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 |
