Java Applet: no antialiased font in browser (but i

Question

In the AppletViewer, my Applet looks like this:

In the browser, my Applet looks like this:

As you can see, the font is not antialiased. Also the background color is different. And all the text is cutted on the right side.

What could that be?

You can also try it yourself here.

From here I tried to use this code:

System.setProperty("awt.useSystemAAFontSettings","on");
System.setProperty("swing.aatext", "true");

But that results only in this exception:

java.security.AccessControlException: access denied (java.util.PropertyPermission awt.useSystemAAFontSettings write)

Answer 1

It should work by overriding the paint method like this for each component where you want to have anti-aliasing:

static void activateAntiAliasing(Graphics g) {
    try {
        Graphics2D g2d = (Graphics2D)g;

        // for antialiasing geometric shapes
        g2d.setRenderingHint( RenderingHints.KEY_ANTIALIASING,
                              RenderingHints.VALUE_ANTIALIAS_ON );

        // for antialiasing text
        g2d.setRenderingHint( RenderingHints.KEY_TEXT_ANTIALIASING,
                              RenderingHints.VALUE_TEXT_ANTIALIAS_ON );

        // to go for quality over speed
        g2d.setRenderingHint( RenderingHints.KEY_RENDERING,
                              RenderingHints.VALUE_RENDER_QUALITY );
    }
    catch(ClassCastException ignored) {}
}

@Override public void paint(final Graphics g) {
    activateAntiAliasing(g);
    super.paint(g);
}
