XSENDEXTENSIONEVENT(libmansuffix)
=================================
NAME
----
XSendExtensionEvent - send input extension events to a client
SYNOPSIS
--------
#include <X11/extensions/XInput.h>
Status XSendExtensionEvent( Display *display,
XDevice *device,
Window destination,
Bool propagate,
int event_count,
XEventClass *event_list,
XEvent *event_send);
display
Specifies the connection to the X server.
device
Specifies the device from which the events are to be
sent.
destination
Specifies the window the event is to be sent to. You can
pass window id, PointerWindow, or InputFocus.
propagate
Specifies a Boolean value that is either True or False.
event_count
Specifies the count of XEventClasses in event_list.
event_list
Specifies the list of event selections to be used.
event_send
Specifies a pointer to the event that is to be sent.
DESCRIPTION
-----------
The XSendExtensionEvent request identifies the destination
window, determines which clients should receive the specified
events, and ignores any active grabs. This request requires you
to pass an event class list. For a discussion of the valid
event class names, see XOpenDevice(libmansuffix) This
request uses the w argument to identify the destination window
as follows:
* If w is PointerWindow, the destination window is the window
that contains the pointer.
* If w is InputFocus and if the focus window contains the
pointer, the destination window is the window that contains
the pointer; otherwise, the destination window is the focus
window.
To determine which clients should receive the specified events,
XSendExtensionEvent uses the propagate argument as follows:
* If event_list is the empty set, the event is sent to the
client that created the destination window. If that client
no longer exists, no event is sent.
* If propagate is False, the event is sent to every client
selecting on destination any of the event types specified by
the event_list array.
* If propagate is True and no clients have selected on
destination any of the events specified by the event_list
array, the destination is replaced with the closest ancestor
of destination for which some client has selected a type
specified by the event-list array and for which no
intervening window has that type in
its do-not-propagate-mask. If no such window exists or if
the window is an ancestor of the focus window and
InputFocus was originally specified as the destination, the
event is not sent to any clients. Otherwise, the event is
reported to every client selecting on the final destination
any of the events specified in the event_list array.
The event in the XEvent structure must be one of the events
defined by the input extension (or a BadValue error results) so
that the X server can correctly byte-swap the contents as
necessary. The contents of the event are otherwise unaltered and
unchecked by the X server except to force send_event to True in
the forwarded event and to set the serial number in the event
correctly.
XSendExtensionEvent returns zero if the conversion to wire
protocol format failed and returns nonzero
otherwise. XSendExtensionEvent can generate BadClass, BadDevice,
BadValue, and BadWindow errors.
DIAGNOSTICS
-----------
BadDevice
An invalid device was specified. The specified device
does not exist or has not been opened by this client via
XOpenInputDevice. This error may also occur if the
specified device is the X keyboard or X pointer device.
BadValue
Some numeric value falls outside the range of values
accepted by the request. Unless a specific range is
specified for an argument, the full range defined by the
argument's type is accepted. Any argument defined as a
set of alternatives can generate this error.
BadWindow
A value for a Window argument does not name a defined
window.
