In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv31257/src/net/sourceforge/bprocessor/gui
Modified Files:
GUI.java
Log Message:
Implemented a simple Undo/Redo mechanism that remembers the entire model state for each operation Ð this may be too slow with larger models (and require large amounts of memory).
The history is cleared when saving the model.
