PtInvokeCallbackType()

Invoke a callback list of a specific type

Synopsis:

int PtInvokeCallbackType( PtWidget_t *widget,
                          long type,
                          PtCallbackInfo_t *cbinfo );

Arguments:

widget

The widget pointer to pass to the callbacks as the first argument.

type

The type of callback list to invoke, for example Pt_CB_ARM.

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.

Description:

This function invokes a callback list of type for a widget. It's a convenience function that you can use instead of PtGetCallbackList() and PtInvokeCallbackList().

Returns:

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).
