I tried now the following, but it still doesn't work:
int main(int argc, char *argv[])
{
auto app = Gtk::Application::create(argc, argv, "org.gtkmm.example");
Gtk::Window window;
Gtk::Button button("Some text");
window.add(button);
Gdk::RGBA color;
color.set_rgba(0xff,0x00,0x00,1.0);
Glib::RefPtr<Gtk::CssProvider> css_provider =
Gtk::CssProvider::create();
css_provider->load_from_data("button {background-color: #ff0000;}");
button.get_style_context()->add_provider( css_provider,
GTK_STYLE_PROVIDER_PRIORITY_USER);
window.show_all_children();
return app->run(window);
}
Any ideas?
Where can I find the reference which styles from the style sheet each of
the widgets uses? Is there something like a tag/value reference??
I still only want to set the background color of a single button :-)
