Inherited properties

Name Type Inherited from Description
description Accessor ReadOnly string InteractiveTool Get the localized description string from this Tool's class
description Accessor StaticReadOnly 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,
InteractiveTool.flyover is returned.
englishKeyin Accessor StaticReadOnly 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 ReadOnly string InteractiveTool Get the localized flyover string from this Tool's class
flyover Accessor StaticReadOnly 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,
InteractiveTool.keyin is returned.
hidden Static boolean InteractiveTool If true, this Tool will not appear in the list from ToolRegistry.getToolList.
i18n Static I18N InteractiveTool The internationalization services instance used to translate strings from the namespace.
iconSpec Accessor ReadOnly string InteractiveTool Get the iconSpec from this Tool's class.
iconSpec Static string InteractiveTool The icon for this Tool.
isControlDown Accessor ReadOnly boolean InteractiveTool Convenience method to check whether control key is currently down without needing a button event.
isDynamicsStarted Accessor ReadOnly boolean InteractiveTool Call to find out if dynamics are currently active.
keyin Accessor ReadOnly string InteractiveTool Get the localized keyin string from this Tool's class
keyin Accessor StaticReadOnly 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 StaticReadOnly undefined | number InteractiveTool The maximum number of arguments allowed by InteractiveTool.parseAndRun, or undefined if there is no maximum.
If subclasses override InteractiveTool.parseAndRun, they should also override this method to indicate the maximum
number of arguments their implementation expects.
minArgs Accessor StaticReadOnly number InteractiveTool The minimum number of arguments allowed by InteractiveTool.parseAndRun. If subclasses override InteractiveTool.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 I18NNamespace InteractiveTool The I18NNamespace that provides localized strings for this Tool.
receivedDownEvent boolean InteractiveTool Used to avoid sending tools up events for which they did not receive the down event.
toolId Accessor 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 string InteractiveTool The unique string that identifies this tool.
