    Question Creating circle-shaped JButtons?

    Hi all,

    JButtons by default creates rectangular buttons. I'd like to change the shape to a circle. The following is my code:
    public void createButtons(JPanel bottomPanel) {
     
    			JButton[] buttons = new JButton[16];
    			String[] alphabets = { "A", "B", "C", "D", "E", "F", "G", "H", "I", "J",
    					"K", "L", "M", "N", "O", "P"}; 
     
    			for (int i = 0; i < buttons.length; i++) {
    				buttons[i] = new JButton(alphabets[i]);
    				buttons[i].setSize(40, 40);
    				buttons[i].setActionCommand(alphabets[i]);
    				buttons[i].addActionListener(this);
     
    				bottomPanel.add(buttons[i]);
    			}
     
     
    		}

    The point is i want the shape of the buttons to be circular and not the default rectangular shape. Any ideas?

    Default Re: Creating circle-shaped JButtons?

    Use an appropriate LayoutManager, and set the size of the JButton using setPreferredSize (and setMaximumSize/setMinimumSize) to constrain its dimensions. If you have issues, I recommend posting an SSCCE so others can reproduce the problem and provide options to fix.
