JCheckBox with Image

Question

How can I have a checkbox group with an image?

I use:

for (String testata : listaTestate) {
        JCheckBox checkbox = new JCheckBox();
        ImageIcon imgTestata = new ImageIcon("src/img/"+testata+".png");
        checkbox.setName(testata);
        checkbox.setBackground(new Color(194, 169, 221));
        checkbox.setSelected(true);
        testate.add(checkbox);
        JLabel label = new JLabel(imgTestata);
        label.setBackground(new Color(194, 169, 221));
        label.setPreferredSize(new Dimension(500, 50));
        testate.add(label);
    }

but there is a lot of space between the ImageIcon and the JCheckBox.

Don't use `src/img/...`, `src` won't exist once the problem is deployed. Use `getClass().getResource("/img/...")` instead — MadProgrammer, Jan 12 '15 at 21:47
Do you want each check box to have an image or just the group? — MadProgrammer, Jan 12 '15 at 21:48
Each ceckboh have a different image (based on the String testata) — Razzo, Jan 12 '15 at 23:26

Without knowing the layout manager, it's difficult to be 100%, but if I was doing this, I might use a GridBagLayout...

testate.setLayout(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridy = 0;
gbc.insets = new Insets(4, 4, 4, 4);
gbc.anchor = GridBagConstraints.WEST;
for (String testata : listaTestate) {
    gbc.gridx = 0;
    JCheckBox checkbox = new JCheckBox();
    ImageIcon imgTestata = new ImageIcon(getClass().getResource("/img/"+testata+".png"));
    checkbox.setName(testata);
    checkbox.setBackground(new Color(194, 169, 221));
    checkbox.setSelected(true);
    testate.add(checkbox, gbc);
    gbc.gridx++;
    JLabel label = new JLabel(imgTestata);
    label.setBackground(new Color(194, 169, 221));
    testate.add(label, gbc);
    gbc.gridy++;
}

the space happens because you call .setPreferredSize(new Dimension(500, 50)); on each label instance created on your loop,which resulting wide label, so remove it and the result will just fine.

oh ya and calling .getClass().getResource() is preferred , just like @MadProgrammer said it to you. – Fevly Pallar Jan 12 '15 at 22:45
without label.setPreferredSize(new Dimension(500, 50)); I have the same problem. :( – Razzo Jan 12 '15 at 23:26

@Razzo, it must be it, because I tested your code also. When remove it the space between checkbox & icon is dissappeared, or perhaps you use some layouts to manages the space like GridLayout maybe.. – Fevly Pallar Jan 13 '15 at 00:10
