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 Specification. You can find this specification on http://www.freedesktop.org.

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 gdk_x11_screen_supports_net_wm_hint() will return FALSE for every property. You can monitor the window_manager_changed signal on GdkScreen to detect a window manager change.

The application can use this call to update the _NET_WM_USER_TIME property on a toplevel window. This property stores an Xserver time which represents the time of the last user input event received for this window. This property may be used by the window manager to alter the focus, stacking, and/or placement behavior of windows when they are mapped depending on whether the new window was created by a user action or is a "pop-up" window activated by a timer or some other event.

Note that this property is automatically updated by GDK, so this function should only be used by applications which handle input events bypassing GDK.

                                             gint n_events);

Registers interest in receiving extension events with type codes between event_base and event_base + n_events - 1. The registered events must have the window field in the same place as core X events (this is not the case for e.g. XKB extension events).

If an event type is registered, events of this type will go through global and window-specific filters (see gdk_window_add_filter()). Unregistered events will only go through global filters. GDK may register the events of some X extensions on its own.

This function should only be needed in unusual circumstances, e.g. when filtering XInput extension events on the root window.
