Inherited properties

Name	Type	Inherited from	Description
description Accessor Inherited ReadOnly	string	InteractiveTool	Get the localized description string from this Tool's class
description Accessor Static Inherited ReadOnly	string	InteractiveTool	Get the localized description for this Tool class. This returns the value of "tools." + this.toolId + ".description" from its registered Namespace (e.g. "en/MyApp.json"). If that key is not in the localization namespace, flyover is returned.
englishKeyin Accessor Static Inherited ReadOnly	string	InteractiveTool	Get the English keyin string for this Tool class. This returns the value of "tools." + this.toolId + ".keyin" from its registered Namespace (e.g. "en/MyApp.json").
flyover Accessor Inherited ReadOnly	string	InteractiveTool	Get the localized flyover string from this Tool's class
flyover Accessor Static Inherited ReadOnly	string	InteractiveTool	Get the localized flyover for this Tool class. This returns the value of "tools." + this.toolId + ".flyover" from its registered Namespace (e.g. "en/MyApp.json"). If that key is not in the localization namespace, keyin is returned.
hidden Static Inherited	boolean	InteractiveTool	If true, this Tool will not appear in the list from getToolList.
iconSpec Accessor Inherited ReadOnly	string	InteractiveTool	Get the iconSpec from this Tool's class.
iconSpec Static Inherited	string	InteractiveTool	The icon for this Tool.
isControlDown Accessor Inherited ReadOnly	boolean	InteractiveTool	Convenience method to check whether control key is currently down without needing a button event.
isDynamicsStarted Accessor Inherited ReadOnly	boolean	InteractiveTool	Call to find out if dynamics are currently active.
keyin Accessor Inherited ReadOnly	string	InteractiveTool	Get the localized keyin string from this Tool's class
keyin Accessor Static Inherited ReadOnly	string	InteractiveTool	Get the localized keyin string for this Tool class. This returns the value of "tools." + this.toolId + ".keyin" from its registered Namespace (e.g. "en/MyApp.json").
maxArgs Accessor Static Inherited ReadOnly	undefined | number	InteractiveTool	The maximum number of arguments allowed by parseAndRun, or undefined if there is no maximum. If subclasses override parseAndRun, they should also override this method to indicate the maximum number of arguments their implementation expects.
minArgs Accessor Static Inherited ReadOnly	number	InteractiveTool	The minimum number of arguments allowed by parseAndRun. If subclasses override parseAndRun, they should also override this method to indicate the minimum number of arguments their implementation expects. UI controls can use this information to ensure the tool has enough information to execute.
namespace Static Inherited	string	InteractiveTool	The namespace that provides localized strings for this Tool.
receivedDownEvent Inherited	boolean	InteractiveTool	Used to avoid sending tools up events for which they did not receive the down event.
toolId Accessor Inherited ReadOnly	string	InteractiveTool	Get the toolId string for this Tool class. This string is used to identify the Tool in the ToolRegistry and is used to localize the keyin, description, etc. from the current locale.
toolId Static Inherited	string	InteractiveTool	The unique string that identifies this tool.
