Nullify the focus of a widget
PtWidget_t *PtContainerNullFocus(
PtWidget_t *widget,
PhEvent_t *event );
ph
This function nullifies the focus of the specified widget's
parent. As a result, none of parent's children has
focus.
The event argument is a pointer to a
PhEvent_t,
structure that describes the event to be passed
to the lost-focus callback of the parent widget and any of its
children that were part of the focus chain at the time of this
function call.
If event is NULL, this function generates a
PhEvent_t structure filled with zeros for you.
A pointer to the widget where the focus chain stops. On successful
completion, this is widget's parent.
See PtContainerGiveFocus().
