XkbSetControls(3) XKB FUNCTIONS XkbSetControls(3) NAME XkbSetControls - Copies changes to the X server based on a modified ctrls structure in a local copy of the keyboard description SYNOPSIS Bool XkbSetControls (Display *display, unsigned long which, XkbDescPtr xkb); ARGUMENTS display connection to X server which mask of controls requested xkb keyboard description for controls information DESCRIPTION For each bit that is set in the which parameter, XkbSetControls sends the corresponding values from the xkb->ctrls field to the server. Valid values for which are any combination of the masks listed in Table 1 that have "ok" in the which column. Table 1 shows the actual values for the individual mask bits used to select controls for modification and to enable and disable the control. Note that the same mask bit is used to specify general modifications to the parame- ters used to configure the control (which), and to enable and disable the control (enabled_ctrls). The anomalies in the table (no "ok" in column) are for controls that have no configurable attributes; and for controls that are not boolean controls and therefore cannot be enabled or disabled. c s s s l l l l l l l l l l l l.

Otherwise, it sends the request to the X server and returns True. Note that changes to attributes of controls in the XkbControlsRec structure are apparent only when the associated control is enabled, although the cor- responding values are still updated in the X server. For example, the re- peat_delay and repeat_interval fields are ignored unless the RepeatKeys control is enabled (that is, the X server's equivalent of xkb->ctrls has XkbRepeatKeyMask set in enabled_ctrls). It is permissible to modify the attributes of a control in one call to XkbSetControls and enable the con- trol in a subsequent call. See XkbChangeEnabledControls for more informa- tion on enabling and disabling controls. Note that the enabled_ctrls field is itself a control - the EnabledControls control. As such, to set a specific configuration of enabled and disabled boolean controls, you must set enabled_ctrls to the appropriate bits to en- able only the controls you want and disable all others, then specify the XkbControlsEnabledMask in a call to XkbSetControls. Because this is somewhat awkward if all you want to do is enable and dis- able controls, and not modify any of their attributes, a convenience func- tion is also provided for this purpose, XkbChangeEnabledControls. RETURN VALUES True The XkbSetControls function returns True when it sends the request to the X server. False The XkbSetControls function returns False when xkb->ctrls is NULL, the server does not support a compatible version of Xkb, or the Xkb extension has not been properly initialized. DIAGNOSTICS BadAlloc Unable to allocate storage BadMatch A compatible version of Xkb was not available in the server or an argument has correct type and range, but is otherwise invalid SEE ALSO XkbChangeEnabledControls(3), XkbFreeControls(3) X Version 11 libX11 1.8.13 XkbSetControls(3)
