Hi!
I am trying to get a semi-transparent (not fully transparent and not fully
white/grey/etc) window background using this as a structure:
# Gtk::Window
-> Gtk::Fixed
-> several buttons
what i am doing atm is setting the app_paintable (
window->set_app_paintable(true); ) flag and drawing to the
window/fixed-layout background before calling present() on it
1. cairo_t *cr = gdk_cairo_create(fix->get_window()->gobj());
2.
3. cairo_set_source_rgba (cr, 1.0, 1.0, 1.0, 0.4); /* transparent */
4. cairo_set_operator (cr, CAIRO_OPERATOR_SOURCE);
5. cairo_paint (cr);
6. cairo_destroy(cr);
this code doesnt give me any visual change (also tried with changed the
layout variable (fix) to the window variable => also doesnt work)
any idea how i can fix that?
gtk version is gtkmm-3.0
