Защищенные методы

Метод	Описание
ClearObjects ( ) : void	Clears the objects.
CursorMoved ( Point coords ) : void	Called when the cursor is being moved. Highlights objects when the cursor passes over them.
Dispose ( bool disposing ) : void
GetSelection ( Point coords, bool inMotion = false, bool skipSelected = false ) : Selection
HandleLeftButton ( Point coords, ButtonModifier modif ) : void
HandleMotionEvent ( Point coords ) : void
HandleRightButton ( Point coords, ButtonModifier modif ) : void
SelectionChanged ( List sel ) : void	Notifies subclasses when the selected objects has changed.
SelectionMoved ( Selection sel ) : void	Notifies subclasses when an object has been moved.
ShowMenu ( Point coords ) : void	Notifies subclasses a menu should be displayed. Canvas' with menus should override it to display their menu here.
StartMove ( Selection sel ) : void	Notifies subclasses when an object starts to be moved.
StopMove ( bool moved ) : void	Notifies subclass when the move process stops.
UpdateSelection ( Selection sel, bool notify = true ) : void	Updates the current selection. If sel is `null`, it clears the current selection. If sel wasn't previously selected, it's added to the list of selected objects, otherwise it's removed from the list.
