Ahsan,

I have implemented user interfaces like those, and my recommendation is to use/extend the ImageWindow class. So you can add stuff to the ImagePlus window while keeping the normal use of it.

As ImageWindow is AWT, you might experiment some problems if you use SWING components. I try to stay in AWT whenever it's possible, but if not (once I needed to use a JTabbedPane), try to place your swing components in a Panel, and then add that panel to the imagewindow.

I have adapted the following code from one of my recent plugins (where users had to select an area, and after that, a point inside the sub-image). Try it, and feel free to use it if you like this "style".


public class CropTest {

    public static void main(String args[]) {
        new ImageJ();
        IJ.run("Clown (14K)");

        JFrame frame = new JFrame("Crop TEST");

        JButton button = new JButton("Crop");
        button.addActionListener(new ActionListener() {

            public void actionPerformed(ActionEvent ae) {
                crop();
            }
        });

        frame.add(button);

        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

    private static void crop() {
        final ImagePlus imp = WindowManager.getCurrentImage();

        if (imp != null) {
            final Roi roi = imp.getRoi();
            if (roi != null) {
                if (roi.isArea()) {
                    // Gets CenterOfMass from image ROI
                    final ImagePlus subImp = new ImagePlus("selected region", imp.getProcessor().crop());
                    subImp.copyScale(imp);  // Copies calibration info: pixels size, etc.

                    // Adds a button to store points.
                    Button bOk = new Button("Close");
                    bOk.addActionListener(new ActionListener() {

                        @Override
                        public void actionPerformed(ActionEvent ae) {
                            subImp.close();
                        }
                    });

                    // Creates a new window as it will be null until "show()",
                    ImageWindow window = new ImageWindow(subImp);
                    // Adds button.
                    window.add(bOk);
                    window.pack();

                    subImp.show();
                } else {
                    IJ.error("ROI is not an area.");
                }
            } else {
                IJ.error("No ROI selected.");
            }
        } else {
            IJ.error("There are no images open.");
        }
    }
}
