XkbSASetPtrDfltValue(3) XKB FUNCTIONS XkbSASetPtrDfltValue(3) NAME
XkbSASetPtrDfltValue - Sets the valueXXX field of act from val SYNOPSIS
void XkbSASetPtrDfltValue macro ( act, val ) XkbAction act; int val; ARGUMENTS
- act action in which to set valueXXX - val value to set in valueXXX DESCRIPTION
Actions associated with the XkbPtrDfltAction structure change the mk_dflt_btn attribute of the MouseKeys control. If the MouseKeys control is not enabled, KeyPress and KeyRelease events are treated as though the action is XkbSA_NoAction. Otherwise, this action changes the mk_dflt_btn attribute of the MouseKeys control. The type field of the XkbPtrDfltAction structure should always be XkbSA_SetPtrDflt. The flags field is composed of the bitwise inclusive OR of the values shown in Table 1 (currently there is only one value defined). Table 1 Pointer Default Flags ----------------------------------------------------------------- Flag Meaning ----------------------------------------------------------------- XkbSA_DfltBtnAbsolute If set, the value field represents an absolute pointer button. Otherwise, the value field represents the amount to be added to the current default button. The affect field specifies what changes as a result of this action. The only valid value for the affect field is XkbSA_AffectDfltBtn. The valueXXX field is a signed character that represents the new button value for the mk_dflt_btn attribute of the MouseKeys control. If XkbSA_DfltBtnAbsolute is set in flags, valueXXX specifies the button to be used; otherwise, valueXXX specifies the amount to be added to the current default button. In either case, illegal button choices are wrapped back around into range. Xkb provides macros, to convert between the integer and signed character values in XkbPtrDfltAction structures. STRUCTURES

XkbSetPtrActionY(3) XKB FUNCTIONS XkbSetPtrActionY(3) NAME
XkbSetPtrActionY - Sets the high_YYY and low_YYY fields of act from the signed integer value y SYNOPSIS
void XkbSetPtrActionY macro ( act, y ) XkbPtrAction act; int y; ARGUMENTS
- act action in which to set Y - y new value to set DESCRIPTION
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 type field of the XkbPtrAction structure is always XkbSA_MovePtr. The flags field is a bitwise inclusive OR of the masks shown in Table 1. Table 1 Pointer Action Types ---------------------------------------------------------------- Action Type Meaning ---------------------------------------------------------------- XkbSA_NoAcceleration If not set, and the MouseKeysAccel con- trol is enabled, the KeyPress initiates a mouse keys timer for this key; every time the timer expires, the cursor moves. XkbSA_MoveAbsoluteX 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 deter- mine the new pointer X coordinate. XkbSA_MoveAbsoluteY 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 deter- mine the new pointer Y coordinate. 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 com- posed of high_XXX and 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. STRUCTURES
