I am working on an application in which I would like to use the "rubberbanding" feature of 2D GMR, but I am stuck on a point, and perhaps someone else has the answer. The application creates nodes and arcs connecting the nodes. For nodes, a segment containing the text identifying the segment is created. For the arcs, a segment containing the polyline and the text labeling it is created. When the arc is created, the endpoints are adjusted by the application to "snap" to the nodes connected by the arc. That is the extent of the linkage between the segments: they appear associated due to their physical proximity. The challenge is to be able to move a node *AND* the end point of the arc(s) "connected" to the node using the GM_$MODELCMD_SET_MODE routine to set up rubberbanding. As best I can tell, rubberbanding is supported within a segment, but not across multiple segments. Is there any hope of using any GMR calls to directly accomplish this behavior? (I am using the bundled version, not 2.n). -- ___________________ Darryl C. Conliffe conliffe@caen.engin.umich.edu (313) 721-6069 -------------------
