[gl4java-usergroup] Re: Mac OS X Issue

[Alban Cousini <aco...@wa...>]

Hi Mark,

I am facing the same issue while porting OpenMind on MacOSX. On my machine,
I get this error only in fullscreen mode. Since no sample provided with the
MacOSX release of gl4java uses fullscreen mode, I beleive the compatibility
for fullscreen mode has not been implemented, but we should ask Gerard
Ziemsky what he knows about this issue. Running your program in a regular
window should work fine.

Another issue I have been facing was an "invalid drawable" error. It occurs
when you try to create a GLAnimCanvas inside a Jframe. There is an
incompatibility. Thus if you want to use swing, create a regular awt Frame,
and add your GLAnimCanvas to it. You can always add swing UI components to
this frame, but the Window component must not be a Jframe.

I'd be interested to know if you found a workaround for this error as I am
myself interested into MacOSX.

Gerard Ziemsky told me he was no longer expecting to support the MacOSX por=
t
of gl4java because the implementation has become too complicate. Apparently=
,
the Java 1.4.1 implementation has been done by someaone named Dmitry
Markman.=20
Sven Gothel has been giving very few signs of life lately and is answering
less and less my emails since a few monthes. I'm getting pretty worried
about the future of gl4java in general and it's MacOSX implementation in
particular. I hope the API is not going to die slowly... If someone has som=
e
more optimistic news, I'd be interested to ear these.
