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
|
2011-07-02 15:21:11 -06:00
|
|
|
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 struct {

|
|
|
|
|
|
|
|
|
|
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
