Patch to fix EmphasizedLabel in OpenJDK 7

[Steve McLeod]

The rendering in EmphasizedLabelUI doesn't work properly in OpenJDK 7 on Mac. It uses the wrong font and doesn't anti-alias.

I spent too much time this weekend on creating a work-around, before finally coming up with a simple solution. 

The patch attached will fix the problem.

Regards,

Another approach is to manually turn on anti aliasing when drawing the emphasized label:

    protected void paintEnabledText(JLabel label, Graphics g, String s, int textX, int textY) {

        final Graphics2D g2 = (Graphics2D) g;

        g2.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);

        ....

   }

and

    protected void paintDisabledText(JLabel label, Graphics g, String s, int textX, int textY) {

        final Graphics2D g2 = (Graphics2D) g;

        g2.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);

        ....

   }

I tried understanding the Oracle code to find the root of the problem, but alas, understanding the core Swing rendering code is not an easy undertaking.
