Class RotateMultipleTool

GoJS® Diagramming Components
version 3.0.1
by Northwoods Software®

This is an extension and not part of the main GoJS library. Note that the API for this class may change at any time. If you intend to use an extension in production, you should copy the code to your own source directory. See the Extensions intro page for more information.

Hierarchy

The RotateMultipleTool class lets the user rotate multiple objects at a time. When more than one part is selected, rotates all parts, revolving them about their collective center. If the control key is held down during rotation, rotates all parts individually.

Caution: this only works for Groups that do not have a Placeholder.

If you want to experiment with this extension, try the Rotate Multiple sample.

Methods

OverridecomputeRotate

  • computeRotate(newPoint: Point): number

  • Calculate the desired angle with different rotation points, depending on whether we are rotating the whole selection as one, or Parts individually.

    Parameters

    • newPoint: Point

      in document coordinates

    Returns number

OverridedoActivate

  • doActivate(): void

  • Calls go.RotatingTool.doActivate, and then remembers the center point of the collection, and the initial distances and angles of selected parts to the center.

    Returns void

OverridedoDeactivate

  • doDeactivate(): void

  • Clean up any references to Parts.

    Returns void

Overriderotate

  • rotate(newangle: number): void

  • Rotate all selected objects about their collective center. When the control key is held down while rotating, all selected objects are rotated individually.

    Parameters

    • newangle: number

    Returns void
