[maemo-developers] Qt with OpenGL ES 1.1 on Maemo / N900

[From: Thomas Perl]

Hello!

According to the OpenGL ES Wiki page[1], Qt on Maemo only supports
OpenGL ES 2.x. Is this really true? I've added the following two lines
to my .pro file, and my application compiles, links and runs happily.
However, the window (a QGLWidget) will stay black - nothing is drawn
on the screen.

DEFINES += QT_NO_OPENGL_ES_2 QT_OPENGL_ES_1
LIBS += -lGLES_CM

Now my questions:

1.) Is it possible to use QGLWidget with OpenGL ES 1.1 on the N900?
2.) Is there a minimal example using QGLWidget + OpenGL ES 1.1?

The same code works fine when compiled with Qt under Ubuntu on a
laptop, so the code works and does draw something ;) I'm using the
experimental Qt 4.7.x packages from Extras-Devel in Scratchbox and on
the device.

Any help appreciated :)

Thanks!
Thomas
