GrfSetState() should work; try w/o the GrfInitState(). Here's what I
use; it works for me for OS 1.0 through 3.5:
#include <Graffiti.h>
...
FooFormHandleEvent(EventPtr event)
{
static Word tempState ;
static Boolean capsState, ignore ;
...
case frmOpenEvent:
/* save current Graffiti shift state */
GrfGetState(&capsState,&ignore,&tempState,&ignore) ;
...
FrmDrawForm(form) ;
GrfSetState(true,false,false) ; /* set caps lock */
handled = true ;
break ;
...
case ctlSelectEvent:
...
case FooOkayButton:
...
/* restore Graffiti state and return to main (previous) form */
GrfSetState(capsState,false,false) ;
FrmReturnToForm(0) ;
...
...
}
The call to GrfGetState() on frmOpenEvent is so that you can restore
Graffiti to its previous state when you leave the form (if you're
doing this in your main form, then you don't need to worry about
saving and restoring the Graffiti state); this isn't necessary for
setting the shift state though (and doesn't always seem to work
reliably across all OS versions).
Hope this helps,
John
