public virtual IList<IGoTool> MouseDownTools {get;}

Property Value

GoToolManager, an instance of which is normally the DefaultTool, iterates through this list when a mouse down event occurs. The first tool that it finds whose IGoTool.CanStart method returns true becomes this view's current Tool. If no such tool is found, the GoToolManager continues its normal behavior.

By default this returns a list containing instances of the GoToolAction, GoToolContext, GoToolPanning, GoToolRelinking, and GoToolResizing tools, in that order. The order of the tools matters, because even if several tools can start, only the first one actually is started.
