Forms in MultiPageEditorPart
here's what I'm trying to do: I have a MultiPageEditorPart and want to create some pages (tabs). This works fine, I have my 2 pages. In the second page, I'm trying to add the following content: two sashforms, the left one should contain a tree, the right one some input fields (something like a form with some buttons, labels etc.)
Well, I simply do not understand how to do this in JFace/SWT. I tried reading several examples, but didn't manage to create my content as I want. I only need some hint, for eg. "you need to add to the multipageeditorpart x and call y, create a class that extends z ..."
Any help is appreciated.
ps: jface is very frustrating for java se developers.
