jface treeviewer with 2 columns [message #1015916]

Hi,

is there a way to create a treeviewer with two columns? I know it is Yes but i mean here where both columns have same structure. Assume you have an object 'car' with some properties that change over time. you have this data as versions and want to fill a tree with it so that every column (along with its children) represents one time stamp. The intention here is to make kind of line-to-line comparison.
I couldn't adapt the classes implementing Contentprovider and StyledCellLabelProvider to get this done.

Thanks alot,
Mok

I don't understand the request. Have you added TreeViewerColumn's?

Yes I added treeviewercolumns. Ok, consider this tutorial please
http://javawiki.sowas.com/doku.php?id=swt-jface:treetableviewer
The intetion in this demo is to have 3 columns (Land/Stadt, Person and Sex). Now I want to pass data of two (Städte in this case along with its persons,..etc) and display it in 6 columns (3 for first Stadt and 3 for second). Look at the picture plz.

I couldn't adapt the methods

getElements(Object cities)

getChildren(Object parentElement)

to get this done.
