Invoke the List Key method in a superclass
int PtSuperClassGenListKey(
PtWidgetClassRef_t *cref,
PtWidget_t *wgt,
PhEvent_t *ev,
PhKeyEvent_t *kev,
PtGenListItem_t *newcur,
unsigned newpos );
- cref
- The superclass whose method you want to call.
- wgt
- A pointer to the widget for which to call the superclass's method.
- ev
- A pointer to a
PhEvent_t
structure (see the Photon Library Reference) that defines the
event.
- kev
- A pointer to a
PhKeyEvent_t
structure (see the Photon Library Reference) that defines the
event data.
The function can modify this structure.
- newcur
- A pointer to a
PtGenListItem_t
structure (see the Photon Widget Reference) for the new
current item (if the event is processed normally).
- newpos
- The index of that item (the first item on the list has an index of 1).
This function can be used to invoke the List Key method of the
class defined by cref.
A nonzero value if the key event was consumed, 0 otherwise.
