The FlowLayout Manager

Our program will look better if it uses the FlowLayout manager. The FlowLayout manager puts components into the frame row by row in the order they are added. (Later on we will add more than one component). It also picks reasonable sizes for components. Here is how you ask for this manager:

import java.awt.*;
. . .
 
public class ButtonDemo extends JFrame
{
  Button bChange; 

  buttonDemo()     
  {
    bChange = new Button("Click Me!"); 
    // choose the layout manager
    getContentPane().setLayout( new FlowLayout() ); 
    getContentPane().add( bChange );
  }

  public static void main ( String[] args )
  {
    ButtonDemo frm = new ButtonDemo();
      . . . . .
  }
}

The FlowLayout manager is part of the java.awt package.
