.SH DESCRIPTION
|
||
|
|
.LP
|
||
|
|
Actions associated with the XkbPtrAction structure move the pointer when keys
|
||
|
|
are pressed and released.
|
||
|
|
|
||
|
|
If the MouseKeys control is not enabled, KeyPress and KeyRelease events are
|
||
|
|
treated as though the action is XkbSA_NoAction.
|
||
|
|
|
||
|
|
If the MouseKeys control is enabled, a server action of type XkbSA_MovePtr
|
||
|
|
instructs the server to generate core pointer MotionNotify events rather than
|
||
|
|
the usual KeyPress event, and the corresponding KeyRelease event disables any
|
||
|
|
mouse keys timers that were created as a result of handling the XkbSA_MovePtr
|
||
|
|
action.
|
||
|
|
|
||
|
|
The
|
||
|
|
.I type
|
||
|
|
field of the XkbPtrAction structure is always XkbSA_MovePtr.
|
||
|
|
|
||
|
|
The
|
||
|
|
.I flags
|
||
|
|
field is a bitwise inclusive OR of the masks shown in Table 1.

XkbSA_NoAcceleration T{
|
||
|
|
If not set, and the MouseKeysAccel control is enabled, the KeyPress initiates a
|
||
|
|
mouse keys timer for this key; every time the timer expires, the cursor moves.
|
||
|
|
T}
|
||
|
|
XkbSA_MoveAbsoluteX T{
|
||
|
|
If set, the X portion of the structure specifies the new pointer X coordinate.
|
||
|
|
Otherwise, the X portion is added to the current pointer X coordinate to
|
||
|
|
determine the new pointer X coordinate.
|
||
|
|
T}
|
||
|
|
XkbSA_MoveAbsoluteY T{
|
||
|
|
If set, the Y portion of the structure specifies the new pointer Y coordinate.
|
||
|
|
Otherwise, the Y portion is added to the current pointer Y coordinate to
|
||
|
|
determine the new pointer Y coordinate.
|
||
|
|
T}
|
||
|
|
.TE
|
||
|
|
|
||
|
|
Each of the X and Y coordinantes of the XkbPtrAction structure is composed of
|
||
|
|
two signed 16-bit values, that is, the X coordinate is composed of
|
||
|
|
.I high_XXX
|
||
|
|
and
|
||
|
|
.I low_XXX,
|
||
|
|
and similarly for the Y coordinate. Xkb provides the following macros, to
|
||
|
|
convert between a signed integer and two signed 16-bit values in XkbPtrAction
|
||
|
|
structures.
