Well, AFAIK there are usually two approaches to this:
a. a "smart" form that handles most the progress stuff
b. a "dumb" form that just updates a meter when told
One easy way is to open the form and roll your own event
loop from there.
This assumes that the progress form is smart and allocates
time handling to the function that needs a progress meter. The
other approach would be to allocate time to detect events in
the progress form.
Hope this helps,
Daniel.
For example... (smart progress form)
curForm = FrmGetActiveForm();
frm = FrmInitForm(MyProgressFormID);
FrmSetActiveForm(frm);
FrmDrawForm(frm);
while (!done) {
EvtGetEvent(&event, evtWaitForever);
handled = FrmHandleEvent(frm, &event);
if (SysHandleEvent(&event))
continue;
if (event.eType == ctlSelectEvent) {
switch (event.data.ctlSelect.controlID) {
case MyCancelButtonID:
done = true;
break;
}
else if (event.eType == appStopEvent) {
EvtAddEventToQueue(&event);
break;
}
}
FrmEraseForm(frm);
FrmDeleteForm(frm);
if (curForm)
FrmSetActiveForm(curForm);
