Changes between GEF version 0.5.1 and GEF v05.
Date: 98/02/02

Overall the changes are fairly minor.  However, the copyright change
demands a new release and I wanted to take this opportunity to fix a
few bugs pointed out by GEF users.  If you have made substantial
changes to the GEF source code you will probably want to selectively
apply the same changes to your own copy.

1. Changed the version numbering scheme to use 0.n and 0.n.m instead
of 0n.  This did not change any code, just my web site.

2. Changed the GEF copyright statement in all files to indicate that
commercial users of GEF must contact Prof. David Redmiles.  This is
now required because GEF is being developed as a small part of a
government research grant, and we must report to the funding agency on
the industrial impact of our research products.

3. Fixed the GEF Makefiles to elimiate any trailing backslashes that
cause problems with some make utilities.

Many of the following changes were contributed by GEF users Nathan
Sharp and Walter Rott.

4. Added an addAttr method to ActionSetAttr.java.

5. Changed Editor.view(LayerComposite) to call damageAll() instead of
calling paint(Graphics) directly.

6. Added a stop() method to Editor that stops all threads associated
with the Editor. Also added stop() to RedrawManager.

7. Changed Editor.java to give its _eventHandler thread a String name.

8. Changed FigText.java so that the backspace key will delete a
character and the delete key will delete the FigText.  Previously it
was impossible to delete a FigText via the keyboard.

9. Changed FigPoly to use backspace to remove a vertex and leave the
delete keystroke to mean deleting the entire Fig.

10. Changed ModeExampleKeys to use delete to delete a selected
DiagramElement and ignore backspace.  Now delete deletes anything and
backspace is handled by the selected diagram element.

11. Changed Globals.java to not show _tabPropFrame as part of its
static initialization.  This was an unpopular feature of GEF that I
had initially put in to work around an intermittent failure in
Component.createImage(). This change may cause early calls to
createImage() to return null under some JVMs.  If you think
createImage() is returning null, you can uncomment this line or call
Globals.startPropertySheet from your own code.

12. Changed NetList.java: Added a check to make sure that NetNodes and
NetArcs added to a NetList are only added once.

13. Changed SelectionMultiple so that keystrokes will only be passed
to Figs when there is a single Fig selected.  Previously it was
impossible to nudge or delete multiple Figs if one or more of them was
a FigText.

14. Changed RedrawManager to set the default redraw frame-rate to 40
frames a second (up from 20).  This is because more people are using
faster JITs now.  The frame-rate setting is only a suggestion, if your
particular JVM on your machine cannot keep up, redraws will still
work.

15. Removed Preloader, Progress, and all associated Package classes.
The preloader was most useful when web browsers slowly downloaded all
.class files individually.  Now Netscape Navigator and MS IE both seem
to handle .zip and .jar files.  Plenty fo Progress widgets are
available from many sources, but if anyone wants mine I will gladly
provide it separately.

16. Commented out preloading and JVM specific configuration code in
demo/FlexibleApplet.java and demo/EquipmentApplet.java.

17. Commented out all calls to DebugLog.  DebugLog is basically a way
for me to control which println's are exectued by using a command line
flag that sets a system property.  However, accessing system
properties is not always allowed for applets.

18. Removed the package uci.graphedit.contrib.  No one seems to be
using it.

19. Added a new demo, ScrollingApplet.  This demo shows an easy way to
implement a large drawing area.  This demo will only compile under JDK
1.1 because it uses the AWT ScrollPane class.  Better scrolling
support is one goal for the next release.
