26 -
27 -=== Operations: ===
28 -
29 - - remove selected nodes from a connectivity, results in a new connectivity containing only the nodes that were not selected;
30 -
31 - - remove unselected nodes from a connectivity, results in a new connectivity containing only the selected nodes;
32 -
33 - - remove unselected edges, results in a new connectivity with the same number of regions but without the edges of unselected regions;
34 -
35 - - remove selected edges,  results in a new connectivity with the same number of regions but without the edges of selected regions.

37 -
38 -=== Usage: ===
39 -
40 -After instantiating the widget it allows export of the currently selected connectivity:

55 -
56 -display(wid)
57 -# ....do some operations...
58 -# replace None in the method below with the gid of the connectivity you wish to export
59 -# if no gid is provided it will export the connectivity currently viewed
60 -
