XKB FUNCTIONS XkbSetControls(3x11)
NAME
XkbSetControls - Copies changes to the X server based on a
modified ctrls structure in a local copy of the keyboard descriptionSYNOPSIS

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 informationDESCRIPTION
For each bit that is set in the which parameter, XkbSetCon-
trols sends the corresponding values from the xkb->ctrls
field to the server. Valid values for which are any combina-
tion 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 tospecify general modifications to the parameters used to con-
figure the control (which), and to enable and disable thecontrol (enabled_ctrls). The anomalies in the table (no "ok"
in column) are for controls that have no configurable attri-
butes; and for controls that are not boolean controls and therefore cannot be enabled or disabled. Table 1 Controls Mask Bits__________________________________________________________________________

tible version of Xkb, or the Xkb extension has not beenproperly initialized, XkbSetControls returns False. Other-
wise, it sends the request to the X server and returns True.Note that changes to attributes of controls in the XkbCon-
trolsRec structure are apparent only when the associated control is enabled, although the corresponding values arestill updated in the X server. For example, the repeat_delay
and repeat_interval fields are ignored unless the RepeatKeys
control is enabled (that is, the X server's equivalent ofxkb->ctrls has XkbRepeatKeyMask set in enabled_ctrls). It is
permissible to modify the attributes of a control in onecall to XkbSetControls and enable the control in a subse-
quent 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 confi-
guration of enabled and disabled boolean controls, you mustset enabled_ctrls to the appropriate bits to enable only the
controls you want and disable all others, then specify theXkbControlsEnabledMask in a call to XkbSetControls.
Because this is somewhat awkward if all you want to do is enable and disable controls, and not modify any of their attributes, a convenience function 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 theXkb extension has not been properly initial-
ized. X Version 11 Last change: libX11 1.3.5 2XKB FUNCTIONS XkbSetControls(3x11)
