DESCRIPTION
The QFocusEvent class contains event parameters for widget
focus events.
Focus events are sent to widgets when the keyboard input
focus changes. This happens due to either a mouse action,
the tab key, the window system, a keyboard shortcut or
some other application specific issue. The actual reason
for a specific event is obtained by reason() in the
appropriate event handler.
The event handlers QWidget::focusInEvent() and
QWidget::focusOutEvent() receive focus events.
See also QWidget::setFocus() and
QWidget::setFocusPolicy().
Examples: qmag/qmag.cpp
