Here is my class that tries to use a JRootPane to attach an SVG image as a background image and then add JLabels on top. It doesn't work and just displays the SVG image. If I add the glassPane to the JFrame's contentPane then all I get is a grey nothingness. Why won't the glassPane display the labels? Where am I going wrong? All I want is a set of JLabels with an SVG image in the background (not the background of the labels but behind the labels so the labels are on top of this image).
public class TestBackgroundSVG
{
public static void main(String args[])
{
JFrame f = new JFrame("Test");
Container c = f.getContentPane();
JLabel lab1 = new JLabel("label1");
JLabel lab2 = new JLabel("label2");
JSVGCanvas canvas = new JSVGCanvas();
canvas.setURI("http://localhost:8081/SVGImages/Background.svg");
JRootPane rootPane = new JRootPane();
rootPane.setContentPane(canvas);
rootPane.setGlassPane(new JPanel());
JPanel glassPane = (JPanel)rootPane.getGlassPane();
glassPane.add(lab1);
glassPane.add(lab2);
glassPane.setOpaque(false);
c.add(rootPane);
f.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e){
System.exit(0);
}
});
f.pack();
f.setSize(200,200);
f.setVisible(true);
}
}
any help would be great
cheers
Claire :)
