The QFocusEvent class contains event parameters for widget focus events. More...
List of all member functions.
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().
Mouse- the focus change happened because of a mouse action
Tab- the focus change happened because of a Tab press (possibly including shift/control)
ActiveWindow- the window system made this window (in)active
Popup- the application opened/closed a popup that grabbed/released focus
Shortcut- the focus change happened because of a keyboard shortcut
Other- any other reason, usually application-specific
