I created a Tooltip with a HTML formated text, this works fine, but I have no space between border and text. How can I set Insets or an EmptyBorder?
回答1:
Found this one article on how to change properties of Java ToolTip (background, border, etc.). It focuses on colors and border style but maybe you can use this approach for margins (insets) too.

This works for me:
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JToolTip;
import javax.swing.border.EmptyBorder;
public class tooltipinsets {
public static void main(String[] args) {
JFrame window = new JFrame();
JLabel lbl = new JLabel("Test") {
@Override
public JToolTip createToolTip() {
return createCustomToolTip();
}
};
window.add(lbl);
lbl.setToolTipText("<html><b><i>This is the tooltip</i></b></html>");
window.pack();
window.setLocationRelativeTo(null);
window.setVisible(true);
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public static JToolTip createCustomToolTip() {
JToolTip tip = new JToolTip();
tip.setBorder(new EmptyBorder(10, 10, 10, 10));
return tip;
}
}

I've read this article and think it's helpful for you. It suggests setting Margin from a Component and like-wise features...
