Using GnoclOption functions to Return Values for Customised Widget Options.

What to do...

Make changes to the widgetFunc function to enable the GnoclOption function for that option to return a value by setting the ret to point ot a TclObj.

/* this is a gnocl option handler ?? */

case GNOCL_CGET_NOTHANDLED: {

/* cget for gnocl options handled in option function
* the caveat here is that different widgets with the same option name may act differently,
* if this is the case, then would it be more practical to create specific option functions?
* (08/09/25)
*/

Tcl_Obj *ret = NULL;

options[idx2].func ( interp, &options[idx2], G_OBJECT ( area ), &ret );

Tcl_SetObjResult (interp, ret);

}
