Jbutton on top of fillRect

[Josh Reev]

I have several buttons in my applet, however in certain case i use fillRect function to draw my whole applet go black, but i want to leave one Jbutton visible.

The fillRect function hides my button, but the button comes visible if i move mouse cursor on top of it. Is it possible to keep the button on top of fillRect?

Hi Josh, in which method you use fillRect?

[Campbell Ritchie]

Why have you got the button on top of the rectangle you are filling black? What sort of Component are you drawing on? Does it have a revalidate method?

I think this discussion would sit better on our Applets forum: moving.

. . . and welcome to the Ranch

Here is some code which i hope helps clarify the issue:

the button is first created in Panel function like this:

Java Syntax (Toggle Plain Text)
class app
{
  static JPanel panel1  =  new JPanel() ;
  static boolean end = false;

class GamePanel extends JPanel
                      implements ActionListener, MouseListener
{
   static JButton  newgame     =  new  newgame( "new game" ) ;
 
public GamePanel()
   {
      setLayout( new BorderLayout() ) ;
      app.panel1.setBackground( back_color ) ;
      newgame.addActionListener( this ) ;
      app.panel1.add( newgame ) ;
      add( "South", app.panel1 ) ;

in paint function there is a check to see if screen should go black:

 public void paint( Graphics graphics )
   if (app.end)
		{
              graphics.setColor( Color.BLACK ) ;
	      graphics.fillRect (0, 0, 800, 600);
	      app.panel1.remove(newgame);
              app.panel1.add(newgame);
              app.panel1.setBackground( back_color.darker() ) ;
              app.panel1.setForeground(Color.PINK);
 	     }

public class GameApplet extends JApplet
{
   public void init()
   {
      getContentPane().add( new GamePanel() ) ;
   }
}

override paintComponent instead of paint.

@Override
protected void paintComponent(Graphics g)
{ 
        if (app.end)  
        {  
              graphics.setColor( Color.BLACK ) ;  
              graphics.fillRect (0, 0, 800, 600);  
              app.panel1.remove(newgame);  
              app.panel1.add(newgame);  
              app.panel1.setBackground( back_color.darker() ) ;  
              app.panel1.setForeground(Color.PINK);  
         }  
}

Why do you have all those static fields?

@Override
protected void paintComponent(Graphics g)
{ 
        . . .

And insert this line as the first line in paintComponent

super.paintComponent(g);

I have the static's because i have many classes in the application.

This is a solution but it doesn't really answer the question. The panel1 is left outside the rectangle if paintComponent is used.
