72 | This sample demonstrates the PolylineLinkingTool, which replaces the standard LinkingTool. The tool is defined in its own
|
73 | file, as <a href="PolylineLinkingTool.ts">PolylineLinkingTool.ts</a>.
|
74 | </p>
|
75 | <p>
|
76 | The user starts drawing a new link from a node in the normal manner, by dragging from a port, which for feedback purposes
|
77 | has a "pointer" cursor. Normally the user would have to release the mouse near the target port/node. However with the
|
78 | PolylineLinkingTool the user may click at various points to cause the new link to be routed along those points. Clicking
|
79 | on the target port completes the new link. Press <b>Escape</b> to cancel, or <b>Z</b> to remove the last point.
|
80 | </p>
|
81 | <p>
|
82 | Furthermore, because <a>Link.resegmentable</a> is true, the user can easily add or remove segments from the route of
|
83 | a selected link. To insert a segment, the user can start dragging the small diamond resegmenting handle. To remove
|
84 | a segment, the user needs to move a regular reshaping handle to cause the adjacent two segments to be in a straight
|
85 | line.
|
86 | </p>
|
87 | <p>
|
88 | The PolylineLinkingTool also works with orthogonally routed links. To demonstrate this, uncomment the two lines that initialize
|
89 | <a>Link.routing</a> to be <a>Link.Orthogonal</a>.
