Disabling a JPanel

[Esteban]

So my problem is something like that:

I have a class that extends JPanel. After an event occurs I want to disable this panel.

My code is something like that

public class GamePanel extends JPanel
{
   ...

  enableTree ( this, false )

  private void enableTree(Container root, boolean enable) 
 {
	System.out.println ( "in" );
	System.out.println ( "" + root );
	Component[] com = root.getComponents();  
  
	for (int a = 0; a < com.length; a++) {
		System.out.println ( a );  
		com[a].setEnabled(enable);  
	}
 }
}

You get the idea I think :-)

If it is any help, I should tell you that I use the method enableTree in another class too and it works just fine. Thing is that this class is like

 public class Foo
{
  JPanel fooPanel;
  ....
}

I 've put some prints inside the method and the conclusion is that it doesn't get inside the for loop ( it has no components as to say? :P )

Thanks anyway :)

Cheers

This won't work if you have components inside of components (nesting of components) as will occur in most moderate to complex GUI's. To solve this, you need to create a method to disable components recursively. Hang on a sec and I'll show you...

edit:

something like this (which I placed in another recent post):

   public static void setEnabledAll(Container container, boolean enabled) {
      Component[] components = container.getComponents();
      if (components.length > 0) {
         for (Component component : components) {
            component.setEnabled(enabled);
            if (component instanceof Container) { // has to be a container to contain components
               setEnabledAll((Container)component, enabled); // the recursive call
            }
         }
      }
   }
