Nullify the focus of a widget
PtWidget_t *PtContainerNullFocus(
PtWidget_t *widget,
PhEvent_t *event );
This function nullifies the focus of the specified widget's parent. As a result, none of parent's children will have focus.
The event argument contains the event that will be passed to the lost-focus callback of the parent widget and any of its children which were part of the focus chain at the time of this function call.
If event isn't provided, a NULL event will be generated for you.
A pointer to the widget where the focus chain stops. On successful completion, this would be widget's parent.
