Inherited properties

Name Type Inherited from Description
description Accessor ReadOnly string ViewTool Get the localized description string from this Tool's class
description Accessor Static ReadOnly string ViewTool 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 ReadOnly string ViewTool 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 ViewTool Get the localized flyover string from this Tool's class
flyover Accessor Static ReadOnly string ViewTool 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 boolean ViewTool If true, this Tool will not appear in the list from getToolList.
iconSpec Accessor ReadOnly string ViewTool Get the iconSpec from this Tool's class.
inDynamicUpdate boolean ViewTool  
isControlDown Accessor ReadOnly boolean ViewTool Convenience method to check whether control key is currently down without needing a button event.
isDynamicsStarted Accessor ReadOnly boolean ViewTool Call to find out if dynamics are currently active.
keyin Accessor ReadOnly string ViewTool Get the localized keyin string from this Tool's class
keyin Accessor Static ReadOnly string ViewTool 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 ReadOnly undefined | number ViewTool 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 ReadOnly number ViewTool 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 string ViewTool The namespace that provides localized strings for this Tool.
receivedDownEvent boolean ViewTool Used to avoid sending tools up events for which they did not receive the down event.
toolId Accessor ReadOnly string ViewTool 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.
viewport ScreenViewport | undefined ViewTool
