XChangeDeviceDontPropagateList, XGetDeviceDontPropagateList - query or
change the dont-propagate-list for extension devices
SYNTAX
#include <X11/extensions/XInput.h>
int XChangeDeviceDontPropagateList(Display *display, Window*window,
int *count, XEventClass *event_list,
intmode);
XEventClass* XGetDeviceDontPropagateList(Display *display,
Window *window, 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 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.
