How to resize a JFile Chooser

I am designing a file browser using Java Swing, and here is what I have so far:

I have a JFileChooser in a panel, however it stays the same size when I reshape the window. However, I want to make it look like this:

Without the items inside resizing of course.

Is it possible to make the actual Browser box resize along with the form?

EDIT: I do not want a popup JFileChooser, the JFileChooser is INSIDE the Frame.

Solution

  • You don't need to add the file chooser to a panel - if you just initialize one and set it visible, it will automatically be resizable.

    JFileChooser chooser = new JFileChooser();
chooser.setVisible(true);
int returnVal = chooser.showOpenDialog(null);
if (returnVal == JFileChooser.APPROVE_OPTION) {
    //continue your code here

    To incorporate the file chooser into the panel, try this:

    JFrame frame = new JFrame();
JPanel panel = new JPanel(new BorderLayout());
JFileChooser chooser = new JFileChooser();
panel.add(chooser);
frame.add(panel);
frame.pack();
frame.setVisible(true);

    I'm not sure how you used the BorderLayout before but this code works perfectly on my computer.
