ch.aplu.util
Interface GPrintable

public interface GPrintable

Interface for printing on an attached printer. Normally an application derives from GPanel (or uses a GPanel) and implements this interface. draw() should contain all drawing operations into the GPanel. The printing occures, when GPanel's print() is called.

Example:
import ch.aplu.util.*;

public class PrintTest extends GPanel implements GPrintable
{
public PrintTest()
{
draw(); // Draw on screen
print(this); // Draw on printer
}

public void draw()
{
move(0, 0);
draw(0, 1);
draw(1, 1);
draw(1, 0);
draw(0, 0);
line(0, 0, 1, 1);
line(0, 1, 1, 0);
}

public static void main(String[] args)
{
new PrintTest();
}
}

void draw()
