When I click on the design tab I get this error:
Incompatible Java Versions Eclipse is running under 1.7, but this Java project has a 1.8 Java compliance level, so WindowBuilder will not be able to load classes from this project. Use a lower level of Java for the project, or run Eclipse using a newer Java version.
I've checked in window>preferences that:
- >java>compiler is set to 1.8
- >java>installed JREs has a 1.8 JDK as the default
Have I missed something?
