I'm playing around with gadgets and I have a question about the data that
can be stored with them.
Lets say I want to associate an integer with a gadget and I do something
like the following:
VoidHand vh;
FormPtr frm = FrmGetActiveForm();
vh = MemHandleNew (sizeof(UInt16));
if (vh)
{
* (UInt16 *) MemHandleLock (vh) = 1;
MemHandleUnlock (vh);
FrmSetGadgetData (frm, FrmGetObjectIndex (frm, MyGadgetID), vh);
}
What happens to the old data that was associated with the gadget (assuming I
had called the above at least once before)?
And... (somewhat of a C related question I think), if I have a second gadget
named MyGadgetID2, is it legal to follow the above code with this:
FrmSetGadgetData (frm, FrmGetObjectIndex (frm, MyGadgetID2), vh);
