Methods

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
addObject(DrawObject object) → void: Calling this will notify all the listeners of this WindowPaintController that they need to update (it calls notifyListeners()). For this reason, this value should only be set between frames, e.g. in response to user actions, not during the build, layout, or paint phases.
addObjects(Iterable<DrawObject> objects) → void: Calling this will notify all the listeners of this WindowPaintController that they need to update (it calls notifyListeners()). For this reason, this value should only be set between frames, e.g. in response to user actions, not during the build, layout, or paint phases.
cancelSelectObject() → void: Restores color to the value it had before the object was selected.
dispose() → void: Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
objectWasUpdated() → void: Calling this will notify all the listeners of this WindowPaintController that the last object is done. This is basically just a wrapper around notifyListeners().
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
removeObject(DrawObject object) → void: Calling this will notify all the listeners of this WindowPaintController that they need to update (it calls notifyListeners()). For this reason, this value should only be set between frames, e.g. in response to user actions, not during the build, layout, or paint phases.
removeObjectsWhere(bool test(DrawObject object)) → void: Calling this will notify all the listeners of this WindowPaintController that they need to update (it calls notifyListeners()). For this reason, this value should only be set between frames, e.g. in response to user actions, not during the build, layout, or paint phases.
selectObject(int index) → void: Stores the color so that it can be restored when the selection gets cancelled.
toString() → String: A string representation of this object.

Operators

operator ==(Object other) → bool: The equality operator.
