You do not normally need to create an instance of this tool because one already exists as the ToolManager.actionTool.
The Tool.name of this tool is "Action".
Optional init: Partial<ActionTool>VirtualOverridecanThis tool can run when there is a mouse-down on an object with GraphObject.isActionable true or if the object is within a Panel that "isActionable".
This method may be overridden. Please read the Introduction page on Extensions for how to override methods and how to call this base method.
OverridedoCall the GraphObject.actionCancel event if defined on the current object.
OverridedoIf there is a GraphObject found with GraphObject.isActionable set to true, call that object's GraphObject.actionDown event, if it exists.
OverridedoIf this tool is active call GraphObject.actionMove, if it exists, on the active object.
OverridedoCalls the GraphObject.actionUp event if defined, then effectively calls Tool.standardMouseClick to perform the normal click behaviors, and then stops this tool.
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.
