ActionTool class
The ActionTool is responsible for handling and dispatching mouse events on GraphObjects that have GraphObject#isActionable set to true. This is how one implements "controls", such as buttons or sliders or knobs, as GraphObjects that can be inside Parts without interfering with the standard tool behaviors.
This tool allows individual GraphObjects (usually Panels) to handle mouse-down-move-up events without having to define new Tools. It does this by calling GraphObject#actionDown, GraphObject#actionMove, GraphObject#actionUp, and GraphObject#actionCancel on objects that have GraphObject#isActionable set to true.
This tool is a standard mouse-down tool, the ToolManager#actionTool.
This tool does not utilize any Adornments or tool handles. This tool does not modify the model or conduct any transaction, although the actions that this invokes may do so.
It would be very unusual to want to customize this tool.
