Add several Pt_CB_FILTER entries to a widget
void PtAddFilterCallbacks(
PtWidget_t *widget,
PtRawCallback_t const *callback_defs,
unsigned int num_handlers );
ph
This function adds the number of event handlers specified by num_handlers to the Pt_CB_FILTER callback list that belongs to widget.
| The widget needs to have Pt_GETS_FOCUS set in its Pt_ARG_FLAGS in order to receive key events. |
The callback_defs argument points to an array of PtRawCallback_t, structures. See the Photon Widget Reference.
