There is not a lot to explain. Just see the MCVE/image below:
public class FontExample extends JFrame {
private static final Font FONT = new Font("Calibri", Font.PLAIN, 14);
public FontExample() {
super("");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLayout(new FlowLayout());
JLabel withoutHtml = new JLabel("hello stackoverflow");
withoutHtml.setFont(FONT);
withoutHtml.setBorder(BorderFactory.createLineBorder(Color.red));
add(withoutHtml);
JLabel withHtml = new JLabel("<html><body style='vertical-align:top;'>hello stackoverflow");
withHtml.setBorder(BorderFactory.createLineBorder(Color.green));
withHtml.setFont(FONT);
add(withHtml);
setLocationByPlatform(true);
pack();
}
public static void main(String[] args) {
SwingUtilities.invokeLater(() -> {
//Make sure Calibri font is installed
if (!"Calibri".equals(FONT.getFamily())) {
System.err.println("Font calibri is not installed.");
System.exit(1);
}
new FontExample().setVisible(true);
});
}
}
The green one is with the <html>
tag. Is there a way to fix it? And by fix, I mean to make it like the left one, without this stupid space?
It does not seem to happen with any other font (I tested 2-3 more). I am on Java 8 with Windows 7 and Windows 10.
I tried to add padding at bottom:
JLabel withHtml = new JLabel("<html><body style='padding-bottom:5px'>hello stackoverflow");
and as expected what I get is this:
which a) will screw the alignment of other components in the same container (bad for UI purposes) and b) I will have to hard code a lot of values since 5 since to be the proper for font size 14. But for other font size, it needs another value.
@Andrew Thomson in comments said to use the HTML format for all JLabels. But then, if they are next to another text-based component like a JTextField
, I get this:
which obviously, is bad too.
UPDATE
Also, I tried to download Calibri font (among with variations like "Calibri Light", etc) somewhere from the web and install it as described in this question. I do not know if that "Overrides" the existing one, but I had the same result.
