How to make WindowBuilder create fields that are n

问题:

I am using WindowBuilder for Eclipse Java.

When I make a Button or a Menu (or anything), it creates the fields nested inside of the constructor. Is there any way to make them fields and then initialized in the constructor so I can use them outside of the constructor? Thank you.

ie: FROM

public GUIFrame() {
    JMenuBar menuBar = new JMenuBar();
}

TO

public JMenuBar menubar; 
public GUIFrame() {
    menuBar = new JMenuBar();
}

There's a button to convert an element from "local to field".

If you want all components to be fields by default: Windows -> Preferences -> WindowBuilder -> Swing -> Code Generation -> Find "Variable generation" and select the "Field" tab.
