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.
Constructs a GeometryReshapingTool and sets the handle and name of the tool.
Optional init: Partial<GeometryReshapingTool>ReadonlyadornedGets the go.Shape that is being reshaped. This must be contained within the selected Part.
This read-only property returns the go.GraphObject that is the tool handle being dragged by the user. This will be contained by an go.Adornment whose category is 'GeometryReshaping'. Its go.Adornment.adornedObject is the same as the adornedShape.
A small GraphObject used as a reshape handle for each segment. The default GraphObject is a small blue diamond.
Gets or sets whether this tool supports the user's addition or removal of segments in the geometry. The default value is false. When the value is true, copies of the midHandleArchetype will appear in the middle of each segment. At the current time, resegmenting is limited to straight segments, not curved ones.
A small GraphObject used as a reshape handle at the middle of each segment for inserting a new segment. The default GraphObject is a small blue circle.
ReadonlyoriginalThis read-only property remembers the original value for go.Shape.geometry, so that it can be restored if this tool is cancelled.
The maximum distance at which a resegmenting handle being positioned on a straight line between the adjacent points will cause one of the segments to be removed from the geometry. The default value is 3.
The name of the GraphObject to be reshaped. The default name is 'SHAPE'.
OverridecanOverridedoStart 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 adornedShape to be the go.Shape being reshaped. It also remembers the original geometry in case this tool is cancelled. And it starts a transaction.
OverridedoOverridedoOverridedoCall reshape with a new point determined by the mouse to change the geometry of the adornedShape.
OverridedoReshape the Shape's geometry with a point based on the most recent mouse point by calling reshape, and then stop this tool.
Change the geometry of the adornedShape by moving the point corresponding to the current handle to be at the given go.Point. This is called by doMouseMove and doMouseUp with the result of calling computeReshape to constrain the input point.
the value of the call to computeReshape.
OverrideupdateShow an go.Adornment with a reshape handle at each point of the geometry. Don't show anything if reshapeObjectName doesn't return a go.Shape that has a go.Shape.geometry of type go.GeometryType.Path.
The GeometryReshapingTool class allows for a Shape's Geometry to be modified by the user via the dragging of tool handles. This does not handle Links, whose routes should be reshaped by the LinkReshapingTool. The reshapeObjectName needs to identify the named go.Shape within the selected go.Part. If the shape cannot be found or if its go.Shape.geometry is not of type go.GeometryType.Path, this will not show any GeometryReshaping go.Adornment. At the current time this tool does not support adding or removing go.PathSegments to the Geometry.
