jFace Viewer not allowing deselect using ctrl click [message #557022]

Greetings:

I have a jFace TreeViewer that I have given a style bit of SWT.SINGLE. It will not allow a tree element to be deslected using ctrl click on the selected element.

I did find that deselect works if the style bit is set to SWT.MULTI

In my case I need SINGLE select only, with the ability to deselect an element, putting the tree in a no selection state.

I am using eclipse plugin development with eclipse 3.6

Any thoughts??

Thanks for your time.

Hi,

I think this is the default behavior of the platform.
However, you can override this default behavior and make the deselection work for SINGLE tree.
Here is an old thread on how to make deselection work by clicking outside the TreeItems --> http://dev.eclipse.org/newslists/news.eclipse.platform.swt/m sg45356.html
