Hello everyone.

Please, need some help with this.

Is there a way of adding a condition to my palette or my components, so that it´ll only display in a determined situation?

I need to show some components if I open a file and show others components if I open other kind of file.

Is it possible in WB ?

Thanks a lot.

Sure. That is how WindowBuilder shows Swing widgets when looking at a Swing UI and SWT widgets when looking at an SWT UI (and both files are .java files).

Hello.

I added this condition to my component:

condition="MyClass.myMethod()"


But, when I run it, I got an error:

[Error: could not access: MyClass; in class: null]
[Near : {... Unknown ....}]
