This section discusses the effects of explicitly changing indicators depending upon different settings in the indicator map. See Tables 1 and Table 2 for information on the effects of the indicator map fields when explicit changes are made.
If
XkbIM_LEDDrivesKB is set and XkbIM_NoExplicit is not, and if
you call a function that updates the server’s image of
the indicator map (such as XkbSetIndicatorMap or
XkbSetNamedIndicator),
Xkb changes the keyboard state and controls to reflect the
other fields of the indicator map. If you attempt to
explicitly change the value of an indicator for which
XkbIM_LEDDrivesKB is absent or for which XkbIM_NoExplicit is
present, keyboard state or controls are unaffected.
If neither XkbIM_NoAutomatic nor XkbIM_NoExplicit is set in an indicator map, Xkb honors any request to change the state of the indicator, but the new state might be immediately superseded by automatic changes to the indicator state if the keyboard state or controls change.
The effects of changing an indicator that drives the keyboard are cumulative; it is possible for a single change to affect keyboard group, modifiers, and controls simultaneously.
If you change an indicator for which both the XkbIM_LEDDrivesKB and XkbIM_NoAutomatic flags are specified, Xkb applies the keyboard changes specified in the other indicator map fields and changes the indicator to reflect the state that was explicitly requested. The indicator remains in the new state until it is explicitly changed again.
If the XkbIM_NoAutomatic flag is not set and XkbIM_LEDDrivesKB is set, Xkb applies the changes specified in the other indicator map fields and sets the state of the indicator to the values specified by the indicator map. Note that it is possible in this case for the indicator to end up in a different state than the one that was explicitly requested. For example, Xkb does not extinguish an indicator with which_mods of XkbIM_UseBase and mods of Shift if, at the time Xkb processes the request to extinguish the indicator, one of the Shift keys is physically depressed.
If you explicitly light an indicator for which XkbIM_LEDDrivesKB is set, Xkb enables all of the boolean controls specified in the ctrls field of its indicator map. Explicitly extinguishing such an indicator causes Xkb to disable all of the boolean controls specified in ctrls.
For each bit set in the which parameter, XkbSetIndicatorMap sends the corresponding indicator map from the desc parameter to the server.
