Hi,

Is it possible to hide and show columns with swt?
Or would I better use swing?

Thx in advance

We have set the width of the column to 0, that worked fine.
To set it invisible is not possible in SWT, as far as I know.

thx for that tip Peter!

But I'm having @ the moment probs with setInput ( .. ) :(
I'm going to try to explain my situation...

tv.setInput(lijst);
tv = TableViewer
list = ArrayList with Person-objects (1 row in table = 1 Person)

but he gives an error on that setInput line ... :S
java.lang.ClassCastException

What kind of 'thing' is the argument of setInput ? 'an object' ... :S

Thx in advance !!!!!

The Input is the - usually list of - domain objects that should be
displayed. You have to be sure that the ContentProvider and
LabelProvider are able to handle these objects.
You could have a look at the article "How to use the JFace Tree Viewer"
at http://eclipse.org/articles/index.html.
It is similar with a TableViewer.
I'm not so firm with the viewer stuff, so I'm sorry I'm no real help there.
