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.

◆ applyRestoredState()

void QMainWindowLayout::applyRestoredState ( )

restoredState stores what we earlier read from storage, but it couldn't be applied as the mainwindow wasn't large enough (yet) to fit the state. Usually, the restored state would be applied lazily in setGeometry below. However, if the mainwindow's layout is modified (e.g. by a call to tabify or splitDockWidgets), then we have to forget the restored state as it might contain dangling pointers (QDockWidgetLayoutItem has a copy constructor that copies the layout item pointer, and splitting or tabify might have to delete some of those layout structures).

Functions that might result in the QMainWindowLayoutState storing dangling pointers have to call this function first, so that the restoredState becomes the actual state first, and is forgotten afterwards.

This function can be used to iterate over a layout. The following code will draw a rectangle for each layout item in the layout structure of the widget.

{
QLayout *layout = item->layout();
if (layout) {
for (int i = 0; i < layout->count(); ++i)

◆ minimumSize()

Returns the minimum size of this layout.

This is the smallest size that the layout can have while still respecting the specifications.

The returned value doesn't include the space required by QWidget::setContentsMargins() or menuBar().

The default implementation allows unlimited resizing.
