[Zest] Recursively nested Elements [message #827531]

Hi all,

first of all I was really astonished how easy graphs can be described
with Zest.
I have one Question. Is there a way to nest Graphelements recursively?
I was able to get elements drawn into a container by making my
ContentProvider implement INestedContentProvider. However I wasn't able
to nest elements deeper that one level because the Framework doesn't
consider the ContentProvider, when children of a container are created.
What am I doing wrong?

Thanks in advance

Veit

As of now, nested content providers does not support recursively nested graph elements.

When using the SWT API, you could add new nodes inside other nodes, as shown in the nested graph snippet: http://git.eclipse.org/c/gef/org.eclipse.zest.git/tree/org.eclipse.zest.examples/src/org/eclipse/zest/examples/swt/NestedGraphSnippet.java

Hi Zoltan,

thanks for the quick response.
I will try another way to to express my structure then.

Cheers

p.s. Thanks for pointing me to the snippet anyhow. I wasn't aware of
CompositeLayouts too ;)

Be careful with the snippet. I opened the Zest 2.0 version; if you are using 1.x, some adaptation might be required.
