NAME
XkbSASetPtrDfltValue - Sets the valueXXX field of act from val
SYNOPSIS
void XkbSASetPtrDfltValue (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.
