When resizing text to fill a JLabel the text sometimes "jiggles", how do I fix this?

Show all headers | View raw

In my GUI program, I have a thread with a while loop that resizes the text to fit into the various JLabels and JButtons that are on it. But sometimes when the text is a certain width it will get bigger and smaller. For example, it will have text in the font size 26, it loops and resizes it to 20. Then it loops again and changes it back to 26, creating a "jiggling" effect.

Here is what I have:

public static Font getMaxFontSize(Component comp, String text) {
	Font compFont = comp.getFont();
	String compText = text;
	int stringWidth = questionLabel.getFontMetrics(compFont).stringWidth(compText);
	int compWidth = comp.getWidth()-75;
	
	if (stringWidth == 0) {
		stringWidth++;
	}
	double widthRatio = (double)compWidth / (double)stringWidth;
	
	int newFontSize = (int)(compFont.getSize() * widthRatio);
	int compHeight = comp.getHeight();
	
	int fontSizeToUse = Math.min(newFontSize, compHeight);
	
	if (fontSizeToUse < 1) {
		return new Font(compFont.getName(), Font.PLAIN, 1);
	}
	return new Font(compFont.getName(), Font.PLAIN, fontSizeToUse);
}

Does anyone know why it is doing this, and how I could fix it?

Thanks!
