GdkX11.X11Screen.prototype.supports_net_wm_hint

function supports_net_wm_hint(property: Gdk.Atom): Boolean {
    // Gjs wrapper for gdk_x11_screen_supports_net_wm_hint()
}
  

This function is specific to the X11 backend of GDK, and indicates whether the window manager supports a certain hint from the [Extended Window Manager Hints](http://www.freedesktop.org/Standards/wm-spec) specification.

When using this function, keep in mind that the window manager can change over time; so you shouldn’t use this function in a way that impacts persistent application state. A common bug is that your application can start up before the window manager does when the user logs in, and before the window manager starts GdkX11.X11Screen.prototype.supports_net_wm_hint will return false for every property. You can monitor the window_manager_changed signal on Gdk.Screen to detect a window manager change.
