Hello,

i am quite new to eclipse, but even more to gef.

i googled and found some examples for creating a "diagram schema editor"
etc.

but these examples are too overloaded to start with (at least for me)

now i am looking for a simple editor that only displays squares with
labels and some connections between them.

best regards,

Ben

When you downloaded the gef plugins you probably also downloaded an
examples plugin that includes src. Look for a plug-in named:
org.eclipse.gef.examples.source - it contains 4 examples my two
favorites are Shapes and Logic diagram. Shapes is simple enough to
digest with a days worth of playing. Logic is drawing kit for Circuit
logic will take a few more days to digest.

Hope that helps

Hi Ben,

If you search the archives or Google HelloGef1 you will find the HelloGEF
example series that does just that, a simple GEF editor with squares.

I am looking at getting these examples up to date for GEF 3.3 over the
summer, as they have not been updated since GEF 2.1.3.

Cheers...
Anthony

so as i see, there is no possibility to get it run under eclipse 3.2?

i imported hellogef1 into a project, and i get some errors, which i cannot
resolve.

but they are actually in there ... *shrug*

Hi Ben,

Yesterday I tried to run examples from the IBM Redbook about using EMF
with GEF and I had the same problem.
What I did was to go to the properties of the project -> Java Build Path
-> Libraries tab -> Add Library... button (on the right) -> choose
Plug-in Dependencies from the list -> click Next -> click Finish -> go
to the Projects tab -> remove all projects from the list -> click OK
This should make these problems disappear, but I suppose other will
appear ;)

Hope this helps,

Hi Again,

I have posted a new example to
http://www.eclipse.org/gef/reference/digraph1.php .

This first directed graph example is as simple as it gets.

Cheers...
Anthony
