DESCRIPTION

26       The QFocusEvent class contains event parameters for widget focus
27       events.
28
29       Focus events are sent to widgets when the keyboard input focus changes.
30       Focus events occur due to mouse actions, keypresses (e.g. Tab or
31       Backtab), the window system, popup menus, keyboard shortcuts or other
32       application specific reasons. The reason for a particular focus event
33       is returned by reason() in the appropriate event handler.
34
35       The event handlers QWidget::focusInEvent() and QWidget::focusOutEvent()
36       receive focus events.
37
38       Use setReason() to set the reason for all focus events, and
39       resetReason() to set the reason for all focus events to the reason in
40       force before the last setReason() call.
41
42       See also QWidget::setFocus(), QWidget::focusPolicy, and Event Classes.

44   Member Type Documentation

QFocusEvent::Reason

46       This enum specifies why the focus changed.
47
48       QFocusEvent::Mouse - because of a mouse action.
49
50       QFocusEvent::Tab - because of a Tab press.
51
52       QFocusEvent::Backtab - because of a Backtab press (possibly including
53       Shift/Control, e.g. Shift+Tab).
54
55       QFocusEvent::ActiveWindow - because the window system made this window
56       (in)active.
57
58       QFocusEvent::Popup - because the application opened/closed a popup that
59       grabbed/released focus.
60
61       QFocusEvent::Shortcut - because of a keyboard shortcut.
62
63       QFocusEvent::Other - any other reason, usually application-specific.
64
65       See the keyboard focus overview for more about focus.
