EditManipulator.HandleTool Class

Interactive control handle modification is done by installing an InputCollector. Modification typically is started from a click or press and drag while over the handle graphics. The HandleTool base class is set up to define an offset by 2 points. The second point is defined by either another click, or up event when initiated from press and drag.

Inherited properties

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