How to draw line between two TreeView in GEF [message #153476] Sun, 10 October 2004 12:34 Go to next message

Hi all,
I want to draw lines between two TreeView, like the attached image
does.The lines have their own properties, so I use GEF to implement it. My
plan is to do like this:
----------------------
| | | |
| | | |
| Tree | GEF | Tree |
| | | |
| | | |
----------------------
but I don't know if we could connect two TreeItem. How could I implement
it?
And there is org.eclipse.gef.ui.parts.TreeViewer in GEF. I wonder what
that for,can I use that to build a tree?

I don't think you can:

1) Paint on top of an SWT tree reliably.
2) Obtain the bounding box of a TreeItem.

You may be able to calculate the Y-location of a treeitem, and paint
everything completely outside the tree. You will still have to track
expand/collapse of the treeitem, and scrolling of the tree. This may not be
possible either.

The alternative is to render your own thing which looks like a tree, using
GEF and Figures perhaps.

Thanks for advice. It seems the only way is to build the TreeView in GEF,
then how to use org.eclipse.gef.ui.parts.TreeViewer to build a TreeView?
Is there any example or code snippet shows how to that?

Thanks.

Best regards,
lee

TreeViewer is for native SWT Tree control. That won't help you with your
problem.

In the WSDL editor from IBM wtp package (which is contributed to the web
tools project ), there is exactly what you want.

Hey Gunay,
I am not sure if this thread is dead or not.

I am in kind of similar situation and not found any relevant link where I can render the GEF draw2d tree.
In your previous reply if you are talking about WSDL editor. http://www.eclipse.org/webtools/community/tutorials/WSDLEditor/images/wsdleditor-new-skeleton.jpg

Can you help me to point the source even I have seen the source code of all versions of WTP plugins.

Thanks and Regards,
Sanjeev

Hi Gunay,

I am also similar kind of situation and in fact I come across the new WSDL editor screenshot. Please find the screenshot attached.

I am exactly looking the same thing.

But, I could not find the source of this editor, even I am not sure with which version of WTP it is integrated. I saw the Juno version of eclipse as well but could not find how to open this.

If any one can help me to find the source code of new WSDL editor.

Thanks and Reagrds,
Sanjeev
