Methods

OverridedoActivate

  • doActivate(): void

  • Start reshaping, if findToolHandleAt finds a reshape handle at the mouse down point.

    If successful this sets handle to be the reshape handle that it finds and adornedLink to be the Link being routed. It also remembers the original link route (a list of Points) in case this tool is cancelled. And it starts a transaction.

    Returns void

OverridedoDeactivate

  • doDeactivate(): void

  • This stops the current reshaping operation and updates any link handles.

    Returns void

isApprox

  • isApprox(x: number, y: number): boolean

  • Compare two numbers to ensure they are almost equal. Used in this class for comparing coordinates of Points.

    Parameters

    • x: number
    • y: number

    Returns boolean

makeSegmentDragHandle

  • makeSegmentDragHandle(link: Link, adornment: Adornment, index: number): void

  • Create the segment dragging handles. There are two parts: one invisible handle that spans the segment, and a visible handle at the middle of the segment. These are inserted at the front of the adornment such that the normal handles have priority.

    Parameters

    Returns void

Overridereshape

  • reshape(newpt: Point): void

  • Change the route of the adornedLink by moving the segment corresponding to the current handle to be at the given go.Point.

    Parameters

    Returns void
