Check a if restoredGeometry fits into availableGeometry This method is used to verify that a widget is restored to a geometry, which fits into the target screen.

Parameters

frameHeight represents the height of the widget's title bar, which is expected to be on its top.

If the size of restoredGeometry exceeds availableGeometry, its height and width will be resized to be two pixels smaller than availableGeometry. An exact match would be full screen.

If at least one edge of restoredGeometry is outside availableGeometry, restoredGeometry will be moved \list

down if its top is off screen
up if its bottom is off screen
right if its left edge is off screen
left if its right edge is off screen \endlist

◆ handleClose()

bool QWidgetPrivate::handleClose ( CloseMode mode )

For windows, this is called from the QWidgetWindow::handleCloseEvent implementation, which QWidget::close indirectly calls by closing the QWindow. mode will be CloseWithEvent if QWidgetWindow::handleCloseEvent is called indirectly by QWindow::close, and CloseWithSpontaneousEvent if the close event originates from the system (i.e. the user clicked the close button in the title bar).

QDialog calls this method directly in its hide() implementation, which might be called from the QDialog::closeEvent override. mode will be set to CloseNoEvent to prevent recursion.

For non-windows, this is called directly by QWidget::close, and mode will be CloseWithEvent.

The function is also called by the QWidget destructor, with mode set to CloseNoEvent.

The graphicsEffect function returns a pointer to the widget's graphics effect.

Since: 4.6

See also: setGraphicsEffect()

The setGraphicsEffect function is for setting the widget's graphics effect.

Sets effect as the widget's effect. If there already is an effect installed on this widget, QWidget will delete the existing effect before installing the new effect.

If effect is the installed effect on a different widget, setGraphicsEffect() will remove the effect from the widget and install it on this widget.

QWidget takes ownership of effect.

Note: This function will apply the effect on itself and all its children.; Graphics effects are not supported for OpenGL-based widgets, such as QGLWidget, QOpenGLWidget and QQuickWidget.
