set. - - \sa setTitleBarWidget() -*/ - -QWidget *QDockWidget::titleBarWidget() const -{ - QDockWidgetLayout *layout - = qobject_cast<QDockWidgetLayout*>(this->layout()); - return layout->widgetForRole(QDockWidgetLayout::TitleBar); -} - -QT_END_NAMESPACE - -#include "qdockwidget.moc" -#include "moc_qdockwidget.cpp" - -#endif // QT_NO_DOCKWIDGET |
