Hide "Files of type" label and combo box in a File Chooser

[Akino877]

Hello,

I am trying to user a File Chooser with DIRECTORIES_ONLY set. And I would like to be able to hide the "Files of type" label and the associated combo box. I wonder if there is a way to do this programmatically or by using NetBeans?

Thank you for your help.

I don't think NetBeans can be of any help here; you have to perform some
surgery on your JFileChooser. The following code snippet traverses through
all the Components of a chooser; you have to identify which ones you want to
hide and set to invisible:

JFileChooser chooser= ... ; // your chooser
hideComponents(chooser.getComponents());
...
private void hideComponents(Component[] components) {
    // traverse through the components
   for (int i= 0; i < components.length; i++) {
      if (components[i] instanceof JPanel) // traverse recursively
         hideComponents(components[i].getComponents())
      else if ( /* identify component[i] */)
         component[i].setVisible(false); // hide it
   }
}
 

The code snippet avove iterates over all components of the chooser; if it finds
a JPanel, it calls itself recursively; if it finds one of your wanted components
it simply hides it.

kind regards,

Jos

Hello,

Thank you for your help.

I tried to use the code and got a compile-time error on the line :

.....................................
hideComponents(components[i].getComponents());
......................................

saying that it could not find the symbol "getComponents()". I wonder if there is another way to get a list of subcomponents?

Thanks, again.

My bad, that line should read:

 hideComponents(((JPanel)components[i]).getComponents());
 

The component is a JPanel (it was tested in the previous if-clause) and a JPanel
does have such a method so that particular component should be cast to it.
