Give focus to the previous widget
PtWidget_t *PtGlobalFocusPrev( PtWidget_t *widget, PhEvent_t *event );
This function finds the currently focused widget in the same disjoint widget (window, region, menu) as widget and moves the focus to the previous focusable widget.
The widget that's given focus receives event as the reason. If event is NULL, this function generates a PhEvent_t structure filled with zeros for you.
The widget that was given focus, or NULL if no focusable widgets are found.
