1XkbSetPtrActionY(3) XKB FUNCTIONS XkbSetPtrActionY(3)
2
6 XkbSetPtrActionY - Sets the high_YYY and low_YYY fields of act from the
7 signed integer value y
8
10 void XkbSetPtrActionY (XkbPtrAction act, int y);
11
13 - act action in which to set Y
14 - y new value to set
16
18 Actions associated with the XkbPtrAction structure move the pointer
19 when keys are pressed and released.
20 If the MouseKeys control is not enabled, KeyPress and KeyRelease events
22 are treated as though the action is XkbSA_NoAction.
23 If the MouseKeys control is enabled, a server action of type
25 XkbSA_MovePtr instructs the server to generate core pointer MotionNo‐
26 tify events rather than the usual KeyPress event, and the corresponding
27 KeyRelease event disables any mouse keys timers that were created as a
28 result of handling the XkbSA_MovePtr action.
29 The type field of the XkbPtrAction structure is always XkbSA_MovePtr.
31 The flags field is a bitwise inclusive OR of the masks shown in Table
33 1.

38 Action Type Meaning

40 XkbSA_NoAcceleration If not set, and the MouseKeysAccel con‐
41 trol is enabled, the KeyPress initiates
42 a mouse keys timer for this key; every
43 time the timer expires, the cursor
44 moves.
45 XkbSA_MoveAbsoluteX If set, the X portion of the structure
46 specifies the new pointer X coordinate.
47 Otherwise, the X portion is added to the
48 current pointer X coordinate to deter‐
49 mine the new pointer X coordinate.
50 XkbSA_MoveAbsoluteY If set, the Y portion of the structure
51 specifies the new pointer Y coordinate.
52 Otherwise, the Y portion is added to the
53 current pointer Y coordinate to deter‐
54 mine the new pointer Y coordinate.
55 Each of the X and Y coordinates of the XkbPtrAction structure is com‐
57 posed of two signed 16-bit values, that is, the X coordinate is com‐
58 posed of high_XXX and low_XXX, and similarly for the Y coordinate. Xkb
59 provides the following macros, to convert between a signed integer and
60 two signed 16-bit values in XkbPtrAction structures.
