Problems using Editingsupport combined with Drag and Drop [message #662386] Wed, 30 March 2011 09:37 Go to next message

Hi,

I am using a TableViewer with Editingsupport on some columns.
When I use DND it works fine except when I start the DND on one
of my columns with Editingsupport.
As soon, as I begin to move the mouse, the Editingsupport is started
and the DND seems to work (visually and without throwing exceptions),
but in the end the DND does not switch the selected object.

Can it be, the running Editingsupport somehow derails the DND?
What can I do to make this work?

Thanks in advance,
Dominik.

Found my problem.
The setValue-method of the Editing-Support used some
data, which the DND-Support already had moved. Embarrassed

Hello,

Can you detail a bit more how you fixed this problem, please? I'm facing it also but I don't understand how I can fix that with the setValue method.

From what I understood, the method isEditorActivationEvent() of the ColumnViewerEditorActivationStrategy is called although the button has not been released. This seems a bug to me. I wanted to return false for this method when a drag is detected or the button not released but the event we get as the parameter of this method does not contain enough information Sad

Regards,
