XChangeDeviceDontPropagateList(3X11)XChangeDeviceDontPropagateList(3X11)NAME
XChangeDeviceDontPropagateList, XGetDeviceDontPropagateList - query or
change the dont-propagate-list for extension devices
SYNOPSIS
XChangeDeviceDontPropagateList(display, window, count, event_list,
mode)
Display *display;
Window *window;
int *count;
XEventClass *event_list;
int mode;
XEventClass *XGetDeviceDontPropagateList(display, window, count)
Display *display;
Window *window;
int *count;
ARGUMENTS
Specifies the connection to the X server. Specifies the window whose
dont-propagate-list is to be queried or modified. Specifies a pointer
to a list of event classes. Specifies the mode. You can pass
AddToList, or DeleteFromList. Specifies the number of event classes in
the list.
DESCRIPTION
The XChangeDeviceDontPropagateList request modifies the list of events
that should not be propagated to ancestors of the event window. This
request allows extension events to be added to or deleted from that
list. By default, all events are propagated to ancestor windows. Once
modified, the list remains modified for the life of the window. Events
are not removed from the list because the client that added them has
terminated.
Suppression of event propagation is not allowed for all input extension
events. If a specified event class is one that cannot be suppressed, a
BadClass error will result. Events that can be suppressed include
DeviceKeyPress, DeviceKeyRelease, DeviceButtonPress, DeviceButtonRe‐
lease, DeviceMotionNotify, ProximityIn, and ProximityOut.
XChangeDeviceDontPropagateList can generate a BadDevice, BadClass, or
BadValue error.
The XGetDeviceDontPropagateList request queries the list of events that
should not be propagated to ancestors of the event window.
XGetDeviceDontPropagateList can generate a BadClass or BadWindow error.
DIAGNOSTICS
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 some other client has caused the specified device to
become the X keyboard or X pointer device via the XChangeKeyboardDevice
or XChangePointerDevice requests. 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. An invalid window id was specified. An invalid
event class was specified.
