I am trying to get a JPanel to display a series of Buttons.On each of these buttons is one of the values associated to my Sudoku Board Values. I have created my board added a menu and now i am trying to display the selectable options below the menu but before the board..in the same Jframe. I was hoping i could put all my buttons onto the JPanel and put that panel onto the Frame. It will display the JPanel but none of the buttons. At one time i got the panels to display but none of them were sized and there were to many. The question i have to be more specific is the code i am using correct for displaying my series of buttons on my JPanel, that is placed on in a Frame containing my Sudoku Board, which is also a series of buttons.
Is this final toolbar and buttons to much for this single JFrame, is that why it is not working? Anyways here is just the code for my toolbar which is my JPanel.
class ToolBar extends JPanel {
// instance initializer (constructor equivalent)
public ToolBar() {
super();
this.setLayout(myLayout);
myLayout.setAlignment(FlowLayout.TRAILING);
Button[] panelButton = new Button[size];
//Rectangle rec = new Rectangle(330,45,BUTTON, BUTTON);
//setBounds(rec);
setPreferredSize(new Dimension(330, 45));
for(int i = 0; i < size; i++) {
Rectangle r = new Rectangle(12, 12, 22, 22);
center = new ImageIcon(view.drawSymbol(i));
panelButton[i]= new Button();
panelButton[i].setIcon(center);
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);
}
}
};
I used setBounds 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:
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);
}
}
};
I am also posting the whole testing code below:

Look for the line this.add(new ToolBar()); where I instantiate and add your toolbar to my JFrame.
A piece of advice:
Avoid AWT components as much as possible
