Is there a platform independant way of obtaining a Window and

no. evas_gl replaces egl. it's done this way because there are so
many other things you want to use the widget infrastructure for like
indicator, kbd handling (eg sizing content to move out of the way of
the kbd) etc. and if you use evas_gl you can merge both ui, widgets
gl api.
you simply need to change the egl parts (it's actually less work
using elm_glview than using egl - by far) and ensure your rendering
all happens in the render callback.
Carsten,
Sounds good for creating a new application.
I was investigating the work required to port an existing application.
I noticed the EGL and GLES libraries exist on the tizen platform
emulator.
yes - but you can't use them if you ever want to ship/distribute your
app. platform components only as they can change to move display
systems.
I was thinking of writing a wrapper library, that implements GLES2.0
around evas_gl. A Tizen application has it's own lib directory, if
I install the wrapper library into this directory, will it be
resolved instead of the system GLES libraries?
i ... don't know actually. i do know that evas_gl and egl are not an
exact 1:1 match and there are other things like NO swapbuffers so you
structure code differently.
you are best off restructuring the egl code and isolating it in a
porting layer etc.
Thanks,
Peter.
Thank you Carsten,
Ignoring the display layer for a moment, the underlying system is Linux,
I was going to bundle an Embedded JVM with the application (written in
Java) using JOGL - Java Open GL bindings.
Java has JNI which allows it to call C libraries and be invoked by C code.
It would be nice if Tizen supported Java as well, don't know if there
are any plans in future to do so?
Regards,
Peter.
