Detailed 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
