DIAGNOSTICS
XChangeDeviceDontPropagateList, XGetDeviceDontPropagateList − query or change the dont−propagate−list for extension devices
#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.
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 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.
