At this moment I have experience with ARM Tegra 2 with X11
My application use GTK+ for user interface (widows, buttons ,menu etc..)
Some parts of UI use OpenGL ES over EGL
Sample code: http://bobthegnome.blogspot.com/2014/09/using-egl-with-gtk.html
static void realize_cb (GtkWidget *widget) { EGLConfig egl_config; EGLint n_config; EGLint attributes[] = { EGL_RENDERABLE_TYPE, EGL_OPENGL_BIT, EGL_NONE }; egl_display = eglGetDisplay ((EGLNativeDisplayType) gdk_x11_display_get_xdisplay (gtk_widget_get_display (widget))); eglInitialize (egl_display, NULL, NULL); eglChooseConfig (egl_display, attributes, &egl_config, 1, &n_config); eglBindAPI (EGL_OPENGL_API); // or EGL_OPENGL_ES_API !!!! egl_surface = eglCreateWindowSurface (egl_display, egl_config, gdk_x11_window_get_xid (gtk_widget_get_window (widget)), NULL); egl_context = eglCreateContext (egl_display, egl_config, EGL_NO_CONTEXT, NULL); }
This function create egl_display, egl_surface, egl_context From GtkWidget
At this moment i try migrate applcation to "imx8 mini"
Where is the problem: wayland don't have functions gdk_x11_.... it is wayland, OK
But how to fix it ? How to create egl context in GTK+ ? Is it possible ?
Hello MariusMaximus,
No, You need to check the file to disable-x11-backend none of i.MX8 have an X11 backend, and gtk+ is X11 specific.
Regards
>> gtk+ is X11 specific.
In my opinion , I don't think you're right . I have build "DISTRO=fsl-imx-wayland " for my imx8 , GTK+ application works OK. I don't have any X11 lib in my image.
Please look at this video https://www.youtube.com/watch?v=fr8eo4RlPw4
web browser as backend for gtk+application , I just found it
In my Old application on X11 I have 2 windows.Window [2] has parent set to Window [1]
I'd like to do the same on wayland
I can create EGL context in window created by "wl_egl_window_create"
And I have for moment
But widows are independend , after focus window [1] I see
