XkbActionCtrls(3) XKB FUNCTIONS XkbActionCtrls(3) NAME XkbActionCtrls - Returns the ctrls fields of act converted to an unsigned int SYNOPSIS unsigned int XkbActionCtrls (XkbCtrlsAction act); ARGUMENTS act action from which to extract controls DESCRIPTION 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 1 Controls Action Types -------------------------------------------------------------- Type Effect -------------------------------------------------------------- XkbSA_SetControls A key press enables any boolean controls specified in the ctrls fields that were not already enabled at the time of the key press. A key release disables any controls enabled by the key press. This action can cause XkbControlsNotify events. XkbSA_LockControls If the XkbSA_LockNoLock bit is not set in the flags field, a key press enables any controls specified in the ctrls fields that were not already enabled at the time of the key press. If the XkbSA_LockNoUnlock bit is not set in the flags field, a key release dis- ables any controls specified in the ctrls fields that were not already dis- abled at the time of the key press. This action can cause XkbControlsNotify events. The flags field is composed of the bitwise inclusive OR of the masks shown in Table 2. Table 2 Control Action Flags -------------------------------------------------------------- Flag Meaning -------------------------------------------------------------- XkbSA_LockNoLock If set, and the action type is XkbSA_LockControls, the server only dis- ables controls. XkbSA_LockNoUnlock If set, and the action type is XkbSA_LockControls, the server only en- ables controls. The XkbSA_SetControls action implements a key that enables a boolean con- trol when pressed and disables it when released. The XkbSA_LockControls ac- tion 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_Lock- NoUnlock 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 con- trols in the enabled_ctrls field of the controls structure. Xkb macros, to convert between the two formats. XkbActionCtrls returns the ctrls fields of act converted to an unsigned int.
