goog.ui.equation.PaletteManager()
Constructs the palette manager that manages all the palettes in Equation Editor.
.addEventListener(type, handler, opt_capture, opt_handlerScope)
Inherited from goog.events.EventTarget
.
Adds an event listener to the event target. The same handler can only be added once per the type. Even if you add the same handler multiple times using the same type then it will only be called once when the event is dispatched. Supported for legacy but use goog.events.listen(src, type, handler) instead.

.addOnDisposeCallback(callback, opt_scope)
Inherited from goog.Disposable
.
Invokes a callback function when this object is disposed. Callbacks are invoked in the order in which they were added.

opt_scope

.creationStack
{string
}Inherited from goog.Disposable
.
If monitoring the goog.Disposable instances is enabled, stores the creation stack trace of the Disposable instance.
.deactivate()
Starts the deactivation of open palette. This method has a slight delay before doing the real deactivation. This helps prevent sudden disappearing of palettes when user moves mouse outside them just briefly (and maybe accidentally). If you really want to deactivate the active palette, use {@link #deactivateNow()} instead.
.deactivateNow()
Deactivate the open palette immediately.
.dispatchEvent(e)
Inherited from goog.events.EventTarget
.
Dispatches an event (or event like object) and calls all listeners listening for events of this type. The type of the event is decided by the type property on the event object. If any of the listeners returns false OR calls preventDefault then this function will return false. If one of the capture listeners calls stopPropagation, then the bubble listeners won't fire.

.dispose()
Inherited from goog.Disposable
.
Disposes of the object. If the object hasn't already been disposed of, calls {@link #disposeInternal}. Classes that extend {@code goog.Disposable} should override {@link #disposeInternal} in order to delete references to COM objects, DOM nodes, and other disposable objects. Reentrant.
void
}
.disposeInternal()
[protected]Unattach listeners from this object. Classes that extend EventTarget may need to override this method in order to remove references to DOM Elements and additional listeners, it should be something like this:
MyClass.prototype.disposeInternal = function() { MyClass.superClass_.disposeInternal.call(this); // Dispose logic for MyClass };
.getActive()
Returns the active palette.

Returns the parent of this event target to use for bubbling.

.registerDisposable(disposable)
Inherited from goog.Disposable
.
Associates a disposable object with this object so that they will be disposed together.

{goog.disposable.IDisposable
}
.removeEventListener(type, handler, opt_capture, opt_handlerScope)
Inherited from goog.events.EventTarget
.
Removes an event listener from the event target. The handler must be the same object as the one added. If the handler has not been added then nothing is done.

.setActive(type)
Sets the palette instance of given type to be the active one.
type

.setParentEventTarget(parent)
Inherited from goog.events.EventTarget
.
Sets the parent of this event target to use for bubbling.
parent

.stopDeactivation()
Clears the deactivation timer. This is used to prevent palette manager deactivation when mouse pointer is moved outside palettes and moved back quickly inside a grace period.
