Invoke a callback list
int PtInvokeCallbackList( PtCallbackList_t *cb_list,
PtWidget_t *widget,
PtCallbackInfo_t *cbinfo );
- cb_list
- The list of callbacks to invoke.
- widget
- The widget pointer to pass to the callbacks as the first argument.
- cbinfo
- A pointer to a
PtCallbackInfo_t
structure (see the Photon Widget Reference) that's
passed to each callback in the list as the third argument.
This function invokes the provided callback list cb_list.
The cb_data member of each item in the callback list is passed as
the second argument to the associated callback.
A return status
from the callback list:
- Pt_CONTINUE
- Pt_HALT
- Pt_END
If the returned status is Pt_END, have your function
consume the event (i.e. return Pt_END).
