I already use FrmDoDialog to show a lot of forms in my programs, I wrote the
next 3 functions to popup forms.
FormPtr
InitDialog(UInt16 rscID, FormEventHandlerType *handler)
{
FormPtr frmP;
frmP = FrmInitForm(rscID);
FrmSetActiveForm(frmP);
FrmSetEventHandler(frmP, handler);
FrmDrawForm(frmP);
return frmP;
}
UInt32
EndDialog(FormPtr frmP, FormPtr frm2P)
{
UInt32 rscID;
// ErrDisplay("Terminar Dialog");
rscID = FrmDoDialog(frmP);
FrmDeleteForm(frmP);
FrmSetActiveForm(frm2P);
return rscID;
}
void
DeleteDialog(FormPtr frmP, FormPtr frm2P)
{
FrmEraseForm(frmP);
FrmDeleteForm(frmP);
FrmSetActiveForm(frm2P);
}
I always use InitDialog(), but when I had a button to be pressed I use
EndDialog(), and where there is no button to press I use DeleteDialog(). I
also nest this functions to show other popup forms when certain field or
button is pressed on the first popup, and then I need to popup another form
to show/adquire data. I always used the first popup form having an OK
button, and I simply use CtlHitControl ((ControlPtr)FrmGetObjectPtr (frmP,
FrmGetObjectIndex(frmP, ObjectID))); after the second popup form is closed
either by EndDialog() or DeleteDialog(), to get the first popup form to get
closed.
Hope this can help you out to solve your issue.
