Revision as of 15:42, 23 November 2010
This tutorial gives a brief overview of what to do to get a small, graphical Minesweeper game running on your Overo. If you have not done so, please go through the tutorials Eclipse on Gumstix for new users and HelloWorld in Java.
This does not explain the game of MineSweeper, rather just lets use utilize the code to see an example of the graphical possibilities using an Overo COM.
- Create a new Project in Eclipse
- File -> New Project -> Java Project
- Create a class Main Class
- Copy and paste the following code to that class:
<pre> import java.awt.BorderLayout; import java.awt.Color; import java.awt.event.ActionEvent; import java.awt.event.ActionListener;
import javax.swing.JButton; import javax.swing.JColorChooser; import javax.swing.JFrame; import javax.swing.JOptionPane;
public class MainClass {
public static void main(String args[]) {
JFrame f = new JFrame("JColorChooser Sample");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
final JButton button = new JButton("Pick to Change Background");
ActionListener actionListener = new ActionListener() {
public void actionPerformed(ActionEvent actionEvent) {
Color initialBackground = button.getBackground();
Color background = JColorChooser.showDialog(null,
"JColorChooser Sample", initialBackground);
if (background != null) {
button.setBackground(background);
}
}
};
button.addActionListener(actionListener);
f.add(button, BorderLayout.CENTER);
f.setSize(300, 200);
f.setVisible(true);
}
}</pre>
- Create a class MineSweeper (Capital S!)
- Copy and paste the following code to that class:
