Okay, I have a Jpanel which is shown as white in the below image using an overlay layout. It holds a ScrollPane holding an image (“No Image Available”) and a JButton (“Comment”).

enter image description here

I want to position this button in the bottom right hand corner of the JPanel. I have tried multiple layout approaches and I cant seem to get it to work. At most the button moves about 3/4 of the way South-East and I have no idea why.

Any help is greatly appreciated..

    There are a lot of possible solutions using different layout managers. I don’t know the OverlayLayout, but I like WindowBuilder Pro (free): https://developers.google.com/java-dev-tools/wbpro/ for help with Swing design.

    Using it, I wrote a SpringLayout implementation of your question (SpringLayout seems like a pain to deal with without a GUI-builder).

    JPanel panel = new JPanel();
SpringLayout sl_panel = new SpringLayout();
panel.setLayout(sl_panel);

JButton button = new JButton("Comments");
sl_panel.putConstraint(SpringLayout.SOUTH, button, 0, SpringLayout.SOUTH, panel);
sl_panel.putConstraint(SpringLayout.EAST, button, 0, SpringLayout.EAST, panel);
panel.add(button);

JScrollPane scrollPane = new JScrollPane();
sl_panel.putConstraint(SpringLayout.NORTH, scrollPane, 5, SpringLayout.NORTH, panel);
sl_panel.putConstraint(SpringLayout.WEST, scrollPane, 3, SpringLayout.WEST, panel);
sl_panel.putConstraint(SpringLayout.SOUTH, scrollPane, 3, SpringLayout.SOUTH, panel);
sl_panel.putConstraint(SpringLayout.EAST, scrollPane, 3, SpringLayout.EAST, panel);
panel.add(scrollPane);

JLabel lblNewLabel = new JLabel();
lblNewLabel.setIcon(new ImageIcon(foo.class.getResource("sSdA3.png")));
scrollPane.setViewportView(lblNewLabel);

    Here’s a picture of the code running:

    enter image description here

    You can see the button (mine, not the picture of yours…) is floating above the scroll-pane in the bottom. We could adjust the margins above so the button wasn’t floating on top of the scroll-bars, but this is just to show you where it is on the z-axis.
