GAMES LESSON FOURTEEN: Mouse Cursor
You can change the type of cursor you use in your applet. This might be
useful for a number of reasons. Take a look at the cursor options by
clicking a few times on the sample applet.
The cursor options are listed below in an array of int values.
<![CDATA[
int cc[] = { Cursor.CROSSHAIR_CURSOR, Cursor.DEFAULT_CURSOR,
Cursor.HAND_CURSOR, Cursor.TEXT_CURSOR, Cursor.WAIT_CURSOR };
]]>
You use the following command to load a cursor.
<![CDATA[
setCursor(new Cursor(cc[i]));
]]>
MCursor.java
<![CDATA[
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class MCursor extends Applet{
Dimension d;
Image offI;
int cc[] = { Cursor.CROSSHAIR_CURSOR, Cursor.DEFAULT_CURSOR,
Cursor.HAND_CURSOR, Cursor.TEXT_CURSOR, Cursor.WAIT_CURSOR };
int i;
public void init(){
d = getSize();
offI=createImage(d.width,d.height);
this.addMouseListener(new MouseAdapter(){
public void mouseClicked(MouseEvent m) {
setCursor(new Cursor(cc[i]));
i++;
i%=cc.length;
repaint();
}
});
}
public void update(Graphics g){
paint(g);
}
public void paint(Graphics g){
Graphics offG = offI.getGraphics();
offG.setColor(Color.yellow);
offG.fillRect(0,0,d.width,d.height);
offG.setColor(Color.black);
offG.drawString("Click to change cursor.", 10, d.height-5);
g.drawImage(offI, 0,0, this);
}
}
