A child focus event is sent to a (parent-)window when one of its child windows gains focus, so that the window could restore the focus back to its corresponding child if it loses it now and regains later.
Notice that child window is the direct child of the window receiving event. Use find_focus to retreive the window which is actually getting focus.
To process a child focus event, use this event handler macro to direct input to a member function that takes a ChildFocusEvent argument.
| evt_child_focus() { | event | ... } | Process a EVT_CHILD_FOCUS event. |
ChildFocusEvent.new(Window win = nil)Constructor.
Returns the direct child which receives the focus, or a (grand-)parent of the control receiving the focus.
To get the actually focused control use Window#find_focus.
