[Qt-jambi-interest] QTreeModel with several columns

[Tom Schindl]

Oh sorry. I'm using SVN-Externals a lot on Eclipse-Servers. So the
correct URLs are:

Code:
https://dev.eclipse.org/svnroot/eclipse/org.eclipse.ufacekit/bundles/incubation/org.eclipse.ufacekit.incubation/org.eclipse.ufacekit.ui.qt/org.eclipse.ufacekit.ui.qt.jface/

Examples:
https://dev.eclipse.org/svnroot/eclipse/org.eclipse.ufacekit/bundles/incubation/org.eclipse.ufacekit.incubation/org.eclipse.ufacekit.ui.qt/org.eclipse.ufacekit.ui.qt.jface.example/

The one below holds only the Eclipse-specific setups.
