Hi, the question from Tom let me remember an other very old split-pane problem for me. In my platform-apps I have a TopComponent that I want to split into two parts.
For this I use the swing split-pane component. This works, but it looks different to the split planes between the editor and output-window I think there should be a specific netbeans platform splin-pane implementation. Where it is? Can I reuse it? best regards Oliver
