Public Methods

static	Copy(Event) : Event Copies a Gdk.Event.
static	Free(Event) Frees a Gdk.Event.
static	Get() : Event Checks all open displays for a Gdk.Event to process, fetching events from the windowing system if necessary. See Display.Event.
static	GetAxis(Event, AxisUse, out double) : bool Extract the axis value for a particular axis use from an event.
static	GetCoords(Event, out double, out double) : bool Extract the event window relative x/y coordinates from an event.
static	GetGraphicsExpose(Window) : Event Waits for a GraphicsExpose or NoExpose event from the X server. This is used in the GtkText and GtkCList widgets in Gtk# to make sure any Graphics Expose events are handled before the widget is scrolled.
static	GetRootCoords(Event, out double, out double) : bool Extract the root window relative x/y coordinates from an event.
static	GetScreen(Event) : Screen Returns the screen for the event. The screen is typically the screen for Event.Window, but for events such as mouse events, it is the screen where the pointer was when the event occurs.
static	GetState(Event, out ModifierType) : bool If the event contains a "state" field, puts that field in state. Otherwise stores an empty state (0).
static	GetTime(Event) : uint Returns the time stamp from event, if there is one. Otherwise returns the current time. If event is null, returns the current time..
static	New(EventType) : Event Creates a new event of the given type. All fields are set to 0.
static	Peek() : Event If there is an event waiting in the event queue of some open display, returns a copy of it. See Display.PeekEvent.
static	Put(Event) Appends a copy of the given event onto the front of the event queue for Event.Window's display, or the default queue if that window is null. See Display.PutEvent.
static	RequestMotions(EventMotion) Requests additional motion notify events.
static	SendClientMessage(Event, uint) : bool Sends an X ClientMessage event to a given window (which must be on the default Gdk.Display.) This could be used for communicating between different applications, though the amount of data is limited to 20 bytes.
static	SendClientMessageForDisplay(Display, Event, uint) : bool 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.
static	SendClientmessageToall(Event) Sends an X ClientMessage event to all toplevel windows on the default Gdk.Screen. 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.
static	SetScreen(Event, Screen) Sets the screen for event to screen. The event must have been allocated by GTK+, for instance, by EventHelper.Copy.
