Hi,
I checked the documentation but I could not find something appropriate.
I want to display an RGB image with gtk/gdk. Here are some snippets from
the code:
GtkWidget* window;
GtkWidget* drawing_area;
/* create window and drawing area */
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
drawing_area = gtk_drawing_area_new ();
gtk_drawing_area_size (GTK_DRAWING_AREA (drawing_area), 200, 200);
...
GdkVisual* visual = gdk_visual_get_best();
/* create image structure with "best" visual */
image = gdk_image_new(GDK_IMAGE_FASTEST, visual, 200, 200);
gdk_draw_image (window->window,
window->style->fg_gc[GTK_WIDGET_STATE (window)],
image, 0, 0, 0, 0, 200, 200);
Now my problem: gtk_window_new takes the depth of the root window (8 bit
in my case) gdk_visual_get_best returns 24 bit (TrueColor).
How can I create a window widget using the visual returned by
gdk_visual_get_best?
Thanks,
Gerald
