On X11, sends an X ClientMessage event to a given window. On Windows, sends a message registered with the name GDK_WIN32_CLIENT_MESSAGE. This could be used for communicating between different applications, though the amount of data is limited to 20 bytes on X11, and to just four bytes on Windows.

The for the window where the message is to be sent. The to send, which should be a . The window to send the client message to. True on success. None. Method System.Void

Frees a .

to free. This should only be called with events returned from functions such as , , and . Method System.Void

Sends an X ClientMessage event to all toplevel windows on the default . Toplevel windows are determined by checking for the WM_STATE property, as described in the Inter-Client Communication Conventions Manual (ICCCM). If no windows are found with the WM_STATE property set, the message is sent to all children of the root window.

The to send, which should be a . None. Method System.Boolean

This constructor is never used.

This class contains only static methods, and this constructor should never be used. Method System.Boolean

Extract the event window relative x/y coordinates from an event.

A Event window x coordinate. Event window y coordinate. True if the event delivered event coordinates. None. Method System.Boolean

If the event contains a "state" field, puts that field in state. Otherwise stores an empty state (0).

A or null. The of the event. True if there was a state field in the event. To be added Method System.Boolean

Extract the axis value for a particular axis use from an event.

A The axis use to look for. The value found. True if the specified axis was found, otherwise false. None. Method System.Boolean

Extract the root window relative x/y coordinates from an event.

A Root window x coordinate. Root window y coordinate. True if the event delivered root window coordinates. None. Property GLib.GType

GType Property.

a Returns the native value for . Method System.Void A MotionNotify event.

Requests additional motion notify events.
