I'm attempting to follow the instructions in Apple's Carbon ****ting Guide,
to ****t an OS9 PowerPlant app to OSX (using PP 2.2.2). I'm at the first
stage, where you try to carbonize the code, while linking to your normal
libraries, plus CarbonAccessors.o.
I have #defined:
#define ACCESSOR_CALLS_ARE_FUNCTIONS 1
#define OPAQUE_TOOLBOX_STRUCTS 1
....and I have fixed all the errors related to the opaque structures etc,
and
am able to link and run.
However, I'm having a problem where, in PowerPlant's
LWindow::Update****t(),
the updateRgn for every single window in the application is empty when
Update****t() is called, and so it exits and nothing is drawn in any of the
windows.
It calls ::GetWindowRegion(mMacWindowP, kWindowUpdateRgn, updateRgn).
Universal Headers states that this function is supposed to be available in
CarbonAccessors.o. But it always is returning an empty region.
If I comment out the test for ::EmptyRgn(updateRgn), then the rest of the
code in LWindow::Update****t() is performed, and they all draw as per
normal.
Obviously, this isn't the fix I need. ;-)
Anybody hear of this problem before? I've been trying to track what might
be
causing this, and I don't have a clue yet.
Thanks,
