Try this:
import awt.Graphics;
import awt.Window;
import awt.Frame;
import awt.Color;
class GraphicsTest {
static awt.Graphics MyGraphics;
public static void main (String argv [])
{
awt.WServer MyWServer=new awt.WServer ();
MyWServer.start ();
Window MyWindow;
Frame MyFrame;
MyFrame=new Frame (MyWServer,true,false,null,300,300,Color.gray);
MyFrame.setTitle ("Graphics Test Frame");
MyWindow=new Window ( MyFrame,"Center",Color.white,200,200);
MyGraphics = new Graphics (MyWindow);
MyFrame.map ();
for (int c=1;c++<1000;); //wait till frame is setup
MyGraphics.setForeground (Color.black);
MyGraphics.fillRect (40,40,10,10);
MyGraphics.drawString ("test",10,10);
GraphicsOutput test=new GraphicsOutput (MyGraphics);
test.start ();
};
public void Draw (Graphics G)
{
MyGraphics.setForeground (Color.black);
MyGraphics.fillRect (40,40,10,10);
MyGraphics.drawString ("test",10,10);
//MyWindow.drawRect (10,10,40,40);
};
};
class GraphicsOutput extends Thread
{
Graphics MyGraphics;
GraphicsOutput (Graphics G)
{
MyGraphics=G;
};
public void run ()
{
draw (MyGraphics);
};
public void draw (Graphics G)
{
System.out.println ("Test");
};
};
