It simply creates a JFrame window. How to make it so that there is no standard "maximize" button?

  • Standard frame.setResizable(false); will not work? Or just need to hide? - Alexey Shimansky
  • it is necessary to hide it, i.e. so that this button is not visible at all - oleg
  • If you have been given the correct answer - vote for it \ check it correct (gray tick on the side of the answer). This will help others understand that the answer came up to solve the problem. - Alexey Shimansky

Something no special information. There is an option only to kill the default scenery setUndecorated(true); and then add your custom panel, buttons again and hang up handlers on these buttons.

Here is the code, I tried to explain with comments, as far as I could. It seems everything is clear.

 import javax.swing.*; import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; /** * Created by iprogrammer on 13.06.2016. */ public class Main extends JFrame { JPanel p; JMenuBar mb; JButton close, min; int pX,pY; public Main() { createAndShowGUI(); } private void createAndShowGUI() { // Custom look and feel try { UIManager.setLookAndFeel("javax.swing.plaf.nimbus.NimbusLookAndFeel"); }catch(Exception e){ } setDefaultCloseOperation(EXIT_ON_CLOSE); // Π£Π±ΠΈΠ²Π°Π΅ΠΌ Π΄Π΅Ρ„ΠΎΠ»Ρ‚Π½ΡƒΡŽ Π΄Π΅ΠΊΠΎΡ€Π°Ρ†ΠΈΡŽ (Ρ‚.Π΅.

It turns out something like this:

The rest, I think, you can finish yourself.
