How to right-justify icon in a JLabel?

Question

For a JLabel with icon, if you setHorizontalTextPosition(SwingConstants.LEADING), the icon is painted right after text, no matter how wide the label is.

Answer 1

I found a much easier way to do this. I needed to have this kind of layout in a JTable, and did the right justification by getting the text width and then manually setting the width between the text and the icon. I subclassed a DefaultTableCellRenderer for my JTable

public class FixedWidthRenderer extends DefaultTableCellRenderer 
{
    ...
    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, 
        boolean isSelected, boolean hasFocus, int row, int column)
    {
        ...
        FontMetrics met = super.getFontMetrics(super.getFont());
        int width = met.stringWidth(super.getText());                
        super.setIconTextGap(DESIREDWIDTH - width); 
        ...
    }
}

Works great!
And yes, for real code one should check that the text width is not bigger than the DESIREDWIDTH.

For automatic right-alignment without a fixed width that works with columns of variable width:

    @Override
    public void setBounds(int x, int y, int width, int height) {
        super.setBounds(x, y, width, height);
        if (getIcon() != null) {
            int textWidth = getFontMetrics(getFont()).stringWidth(getText());
            Insets insets = getInsets();
            int iconTextGap = width - textWidth - getIcon().getIconWidth() - insets.left - insets.right - PADDING;
            setIconTextGap(iconTextGap);
        } else {
            setIconTextGap(0);
        }
    }
