Dragging TreeItem with markup [message #1851629]

In our RAP application, we've got a SWT Tree - without JFace viewer.
The Tree is RWT.MARKUP_ENABLED, each item is filled with a HTML span.

The problem is that we need to enable drag and drop inside the tree, and drag translucent content seems to be based on first column text and image.
HTML markup content appears under cursor while dragging, which is troublesome.

index.php/fa/41912/0/

Obviously the issue is resolved without using markup on first column, but we wouldn't want to do that.

I also tried to embed markup inside a Label, and Label inside TreeItem with cell editor, but result is not very satisfying (Label area is not draggable).

Is there a way to adjust a user-friendly content under cursor, or hide the content ?

Is it a known limitation ?

Or should we use Templates instead ?

Regards,

Julien.

Hi,

I've just tested the DND on Tree with markup in our Examples demo and it's working as expected (see attached patch).
Please provide a self running snippet to demonstrate the problem.

Best regards,
Ivan

.... now I see... The problem is about showing the HTML markup while dragging, but the drag-and-drop itself is working fine. Isn't it?
Please open an enhancement request about this issue.

That's it.

Thank you for your answer.

Have you got a snippet of tree or table with Template, maybe it suits better on dragging ? Seems appropriate in our case...https://www.eclipse.org/rap/developers-guide/devguide.php?topic=tree-table.html&version=3.14#templates
