Java SWT TreeViewer with one column that needs to

Question

I have a TreeViewer used in an eclipse plugin that uses a content provider and a label provider that implements all of (ITableLabelProvider, IFontProvider, IColorProvider).

But I need one of the columns of the table it creates to hold "links" - underlined blue text that when clicked causes some popup to open. I guess what I want to do is cause that single column to hold styled text and not just text, and attach a listener to the items in that column of the tree, but I couldn't figure out how to do it.

Answer 1

Use a separate label provider for each column using TreeViewerColumn:

TreeViewer viewer = new TreeViewer(.....);

TreeViewerColumn col1 = new TreeViewerColumn(viewer, SWT.LEAD);

col1.setLabelProvider(col1 label provider);

... repeat for other columns

For columns that require styling use DelegatingStyledCellLabelProvider as the column label provider as described here

Note: Do not call viewer.setLabelProvider when using column label providers.
