I am creating a new Java Project the creating a new interface class and then chosing open with window builder. However I continue to receive "this is not a GUI class" error.
Can anyone assits, or point in the direction of a more in depth guide to use?
creating a new interface class and then chosing open with window builder.
Disclaimer: I prefer to hand code and haven't used the window builder.
I doubt if you will be able to edit an interface with the window builder. Try creating a Composite or subclass a Widget and then editing with the window builder
