Look & Feel, in JComboBox

Question

How would I allow the user to choose his preferred Look & Feel from a JComboBox, and make him press an 'OK button' to confirm his choice? I've tried some stuff, but I can't get it to work... ANY code would be extremely helpful, and I would be grateful for any suggestions.

Hi,
Create a String to hold the names of the different look n feels
//create String to hold names of the different Look and feels
String[ ] LAFNames = new String[ ] {"System Default", "Windows", "Java", "Mac OS", "Motif"};
//String to hold users selection
String storeLAFChoice;
//or can use int
int storeLAFSelection;
//Actual JComboBox
JComboBox LAFCB;
//in your constructor initialise the JCB
  LAFCB = new JComboBox(LAFNames);
  LAFCB.setSelectedIndex(0);
  LAFCB.setMaximumRowCount(5);
  //create your frame/window
//within your frame/window
//storeLAFChoice =LAFCB.getSelectedItem().toString();
//can use above with something like
// if( storeLAFChoice.equals("Motif") ) { do motif Look n Feel }...
storeLAFSelection = LAFCB.getSelectedItemIndex();
switch(storeLAFSelection)
  //if sys def has been chosen
  case 0: try{  UIManager.setLookAndFeel(      
  UIManager.getSystemLookAndFeelClassName() );
  SwingUtilities.updateComponentTreeUI(the name of your main panel /frame here);
  }//ends try
  catch(Exception ex) {    } 
  //if  windows chosen
  case 1:  try{   UIManager.setLookAndFeel
("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
SwingUtilities.updateComponentTreeUI(your main panel here);
}//ends try
catch(Exception ex) { //set to system default Look n feel }
  case n ....
  //for java:
  ...("javax.swing.plaf.metal.MetalLookAndFeel");...
  //for Mac OS
  ...("javax.swing.plaf.mac.MacLookAndFeel");...
  //for Motif
  ...("com.sun.java.swing.plaf.motif.MotifLookAndFeel");...
}//ends switch
...I know this is very much a bits and pieces implementation, but good luck,
Has.
