Modal JDialog in an applet

To create a modal JDialog, you have to pass a reference to a parent Frame or JDialog. In applets, this may be a problem, since you create no Frames. However, every Java plugin implementation known to me actually creates a Frame and puts the applet in it. So, just look it up. Add this method to your applet and use it when instantiating modal JDialogs.

  private Frame findParentFrame(){ 
    Container c = this; 
    while(c != null){ 
      if (c instanceof Frame) 
        return (Frame)c; 
 
      c = c.getParent(); 
    } 
    return (Frame)null; 
  }
