Per installare WindowBuilder su Eclipse andiamo alla voce di menu Help -> Eclipse Marketplace…, digitiamo “windowbuilder” nel campo “Find:” e premiamo Invio Download The Appendix.
Premiamo quindi il bottone Install e seguiamo lo wizard finchè non ci viene chiesto di riavviare Eclipse Exo Growl download.
Finally, I fix this problem by checking this website: https://stackoverflow.com/questions/38058676/installing-windowbuilder-on-eclipse-neon
how to install windows builder?
I just tried with a brand new Eclipse RCP/RAP 2019-12 using the Marketplace as in the original post: installation ended successfully and also had no problem in editing an SWT View.
We always used it for editing SWT parts, never for Swing.
