Constructor & Destructor Documentation

◆ QMainWindowLayoutState()

QMainWindowLayoutState::QMainWindowLayoutState ( QMainWindow * win )

QDockWidgetGroupWindow is a floating window, containing several QDockWidgets floating together. This requires QMainWindow::GroupedDragging to be enabled. QDockWidgets floating jointly in a QDockWidgetGroupWindow are considered to be docked. Their isFloating property is false. QDockWidget children of a QDockWidgetGroupWindow are either: \list

tabbed (as long as Qt is compiled with the tabbar feature), or
arranged next to each other, equivalent to the default on a main window dock. \endlist

QDockWidgetGroupWindow uses QDockWidgetGroupLayout to lay out its QDockWidget children. It stores layout information in a QDockAreaLayoutInfo, including temporary spacer items and rubber bands.

If its QDockWidget children are tabbed, the QDockWidgetGroupWindow shows the active QDockWidget's title as its own window title.

QDockWidgetGroupWindow is designed to hold more than one QDockWidget. A QDockWidgetGroupWindow with only one QDockWidget child may occur only temporarily \list

in its construction phase, or
during a hover: While QDockWidget A is hovered over B, B is converted into a QDockWidgetGroupWindow. \endlist

A QDockWidgetGroupWindow with only one QDockWidget child must never get focus, be dragged or dropped. To enforce this restriction, QDockWidgetGrouWindow will remove itself after its second QDockWidget child has been removed. It will make its last QDockWidget child a single, floating QDockWidget. Eventually, the empty QDockWidgetGroupWindow will call deleteLater() on itself.
