Eclipse WindowBuilder 设计选项卡是空的？

Question

I'm new to the WindowBuilder tool of Eclipse (or any frontend dev), and I installed WindowBuilder, SWT to check it out. When creating a new project, I go to:

New > Others > WindowBuilder > SWT Designer > SWT/JFace Java Project

When creating a new class, I go to:

New > Others > WindowBuilder > Swing Designer > Application Window or JFrame , or Under > SWT Designer > SWT >Application Window .

This generates an initial Main code and I have Source and Design Tabs below. My problem is that when going to the design tab it's always empty as seen below:

The initial code in class has this:

And when executed creates this window:

I can't find any answers for this problem, and all tutorials I'm seeing have items inside the Design Tab where they can start exploring it.

I faced the same problem, and what i did was to update the windowbuilder to version: 1.9.2......

That solved the problem for me.

PS: Using Eclipse Photon

Answer 2

Uninstall eclipse completely, the only thing you need to leave is the eclipse-workspaces folder, so your projects will remain saved.

To uninstall it completely you need to:

1. Delete the "eclipse" folder in "C:\\Users\\YourName".
2. Delete the desktop shortcut.
3. Delete the ".p2" folder in "C:\\Users\\YourName".

Reinstall eclipse from the official site. This worked for me.
