API Reference > imodeljs-frontend > Views > ViewManager > dropViewport dropViewport Method Remove a Viewport from the list of opened views, and optionally dispose of it. Typically a Viewport is dropped when it is no longer of any use to the application, in which case it should also be disposed of as it may hold significant GPU resources. However in some cases a Viewport may be temporarily dropped to suspend rendering; and subsequently re-added to resume rendering - for example, when the Viewport is temporarily hidden by other UI elements. In the latter case it is up to the caller to ensure the Viewport is properly disposed of when it is no longer needed. Attempting to invoke any function on a Viewport after it has been disposed is an error. dropViewport(vp: ScreenViewport, disposeOfViewport: boolean = true): BentleyStatus note raises onViewClose event with vp. Parameter Type Description vp ScreenViewport the Viewport to remove. disposeOfViewport boolean Whether or not to dispose of the Viewport. Defaults to true. Returns - BentleyStatus SUCCESS if vp was successfully removed, ERROR if it was not present. Defined in core/frontend/src/ViewManager.ts Line 291 Last Updated: 11 June, 2024
