XChangeDeviceDontPropagateList(3) X FUNCTIONS XChangeDeviceDontPropagateList(3)
XChangeDeviceDontPropagateList, XGetDeviceDontPropagateList - query or change the dont-
propagate-list for extension devices
int XChangeDeviceDontPropagateList(Display *display, Window *window, int *count, XEvent-
Class *event_list, int mode);
XEventClass *XGetDeviceDontPropagateList(Display *display, Window *window, int *count);
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 DeleteFromList.
count Specifies the number of event classes in the list.
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,
DeviceButtonRelease, 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.
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 some other client has caused the specified device to become the X
keyboard or X pointer device via the XChangeKeyboardDevice or XChangePointer-
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 alterna-
tives can generate this error.
BadWindow An invalid window id was specified.
BadClass An invalid event class was specified.
