set_opacity


Description:

[ Version ( deprecated = true , since = "2.12" , deprecated_since = "3.8" ) ]
public void set_opacity (double opacity)

Warning: set_opacity is deprecated since "3.8".

Request the windowing system to make this partially transparent, with opacity 0 being fully transparent and 1 fully opaque.

Note:

Use gtk_widget_set_opacity instead.

(Values of the opacity parameter are clamped to the [0,1] range.) On X11 this has any effect only on X screens with a compositing manager running. See is_composited. On Windows it should work always.

Note that setting a window’s opacity after the window has been shown causes it to flicker once on Windows.

Parameters:

this

a Window

opacity

desired opacity, between 0 and 1
