I see in the mailing list that gtkmm4 is coming... :-)
Will goocanvasmm-2 also work with upcoming gtkmm4? Maybe is there a new
release like goocanvasmm-3? Can anyone test if it still compiles within
gtkmm4.

gotchas will probably be found by checking what the default theme does.
that'll be gtk/themes/Adwaita/_common.scss in the Git repository.
you can either work with/over those, or if you really wanted just write
your own theme... or unset props for entire widgets before theming them.

Thank you very much!
I now have an entry point!
I now found the background, background-color and background-image

see C GTK docs for CSS node/class info. i can't recall whether gtkmm's
doc conversion preserves that section.
Can you point me to the docs? I searched a lot but did not find it.

that is another typical 'gotcha'. you need to unset the background-image,
or just set the shorthand background property instead of
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;
Thanks!
Is there any example available to set the background color of a button

Gtk::Window window;
Gtk::Button button("Some text");
window.add(button);
