Inherited properties

Name Type Inherited from Description
_useViewAlignedVolume ProtectedStatic boolean ViewManip  
description Accessor ReadOnly string Tool Get the localized description string from this Tool's class
description Accessor StaticReadOnly string Tool 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,
Tool.flyover is returned.
flyover Accessor ReadOnly string Tool Get the localized flyover string from this Tool's class
flyover Accessor StaticReadOnly string Tool 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,
Tool.keyin is returned.
frustumValid boolean ViewManip  
handleMask ConstructorProperty number ViewManip  
hidden Static boolean Tool If true, this Tool will not appear in the list from ToolRegistry.getToolList.
iconSpec Accessor ReadOnly string Tool Get the iconSpec from this Tool's class.
inDynamicUpdate boolean ViewTool  
inHandleModify boolean ViewManip  
isDragging boolean ViewManip  
isDraggingRequired ConstructorProperty boolean ViewManip  
isDynamicsStarted Accessor ReadOnly boolean InteractiveTool Call to find out if dynamics are currently active.
isZUp Accessor ReadOnly boolean ViewManip  
keyin Accessor ReadOnly string Tool Get the localized keyin string from this Tool's class
keyin Accessor StaticReadOnly string Tool 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 number | undefined Tool The maximum number of arguments allowed by Tool.parseAndRun, or undefined if there is no maximum.
If subclasses override Tool.parseAndRun, they should also override this method to indicate the maximum
number of arguments their implementation expects.
minArgs Accessor StaticReadOnly number Tool The minimum number of arguments allowed by Tool.parseAndRun. If subclasses override Tool.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 Tool The I18NNamespace that provides localized strings for this Tool.
nPts number ViewManip  
oneShot ConstructorProperty boolean ViewManip  
receivedDownEvent boolean InteractiveTool Used to avoid sending tools up events for which they did not receive the down event.
stoppedOverHandle boolean ViewManip  
targetCenterLocked boolean ViewManip  
targetCenterValid boolean ViewManip  
targetCenterWorld Point3d ViewManip  
toolId Accessor ReadOnly string Tool 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.
