XICHANGEHIERARCHY(3)													      XICHANGEHIERARCHY(3)

NAME

       XIChangeHierarchy - change the device hierarchy.

SYNOPSIS

       #include <X11/extensions/XInput2.h>

       Status XIChangeHierarchy( Display *display,
				 XIAnyHierarchyChangeInfo *changes,
				 int num_changes);

       display
	      Specifies the connection to the X server.

       num_changes
	      Specifies the number of elements in changes.

       changes
	      Specifies the changes to be made.

DESCRIPTION

	   XIChangeHierarchy modifies the device hierarchy by creating or
	   removing master devices or changing the attachment of slave
	   devices. If num_changes is non-zero, changes is an array of
	   XIAnyHierarchyChangeInfo structures. If num_changes is equal or less than
	   zero, XIChangeHierarchy does nothing.

	   XIChangeHierarchy processes changes in order, effective
	   immediately. If an error occurs, processing is aborted and the
	   error is reported to the client. Changes already made remain
	   effective.

	   The list of changes is any combination of
	   XIAnyHierarchyChangeInfo. The type of a hierarchy change can be
	   XIAddMaster, XIRemoveMaster, XIAttachSlave or XIDetachSlave.

	   typedef union {
	       int type;
	       XIAddMasterInfo add;
	       XIRemoveMasterInfo remove;
	       XIAttachSlave attach;
	       XIDetachSlave detach;
	   } XIAnyHierarchyChangeInfo;

	   typedef struct {
	       int type; /* XIAddMaster */
	       char* name;
	       Bool send_core;
	       Bool enable;
	   } XIAddMasterInfo;

	   typedef struct {
	       int type; /* XIRemoveMaster */
	       int deviceid;
	       int return_mode;
	       int return_pointer;
	       int return_keyboard;
	   } XIRemoveMasterInfo;

	   typedef struct {
	       int type; /* XIAttachSlave */
	       int deviceid;
	       int new_master;
	   } XIAttachSlaveInfo;

	   typedef struct {
	       int type; /* XIDetachSlave */
	       int deviceid;
	   } XIDetachSlaveInfo;

	   XIAddMasterInfo creates a new master pointer and a new
	   master keyboard labelled "name pointer" and "name keyboard"
	   respectively. If sendCore is True, the devices will send core
	   events. If enable is True, the device is enabled immediately.

	   XIAddMasterInfo can generate a BadValue error.

	   XIRemoveMasterInfo removes device and its paired master device.
	   If returnMode is XIAttachToMaster, all pointers attached to
	   device or its paired master device are attached to
	   returnPointer. Likewise, all keyboards are attached to
	   returnKeyboard. If returnMode is XIFloating, all attached
	   devices are set to floating.

	   XIRemoveMasterInfo can generate a BadValue and a BadDevice
	   error.

	   XIAttachSlaveInfo attaches device to newMaster. If the device
	   is currently attached to a master device, it is detached from
	   the master device and attached to the new master device.

	   XIAttachSlaveInfo can generate a BadDevice error.

	   XIDettachSlaveInfo deattaches device from the current master
	   device and sets it floating. If the device is already floating,
	   no changes are made.

	   XIDetachSlaveInfo can generate a BadDevice error.

	   XIChangeHierarchy generates an XIHierarchyEvent if any
	   modifications were successful.

DIAGNOSTICS

	   BadDevice
		  An invalid device was specified. The device does not
		  exist or is not a appropriate for the type of change.

	   BadValue
		  Some numeric value falls out of the allowed range.

XISETFOCUS(3)															     XISETFOCUS(3)

NAME

       XISetFocus, XIGetFocus - set or get the device's focus.

SYNOPSIS

       #include <X11/extensions/XInput2.h>

       Status XISetFocus( Display *display,
			  int deviceid,
			  Window focus,
			  Time time);

       Status XIGetFocus( Display *display,
			  Window *focus_return);

       display
	      Specifies the connection to the X server.

       deviceid
	      Specifies the device whose focus is to be queried or
	      changed.

       focus
	      The new focus window.

       focus_return
	      Returns the current focus window.

       time
	      A valid timestamp or CurrentTime.

DESCRIPTION

	   XISetFocus changes the focus of the specified device ans its
	   last-focus-change time. It has no effect if the specified time
	   is earlier than the current last-focus-change time or is later
	   than the current X server time. Otherwise, the
	   last-focus-change time is set to the specified time.
	   CurrentTime is replaced by the current X server time).
	   XISetFocus causes the X server to generate core, XI and XI2
	   focus events.

	   If the focus window is None all keyboard events by this device
	   are discarded until a new focus window is set. Otherwise, if
	   focus is a window, it becomes the device's focus window. If a
	   generated device event would normally be reported to this
	   window or one of its inferiors, the event is reported as usual.
	   Otherwise, the event is reported relative to the focus window.

	   The specified focus window must be viewable at the time
	   XISetFocus is called, or a BadMatch error results. If the focus
	   window later becomes not viewable, the focus reverts to the
	   parent (or the closest viewable ancestor. When the focus
	   reverts, the X server generates core, XI and XI2 focus events
	   but the last-focus-change time is not affected.

	   Attempting to set the focus on a master pointer device or an
	   attached slave device will result in a BadDevice error.

	   XISetFocus can generate BadDevice, BadMatch, BadValue, and
	   BadWindow errors.

DIAGNOSTICS

	   BadValue
		  A value is outside of the permitted range.

	   BadDevice
		  An invalid device was specified. The device does not
		  exist or is not a appropriate for the type of change.

	   BadMatch
		  The window is not viewable.

	   BadWindow
		  A value for a Window argument does not name a defined
		  Window.
