This event handler can be reimplemented to handle state changes.

The state being changed in this event can be retrieved through event event.

Change events include: QEvent::ToolBarChange, QEvent::ActivationChange, QEvent::EnabledChange, QEvent::FontChange, QEvent::StyleChange, QEvent::PaletteChange, QEvent::WindowTitleChange, QEvent::IconTextChange, QEcvent::ModifiedChange, QEvent::MouseTrackingChange, QEvent::ParentChange, QEvent::WindowStateChange, QEvent::LanguageChange, QEvent::LocaleChange, QEvent::LayoutDirectionChange.

[protected, virtual]

This event handler, for event event, can be reimplemented in a subclass to receive widget close events.

Here is the call graph for this function:

void QDesignerFormWindow::resizeEvent

(

QResizeEvent *

rev

)

[protected, virtual]

This event handler can be reimplemented in a subclass to receive widget resize events which are passed in the event parameter. When resizeEvent() is called, the widget already has its new geometry. The old size is accessible through QResizeEvent::oldSize().

The widget will be erased and receive a paint event immediately after processing the resize event. No drawing need be (or should be) done inside this handler.

moveEvent(), event(), resize(), QResizeEvent, paintEvent(), {Scribble Example}
