Hello, I wish to remove this side option button from my Jinternalframe: print da tela

After reading in some places, I saw that theoretically this employee command to remove the button: 

((BasicInternalFrameUI)this.getUI()).setNorthPane(null);

When I try to use this, I get the following error: 

Main.java:165: error: cannot find symbol
        ((BasicInternalFrameUI)this.getUI()).setNorthPane(null);
          ^
  symbol:   class BasicInternalFrameUI
  location: class Window
1 erro

Follow, my code word: 


class Window extends JInternalFrame{
    Window(String name,  int id){
        [...]
        ((BasicInternalFrameUI)this.getUI()).setNorthPane(null);

        [...]
    }
    public void setPosition() {
        [...]
        }
    }

class Main{
    public static void main(String args[]) {
        [...]
    }
}

  • In order for us to see the problem more broadly, it is essential to test, however, your code, as it is only a fragment, does not allow this. If possible, provide a reduced version of your code, that it is possible to run only the problem so that we can help you ;)

Try to put this in the class builder.

setBorder(javax.swing.BorderFactory.createEmptyBorder(0, 0, 0, 0));
BasicInternalFrameUI bi = (BasicInternalFrameUI)this.getUI();
bi.setNorthPane(null);

This removes the options menu, but also the edge. You can make a button close and minimize customized too, if you want to keep, but there goes the taste.
