Hide/Show a TreeColumn in a Tree [message #332806]

Hi All,

I have a TreeViewer with a few TreeColumns assigned.
Can anyone point me in the direction of finding out how to implement the
ability to toggle between hiding one particular
TreeColumn and making it visible again?

I want the user to be able to view/hide the last TreeColumn in the Tree.

Any ideas please?

Thanks in advance!!

I think you can just can set the column's width to 0 to hide it.
The JFace snippets page
(http://wiki.eclipse.org/index.php/JFaceSnippets) has an example of
showing/hiding columns with a nifty animation effect (Snippet 017).

Hope this helps,
Eric

Thanks, yeah I was looking briefly at that snippet but I guessed that just
setting it's width to zero would
have a [what would seem] weird affect on tabbing etc.

But I will give it a try anyway!

Thanks again.

Since 3.4 (3.4.1) we handle this correctly.

If it doesn't work it is bug but I'm 99.9% sure it works.
