Empty Design tab on Mac M1 Pro

[nelo1986]

Hello,

I'm trying to use Eclipse and Window Builder to make an SWT project, but and have the following issue.

The file compiles and executes well:

I have tried lots of different versions of JDK, Eclipse and WB. Currently, I have the following versions.

Window Builder

Eclipse version: Version: 2022-12 M1 (4.26.0 M1)

Java: JDK 18

There aren't errors or warnings, only the issue explained above.

Could you help me?

I have uninstalled the Eclipse and Dark Theme. Nothing changed.
In order to give more information, when I create a Swing -->Application Window , the Design tab works fine but after Run As --> Java application It doesn't run.

Design tab on Swing Application Window

Design tab on SWT Application Window

So, I suspect that the problem could be on referenced Libraries which use SWT.

Information details of WindowBuilder installed

This does not look like a bug of WindowBuilder, but a misconfiguration of the Java Build Path of your project for SWT.

Follow the SWT documentation (in your case, for macOS on Apple silicon (M1), download and use swt-4.25-cocoa-macosx-aarch64.zip).
