If you are worried that not all of your content will fit on the screen on all resolutions, here are a couple of things to consider:
- Wrap your whole content in a
ScrolledComposite
(as you already mentioned). - Try splitting your content into several parts and either use a wizard type of GUI or tabs, depending on your requirements.
- Try avoiding setting a fixed size for the window. Either let it compute its optimal size or at least set the size to a percentage of the screen.
