GtkGLArea with GtkOffscreenWindow




Hello,

   Consider the following program:


int main()
{
gtk_init(nullptr,nullptr);

auto window = gtk_offscreen_window_new();
auto gl_area = gtk_gl_area_new();

gtk_container_add(GTK_CONTAINER(window),gl_area);

gtk_widget_realize(gl_area);

gtk_widget_show_all(window);

auto glContext = gtk_gl_area_get_context(GTK_GL_AREA(gl_area));

std::cout << "Context is " << glContext << std::endl;

gtk_main();
}
  

The glContext is null. Can GtkGLArea work with GtkOffscreenWindow?


Thanks,

Rob Conde
