The OpenEdge Hive

This object provides an alternate solution to using a treeview OCX, and demonstrate the power of ABL to achieve fast and sophisticated UI Objects. It supports all the basic treeview features, as well as drag and drop, node moves, popup menu's, plus it can load nodes in a very fast way (1000 nodes in 0.73 seconds on a 2GHz CPU, so faster than the MS OCX).

It works fine on Linux with Wine (much easier than with OCX's) so it helps to open the door to this configuration. The package includes sample code and documentation.
