XChangeDeviceDontPropagateList(3X1X)FUNCTIXChangeDeviceDontPropagateList(3X11)NAME
XChangeDeviceDontPropagateList, XGetDeviceDontPropagateList - query or
change the dont-propagate-list for extension devices
SYNTAX
int XChangeDeviceDontPropagateList(Display *display, Window *window,
int *count, XEventClass *event_list, int mode);
XEventClass *XGetDeviceDontPropagateList(Display *display, Window *win‐
dow, int *count);
ARGUMENTS
display Specifies the connection to the X server.
window Specifies the window whose dont-propagate-list is to be
queried or modified.
event_list Specifies a pointer to a list of event classes.
mode Specifies the mode. You can pass AddToList , or Delete‐
FromList.
count 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
BadDevice An invalid device was specified. The specified device does
not exist or has not been opened by this client via XOpen‐
InputDevice. This error may also occur if some other
client has caused the specified device to become the X key‐
board or X pointer device via the XChangeKeyboardDevice or
XChangePointerDevice requests.
BadValue Some numeric value falls outside the range of values
accepted by the request. Unless a specific range is speci‐
fied for an argument, the full range defined by the argu‐
ment's type is accepted. Any argument defined as a set of
alternatives can generate this error.
BadWindow An invalid window id was specified.
BadClass An invalid event class was specified.
