copied!<p>I used <code>setBounds</code> on the toolbar to make it visible and also set the background to red just for testing it, replaced AWT buttons with Swing JButtons and I also set some text on the buttons. I commented out something on my testing code in order to compile and but put them back below:</p> <pre><code>class ToolBar extends JPanel { // instance initializer (constructor equivalent) public ToolBar() { super(); this.setLayout(myLayout); myLayout.setAlignment(FlowLayout.TRAILING); JButton[] panelButton = new JButton[5]; this.setBackground(Color.red); this.setBounds(0, 0, 200, 200); //Rectangle rec = new Rectangle(330,45,BUTTON, BUTTON); //setBounds(rec); setPreferredSize(new Dimension(330, 45)); for (int i = 0; i < 5; i++) { Rectangle r = new Rectangle(22, 22); panelButton[i] = new JButton(); panelButton[i].setText(" "); panelButton[i].setIcon(new ImageIcon(view.drawSymbol(i))); panelButton[i].setOpaque(true); panelButton[i].setBorder(BorderFactory.createLineBorder(Color.black)); panelButton[i].setBounds(r); this.add(panelButton[i]); this.setComponentOrientation(ComponentOrientation.LEFT_TO_RIGHT); this.setVisible(true); } } }; </code></pre> <p>I am also posting the whole testing code below:</p> <pre><code>import java.awt.Color; import java.awt.ComponentOrientation; import java.awt.Dimension; import java.awt.Rectangle; import javax.swing.BorderFactory; import javax.swing.JButton; import javax.swing.JPanel; /* * To change this template, choose Tools | Templates and open the template in * the editor. */ /** * * @author hahahaha */ public class NewJFrame extends javax.swing.JFrame { /** * Creates new form NewJFrame */ public NewJFrame() { initComponents(); this.add(new ToolBar()); } /** * This method is called from within the constructor to initialize the form. * WARNING: Do NOT modify this code.
