Button in Graphic
My last question was probably to long so I decide to change it I looking for way to make button or listener that make this graphics shows after pressing I just starting with programming so I don't know how to do it exactly. Any help will be appreciated:)
import java.applet.Applet;
import java.awt.*;
//The applet code
public class Main extends Applet {

setSize(2000,500);
}
public void paint(Graphics g) {

//Hat
g.setColor(Color.blue);

In order to get what you want you need both a button and a listener. You will need a JButton and an ActionListener. Below you will see some code I wrote to create a blackjack game that used JButtons and ActionListeners. The ActionListeners will be linked to your JButtons so that when the button is clicked, the ActionListenerexecutes whatever you want done.
JButton Quit = new JButton("Quit");
Quit.addActionListener(new QuitListener());
CenterSub.add(Quit, BorderLayout.SOUTH);
Let's start with the first line of the snippet. I declared a JButton called Quit on the right side of the equals. On the left side I finished the initialization and gave the JButton text to be displayed on the actual button. In this case the button will read "Quit" once the program is run. The second line adds an ActionListener to the JButton so that once the button is clicked, the code in the ActionListener will execute. In the parenthesis on the second line I call the new ActionListener QuitListener. When I write the Listener code, this will be its name. The last line shows where I added the button on my JPanel. I called the JPanel name (CenterSub), then passed in the name of the button and where I wanted it to be located as parameters.
private class QuitListener implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
System.exit(0);
}
}
This snippet is the definition for the QuitListener that I added to the JButton in the first snippet. QuitListener implements the interface ActionListener which allows me to define the actionPerformed(ActionEvent e) method to do what I want. The ActionEvent is the player clicking on the "Quit" button. When the button is clicked, the method actionPerformed will execute and call System.exit(0) which terminates the program, thus allowing the player to quit the game.
So, to wrap it up, to achieve what you want achieved, create a JButton, an ActionListener and in the ActionListener definition for the actionEvent method, call the paint method that you have defined. For further assistance, I highly suggest checking out the Jbutton API as well as any other APIs that you may need.
This the JButton API.
This is my first time answering a question, so I hope this helped you gain some insight into what you need.

Start by at least using the Swing API. I'd also question the need to use applets and would recommend using window based classes instead, they are whole lot simpler to deal with.
Start by creating a custom component extending from something like JPanel, override it's paintComponent method and place you custom painting within.
Create another JPanel and assign it a BorderLayout and add this to your main container, this will act as a place holder for the "robot pane"
Create a JButton, using a BorderLayout, place both the "content pane" and button in the top level container (in your case, the applet)
Attach an ActionListener to the button, when it is triggered, create a new instance of the "robot pane" and place it within the "content pane"
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JApplet;
import javax.swing.JButton;
import javax.swing.JPanel;
public class Main extends JApplet {
private JPanel content;
public void init() {
setLayout(new BorderLayout());
content = new JPanel(new BorderLayout()) {
@Override
public Dimension getPreferredSize() {
return new Dimension(500, 2000);
}
};
add(content);
JButton btn = new JButton("Show me the robot");
add(btn, BorderLayout.SOUTH);
btn.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
btn.setEnabled(false);
RobotPane botPane = new RobotPane();
content.add(botPane);
revalidate();
repaint();
}
});
}
public class RobotPane extends JPanel {
@Override
public Dimension getPreferredSize() {
return new Dimension(500, 2000);
}
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);

use the jframe class that is built in. u can set.contentpane(visible, false) put your graphic into the content pane. then use a jbutton to set the content pane to visible when clicked
