Internal frame adjustable

Asked

I made a simple code in netbeans from an internalframe that loads inside the jframe, but the internalframe is a fixed size.

If I open it with a full screen setExtendedState(java.awt.Frame.MAXIMIZED_BOTH); He gets an empty space

If I try to decrease the screen size, it cuts a piece

A while ago I had made this same code and it automatically adjusted by screen size, someone knows how to do it back?

        initComponents();
        setExtendedState(java.awt.Frame.MAXIMIZED_BOTH); // iniciar com tela full
    }

  • What do you want to adjust after all? This code was generated by netbeans and it is difficult to change anything in it.

  • I wanted to know if you have any option to leave the code responsive, because this internalFrame is screwed inside jFrame: https://i.imgur.com/lykkMVk.png https://i.imgur.com/Yxyhv7w.png 2 points: Not getting the whole screen, and when I decrease the screen by cutting a part This one, however, it becomes fullscreen and if it decreases it resizes: https://i.imgur.com/vUPF0n.png https://i.imgur.com/wRYrkZf.png And the two I did it in a standard way.
