# 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.
