Member Function Documentation

◆ addItem()

void QMainWindowLayout::addItem ( QLayoutItem * item )

overridevirtual

Implemented in subclasses to add an item.

How it is added is specific to each subclass.

This function is not usually called in application code. To add a widget to a layout, use the addWidget() function; to add a child layout, use the addLayout() function provided by the relevant QLayout subclass.

{Note:} The ownership of item is transferred to the layout, and it's the layout's responsibility to delete it.

This event handler can be reimplemented in a subclass to receive timer events for the object.

QTimer provides a higher-level interface to the timer functionality, and also more general information about timers. The timer event is passed in the event parameter.

See also: startTimer(), killTimer(), event()

Reimplemented from QObject.

Here is the call graph for this function:

◆ unplug()

QLayoutItem * QMainWindowLayout::unplug	(	QWidget *	widget,
		bool	group = `false`
	)

Unplug widget (QDockWidget or QToolBar) from it's parent container.

If group is true we might actually unplug the group of tabs this widget is part if QMainWindow::GroupedDragging is set. When group is false, the widget itself is always unplugged alone

Returns the QLayoutItem of the dragged element. The layout item is kept in the layout but set as a gap item.
