Re: [GtkGLExt] Fwd: Re: GtkGlExt & GTK3

Because qt developers pay close attention to support opengl than gtk
developers. Qt has been providing support for integration with OpenGL
implementations on all platforms. However if without tdz's hacks for
gtkglext, i do not know when gtk 3 can support opengl.


gtk 3 does support OpenGL. With clutter and cogl you can integrate plain
OpenGL into your application. Maybe it's not as smooth as as Qt's OpenGl
widget, but it is better to use than this abandoned GtkGlExt.

    To bring the list readers up to date, I was helped by Li Yanrui, and
    was able to build GtkGlExt wiith GTK3, with some differences, as
    noted below, from the GTK2 build.  However, I still am unsure
    whether to expect *GtkGlExtMM* to work with GTK3.  Any comments on this?

    With regards to OpenGL working smoothly with GTKExt, I am quite
    satisfied, as both approaches:

    -- gWindow->begin()..... glWikndow->close(), and
    -- glWindow->make_current()

    work well in GTKExt, and, as far as I know, place no restrictions on
    the OpenGL programmer.
    So, I am curious to know in what respects Qt offers a better GTK
    experience for OpenGL programmers, as compared to simply a
    difference in Qt <--> GTK style of programming.

    Thank you for the responses.

    Sorry, i do not know the things of gtkglextmm. If i want to use c++,
    i will think qt + opengl. In fact i am hard to bear gtk+ with opengl :)

        Thanks, my mistake.  I used the wrong git repository.

        One difference from the official install, is that you must do
        the configure in the gtkglext folder.  it does not work to
        create, and work in, a separate "build" folder.  Two mistakes
        occur if you try:
        -- gdk/Makefile.in does not get created
        -- the GOBJECT_INTROSPECTION_CHECK fails.

        The build worked!

        Do you know if *GtkGlExtMM* works with this version 3?

            Thanks for the pointer.  Compile error as shown, below. 
            Currently, I am successfully working with GtkGlExtMM and
            GTK2, so if GTK3 support is still "in the works", maybe it
            is not worth spending time on my GTK3 problem -- unless I
            am able to help to expedite getting GTKGlExtMM working
            with GTK3.   What do you think?

            So, the above being said, here is what I have done:
            (I am on fedora19, 32 bit, x86)

            git clone git://git.gnome.org/gtkglext
            <http://git.gnome.org/gtkglext>

            cd gtkglext
            ./bootstrap

            mkdir build
            cd build
            ../configure  CPPFLAGS=-I/usr/include/nvidia
            make

            Here is the first error:

                The net has conflicting information on the status of
                using GtkGlkExt with GTK3.
                What is the latest scoop, please?
