Thank you. It is working. I did it more or less as suggested. Below is
my code fragments:
// Initialise comboBox with teams & set initial selection.
String[] imgs={"Albania.gif", "Austria.gif", "Cambodia.gif",
"Croatia.gif", "Lebanon.gif", "Malaysia.gif"};
String[] teams=removeFileExtension(imgs);
final JComboBox teamsChoice=new JComboBox(teams);
teamsChoice.setSelectedIndex(teams.length - 1);
// Set initial icon in display label.
String path="/images/flagicons";
final ImageIcon[] flags=createImageIcons(path, imgs);
displayLabel.setIcon(flags[flags.length - 1]);
// Event handling for comboBox. Changes icon as per comboBox
selection.
teamsChoice.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
if(e.getActionCommand().equals("comboBoxChanged")){
displayLabel.setIcon(flags
[teamsChoice.getSelectedIndex()]);
}
}
});
However, I seek to improve how comboBox is populated.
// This is not very elegant. What can I use to seek a directory of
images, and retrive filenames in it to populate the comboBox?
String[] imgs={"Albania.gif", "Austria.gif", "Cambodia.gif",
"Croatia.gif", "Lebanon.gif", "Malaysia.gif"};
String[] teams=removeFileExtension(imgs);
final JComboBox teamsChoice=new JComboBox(teams);
teamsChoice.setSelectedIndex(teams.length - 1);
