Methods

Name Description
constructor(..._args: any[]): PrimitiveTool    
autoLockTarget(): void Called on data button down event to lock the tool to its current target model.  
exitTool(): void    
getPrompt(): string Returns the prompt based on the tool's current state.  
isCompatibleViewport(vp: Viewport | undefined, isSelectedViewChange: boolean): boolean Determine whether the supplied Viewport is compatible with this tool.  
isValidLocation(ev: BeButtonEvent, isButtonEvent: boolean): boolean Checks that the adjusted point from the supplied button event is within the project extents for spatial views.  
onRedoPreviousStep(): Promise<boolean> Called to reinstate to a previous tool state (ex.  
onReinitialize(): void Called to reset tool to initial state.  
onRestartTool(): void Abstract Called when an external event may invalidate the current tool's state.  
onSelectedViewportChanged(_previous: Viewport | undefined, current: Viewport | undefined): void Called when active view changes.  
onUndoPreviousStep(): Promise<boolean> Called to reverse to a previous tool state (ex.  
requireWriteableTarget(): boolean Called from isCompatibleViewport to check for a read only iModel, which is not a valid target for tools that create or modify elements.  
run(): boolean Establish this tool as the active PrimitiveTool.  
saveChanges(): Promise<void> Tools need to call SaveChanges to commit any elements they have added/changes they have made.

Inherited properties

Name Type Inherited from Description
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 the
.json file for the current locale of its registered Namespace (e.g. "en/MyApp.json"). If that key is not in the localization namespace,
the flyover property 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 the
.json file for the current locale of its registered Namespace (e.g. "en/MyApp.json"). If that key is not in the localization namespace,
the keyin property is returned.
hidden Static boolean Tool If true, this Tool will not appear in the list from ToolRegistry.getToolList.
isDynamicsStarted Accessor ReadOnly boolean InteractiveTool Call to find out if dynamics are currently active.
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 the
.json file for the current locale of its registered Namespace (e.g. "en/MyApp.json")
namespace Static I18NNamespace Tool 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 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.
toolId Static string Tool The unique string that identifies this tool.
