I know you can remove a button's relief with

button.set_relief(Gtk::RELIEF_NONE);   // gtkmm

Or 

gtk_button_set_relief(button, GTK_RELIEF_NONE);   // gtk

But there's no corresponding method for a combobox.

What's the easiest way to accomplish this?

  • You can do this by adding a [GtkCssProvider](https://developer.gnome.org/gtk3/stable/GtkCssProvider.html) and then customize your border and box-shadow with CSS. – elya5 May 30 '15 at 15:46
