Move a widget in the tree with FormLayout

[domfe]

Hi.
My composite layout is of type FormLayout, the composite has three widgets.
I'm not able in the Tree Structure to move the elements and change the order, for example to
change the tab list (I'm in XWT) as I can do if the Composite has an absolute layout.
Is there a preference to allow this?

Thanks.

Thank Eric. I've just upgraded but I can't test it. The designer give me an error when using FormLayout in the container.

<Shell xmlns="http://www.eclipse.org/xwt/presentation" xmlns:x="http://www.eclipse.org/xwt" x:Class="test.Example2" text="XWT Application">

Thanks again.

[Eric Clayberg]

Please resubmit using the "Contact Support" button in the error window. We need to see the entire ".log" file.

Thank you.

[Eric Clayberg]

Thanks for the example, but it opened and edited just fine on our end.

Try the latest build and see if it makes any difference...

Hi Eric,
now I can move a widget up and down the tree.
I did the test with "FormLayout editing mode" on "Automatic placement".
The "Classic placement" gives me error so I open another post for
this specific problem.

Thank you a lot.

Give this a try using the latest build...
