JDialog allows the user to change the width of the dialog

Does anyone know if it is possible to limit how a user resizes a JDialog?

I know that I can call the setResizible (boolean) method and disable or allow the user to resize the JDialog, but is there a way to limit the user to resize the window, but let him resize it?

The dialog that I create looks funny if it grows vertically, but a horizontally growing component can be useful to the user.

Thanks in advance.

You can add ComponentListenerto JDialog and check componentResizedif the height has changed. This can be implemented by extending the JDialog class as follows:

public class Dialog extends javax.swing.JDialog {

    public Dialog(java.awt.Frame parent, boolean modal) {
        super(parent, modal);
        initComponents();
        final int h = getHeight();
        addComponentListener(new ComponentAdapter() {

            @Override
            public void componentResized(ComponentEvent e) {
                Rectangle b = getBounds();
                if (b.height != h) {
                    b.height = h;
                    setBounds(b);
                }
                super.componentResized(e);
            }
        });
    }
}
