NAME

XChangeDeviceDontPropagateList, XGetDeviceDontPropagateList - query or change the dont-propagate-list for extension devices

SYNOPSIS

#include <X11/extensions/XInput.h>

int XChangeDeviceDontPropagateList( Display *display,


                                    Window window,


                                    int count,


                                    XEventClass *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.

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, 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.

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 some


       other client has caused the specified device to become


       the X keyboard 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


       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


       An invalid window id was specified.

BadClass


       An invalid event class was specified.
