I would like to have my buttons, when toggled, to have a 3D bevelled look, as in the below image, created with Powerpoint:
Is this possible? In GTK4 the ShadowType and Relief properties have been removed, and it is recommended to use gtk_button_set_has_frame(). I tried this on my button with a CSS image background and it made no difference. Nor does setting the boolean frame value give me any hints as to how to edit and manipulate the frame itself.
Using css properties like box-shadow: inset or border-style: groove I can add a more bevel like feel, but the transform property does not appear to have a pressed-in feature as in my above image.
