Is it possible to define a Customizer similar to those in Jigloo GUI Builder?
So when I double click a component, a custom editor pops up.

Yes, WindowBuilder supports java.beans.Customizer for Swing components.

Thanks, I found out you have to open it with right click -> customize.
However, the changes I make to the bean with my customizer do not work.
The customizer looks like this:

===========================================
public class CustomTextfieldCustomizer extends JPanel implements Customizer {

private CustomTextfield beanField;

public CustomTextfieldCustomizer() {
this.initGUI();
}

...

@Override
public void setObject(Object bean) {
this.beanField = (CustomTextfield) bean;
this.updateValues(this.beanField);
this.initActions();
}

...

public void applyChanges(CustomTextfield bean) {
this.firePropertyChange("name", bean.getName(), this.getTxtName().getText());
this.firePropertyChange("description", bean.getDescription(), this.getTxtDescription().getText());
this.firePropertyChange("text", bean.getText(), this.getTxtInitialValue().getText());
}
}
===========================================

After Pressing the ok button inside the customizer, applyChanges() is called.
This works fine with jigloo but nothing happens in Window Builder.

Works for me.
Please post full sources of Bean, BeanInfo and Customizer.

Seems like I misunderstood the way, window builder handles customizers.
I've added my own ok and cancel buttons and now there are 2 of each when opening the customizer in window builder. How can I add an action listener to the window builder ok/cancel buttons?

OK/Cancel buttons are buttons of enclosing JFace dialog, you can not access them from Swing customizer.
Do you have any official documentation or tutorial which shows that Customizer should use its own OK/Cancel buttons?
I don't see anything like this here.

Me neither. I did it this way because I wanted to define the behaviour for the ok and the cancel button myself.

I've tried it like that now:
Whenever the user changes a value inside the customizer, the coresponding bean setter(not firePropertyChange because it did nothing) will be called.
This works fine when pressing the ok button but the cancel button causes odd behavior.
After Pressing Cancel, the SourceCode and the Design View representation of the bean do not change. This is ok.
But when I open the customizer the next time, it is filled with the changes made before pressing cancel.

How can I revert all the changes made to the bean after pressing cancel? Or only apply changes to the bean after pressing ok?
Do you have an example of how its done right?
