Hi everybody,
I am learning to use PRC to Overlay tool in Palm. I have a form with 3 objects. I want
to make an overlay PRC with just 2 objects. I get stuck because I don't know how to do
this:
1. If I call FrmGetFormPtr() in AppStart(), it return 0. If I call FrmGetFormPtr() or
FrmGetActiveForm() in frmOpenEvent, it works fine. Why ?
2. If I'd like to find whether an object is existing in a form or not, can I do it or
not? which API can I use?
3. I have a gadget in my form, I do some custom draw (WinDrawLine(), etc.) in the
gadget. When I set gadget unusable (uncheck the usable box), it still draws. Why?
How do I check the value of usable of that gadget?
How do I set the value of usable of that gadget?
Can anybody tell me how to do 1. 2. 3. or how to make an overlay PRC with 2 objects.
Is there any more documents about PRC to Overlay other than 7 pages OVERLAY TOOL from
Palm site?
Thank you for reading and helping me.
tnn
