You created your own class called Scrollbar. Change
Scrollbar scrollbar = new Scrollbar(Scrollbar.HORIZONTAL,20,0,0,100);
to
java.awt.Scrollbar scrollbar = new java.awt.Scrollbar(
java.awt.Scrollbar.HORIZONTAL, 20, 0, 0, 100
);
سؤال
Well, it was fine a few seconds before, but now when I point at the "HORIZONTAL" it always says "HORIZONTAL cannot be resolved or is not a field".I have deleted the old project and created a new project, but still get this problem. Can somebody tell me what's going on? Thanks. I'm using the eclipse. Here are the codes:
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
public class subClass14 extends Applet{
public void init()
{
Scrollbar scrollbar=new Scrollbar(Scrollbar.HORIZONTAL,20,0,0,100);
add(scrollbar);
Button up=new Button("Up");
add(up);
Button down=new Button("down");
add(down);
Button left=new Button("left");
add(left);
Button right=new Button("right");
add(right);
add(new CircleCanvas(up,down,left,right));
//add(new Scrollbar(scrollbar1,scrollbar2));
}
}
