Description

Creates and manages the Chrome container which holds all of the Cinnamon UI actors.

Functions

updateChrome ()


updateChrome (boolean   doVisibility);

Updates input region and struts for all chrome actors. If doVisibility is true, then the visibility state of all chrome actors is recalculated first.

Use with care as this is already frequently updated, and can reduce performance if called unnecessarily.

Parameters

doVisibility

(optional) whether to recalculate visibility.

addChrome ()


addChrome (Clutter.Actor   actor,
           object          params);

Adds actor to the chrome, and (unless affectsInputRegion in params is false) extends the input region to include it. Changes in actor's size, position, and visibility will automatically result in appropriate changes to the input region.

If affectsStruts in params is true (and actor is along a screen edge), then actor's size and position will also affect the window manager struts. Changes to actor's visibility will NOT affect whether or not the strut is present, however.

If visibleInFullscreen in params is true, the actor will be visible even when a fullscreen window should be covering it.

Parameters

actor	an actor to add to the chrome
params	(optional) additional params visibleInFullcreen (boolean): The actor should be hidden when a window on the same monitor is fullscreen. Default `false`. affectsStruts (boolean): The actor's allocation should be used to add window manager struts. Default `false`. affectsInputRegion (boolean): The actor should be added to the stage input region. Default `true`. addToWindowgroup (boolean): The actor should be added as a top-level window. Default `false`. doNotAdd (boolean): The actor should not be added to the uiGroup. This has no effect if `addToWindowgroup` is `true`. Default `false`.

trackChrome ()


trackChrome (Clutter.Actor   actor,
             object          params);

Tells the chrome to track actor, which must be a descendant of an actor added via addChrome(). This can be used to extend the struts or input region to cover specific children.

params can have any of the same values as in addChrome(), though some possibilities don't make sense (eg, trying to have a visibleInFullscreen child of a non-visibleInFullscreen parent).

Parameters

actor	a descendant of the chrome to begin tracking
params	(optional) additional params - defaults to same as chrome ancestor visibleInFullcreen (boolean): The actor should be hidden when a window on the same monitor is fullscreen. affectsStruts (boolean): The actor's allocation should be used to add window manager struts. affectsInputRegion (boolean): The actor should be added to the stage input region. addToWindowgroup (boolean): The actor should be added as a top-level window. doNotAdd (boolean): The actor should not be added to the uiGroup. This has no effect if `addToWindowgroup` is `true`.

untrackChrome ()


untrackChrome (Clutter.Actor   actor);

Undoes the effect of trackChrome()

Parameters

actor

an actor previously tracked via trackChrome()

removeChrome ()

boolean
isTrackingChrome (Clutter.Actor   actor);

Determines whether the actor is currently tracked or not.
