in our reference section. Examples might include:
Creating connections in GEF
Using the Platform (SWT) Drag and Drop support w/GEF
How to extend keyboard support in GEF
Using "Direct Edit" in GEF
Creating complex figures in draw2d

Please describe what you consider to be a complex figure. I was thinking of
things like a UML class (with title, attributes, and operations), or a Node,
consisting of an Image, Text, and multiple decorations on the Image. The
"take home message" would be that you should avoid overriding validate() or
setBounds() on your figure, and maybe how to avoid coupling between the
figure and editpart/model.

Here are two suggestions:
1) How to properly subclass Figure.
2) Subclassing Figure for use in GEF diagrams.
But before you do that, completed Javadoc would also be greatly
appreciated. For example, from ImageCache:
>>>
checkout
public static Image checkout(Dimension d,
Object o)
Returns an image that is at least as big as the desired size. NOTE: (1)
The client should not dispose the image that is checked out (2) However,
the client should check the image back in when done (3) The given
dimension will not be modified by this method (4) The client should not
use the returned image's bounds for anything (since the returned image
could be bigger than requested) (5) If the size of the image is too big,
and the image cannot be created, this method will return null
Parameters:
d - The desired size of the image to be checked out
<<<
This is a pretty nice entry, however, what is the Object o parameter
used for? This Javadoc entry is frustrating for two reasons: (1) @param
o isn't documented at all (2) @param o's name is not meaningful.
Thanks in advance,
Dave

Thanks for the suggestions.

I understand your frustration. We are working on this whenever we can.
> appreciated. For example, from ImageCache:
org.eclipse.draw2d.util package is not exported by the plugin. We should
rename this package to internal.

That articles are OK ! But I think it would be interesting for the beginners
in GEF like me to write a small tutotial about building a graphical editor
with GEF step by step. It isn't necessary the example editor be complex. If
this tutorial exists now, please tell me where it is.
Thank you !
