This does not look like form output to me.
Products & Versions
I am using the JDK 1.0 with NT3.51 and have problems with both the
Appletviewer and Netscape 2.0Beta6a.
Short Description
The call bounds() from an object which extend Canvas returns incorrect
values of x and y (width and height are correct).
With the enclosed test code I get the following results:
Appletviewer shows
1. tz.htm1 correctly, x = 0 , y = 23, width = 400, height = 277
2. tz1.html incorrectly, x = 104, y = 92, width = 400, height = 300
Netscape 2.0Beta3 shows
1. tz.html correctly, x=0, y = 23, width = 400, height = 277
2. tz1.html correctly, x=0, y = 0, width = 400, height = 300
Netscape 2.0Beta6a shows
1. tz.html incorrectly, x = 14, y = 157, width = 400, height = 277
2. tz1.html incorrectly, x = 14, y = 134, width = 400, height = 300

add("Center", graph);
}
}

import java.applet.*;
public class tz1 extends Applet {
GD graph;
public void init() {
graph = new GD();
setLayout( new BorderLayout() );
add("Center", graph);
}
}
GD.java
import java.awt.*;
import java.applet.*;
public class GD extends Canvas {
public void paint(Graphics g) {
Graphics lg = g.create();
Rectangle r = bounds();
System.out.println("R: x = "+r.x+" y = "+r.y);
System.out.println(" width = "+r.width+" height = "+r.height);
int border = 30;
r.x += border;
r.y += border;
r.width -= 2*border;
r.height -= 2*border;
lg.drawRect(r.x,r.y,r.width,r.height);
lg.dispose();
}
}
If I am completely out to lunch here, I would really like to know.
