PtRemoveCallbacks()

Remove several callback entries from a callback list

Synopsis:

void PtRemoveCallbacks( 
        PtWidget_t *widget,
        unsigned long callback_type,
        PtCallback_t const *callback_defs,
        unsigned int num_callbacks );

Description:

This function removes the first callback entries that exactly match an entry in the callback_defs array. It removes these entries from the callback_type callback list that belongs to widget. The num_callbacks argument specifies the length of the array.

Note:

Some types of callback resources have special routines that you should use instead of this one:

Pt_CB_HOTKEY: PtRemoveHotkeyHandler()
Pt_CB_RAW: PtRemoveEventHandler() or PtRemoveEventHandlers()

Examples:

See PtAddCallback().
