- * gdk_surface_set_opacity:
- * @surface: a top-level or non-native #GdkSurface
- * @opacity: opacity
- *
- * Set @surface to render as partially transparent,
- * with opacity 0 being fully transparent and 1 fully opaque. (Values
- * of the opacity parameter are clamped to the [0,1] range.) 
- *
- * For toplevel surfaces this depends on support from the windowing system
- * that may not always be there. For instance, On X11, this works only on
- * X screens with a compositing manager running. On Wayland, there is no
- * per-surface opacity value that the compositor would apply. Instead, use
- * `gdk_surface_set_opaque_region (surface, NULL)` to tell the compositor
- * that the entire surface is (potentially) non-opaque, and draw your content
- * with alpha, or use gtk_widget_set_opacity() to set an overall opacity
- * for your widgets.
- *
- * Support for non-toplevel surfaces was added in 3.8.
