Random, somewhat old to-do list:
(See Issue Tracker on http://jogl.dev.java.net/ for current high-priority issues)
- Non-const array types must be properly released with JNI_COMMIT in
order to see side effects if the array was copied.
- Figure out how to implement GLEventListener.displayChanged(bool,bool).
I believe we need additional support in J2SE before this will be possible
to detect and implement. The basic problem is that we need to find a way
to determine when a GLCanvas has moved to a different
display device, so we can re-load the GL function addresses using
wgl/glXGetProcAddress. See comments at top of GLCanvas.java. Also need a
way to determine with the display mode (e.g., bit depth) of the GLDrawable
has changed. Once both of these problems are solved, we'll need to hook it
into GLEventListener.displayChanged() and also be sure to reset the
GLDrawable's glProcAddress table as appropriate.
- Think about e.g. protected access for Impl classes
- Fix glProgramStringARB and glGetProgramString{NV,ARB} so that they
use Strings and/or StringBuffers insteead of GLUbyte* and void*
- figure out how to deal with WGL entry points:
WINGDIAPI HGLRC WINAPI wglCreateLayerContext(HDC, int);
WINGDIAPI BOOL WINAPI wglUseFontBitmapsA(HDC, DWORD, DWORD, DWORD);
WINGDIAPI BOOL WINAPI wglUseFontBitmapsW(HDC, DWORD, DWORD, DWORD);
see commented-out section in make/stub_includes/win32/wingdi.h
- Need a disciplined mechanism for converting char* argument types. For
example, many C functions accept a "char*" argument with the semantic that
output data will be written into the buffer pointed to by the
argument. The type "const char*" is used when the argument's data will be
unchanged. Our system needs a new directive, such as
"ArgumentIsStringBuffer" to be used for type conversion in those cases
where the native code needs to write output into the "char*" argument. Not
sure how to handle this on the native side -- it may require hints to the
native code generator as to how large the StringBuffer's backing buffer
needs to be, so we can assert this condition before passing the backing
buffer to the C function we are wrapping.
- Throw an exception if native calls to GetPrimitiveArrayCritical
return null.
- Before emitting functions and constants, sort them first by
extension suffix (i.e., ARB, ATI, NV, etc) and then by name. This
will organize them in the file more logically. When writing the
code, the sort function can check the last substring that's all caps,
and treat this as the extension owner. Be careful though, some end
in "3D" and that's not an extension.
