XkbSAActionSetCtrls - Sets the ctrls0 through ctrls3 fields of act from ctrls

void XkbSAActionSetCtrls ( XkbCtrlsAction */act/ ,* unsigned int */ctrls/ );*

- act

action in which to set ctrls0-ctrls3

- ctrls

value to set in ctrls0-ctrls3

Actions associated with the XkbCtrlsAction structure change the state of the boolean controls.

The type field can have any one of the values shown in Table 1.

TABLE

The flags field is composed of the bitwise inclusive OR of the masks shown in Table 2.

TABLE

The XkbSA_SetControls action implements a key that enables a boolean control when pressed and disables it when released. The XkbSA_LockControls action is used to implement a key that toggles the state of a boolean control each time it is pressed and released. The XkbSA_LockNoLock and XkbSA_LockNoUnlock flags allow modifying the toggling behavior to only unlock or only lock the boolean control.

The ctrls0, ctrls1, ctrls2, and ctrls3 fields represent the boolean controls in the enabled_ctrls field of the controls structure. Xkb macros, to convert between the two formats.

XkbSAActionSetCtrls sets the ctrls0 through ctrls3 fields of act from ctrls.
