hi there,
well i wanna display image on my applet button from the relative path how do i do.
here is my code which i tried gave me nullpointer exception and i did put this code my applets constructor:
URL url1 = new URL(getDocumentBase().toString()+"b.gif");
ImageIcon image1 = new ImageIcon(url1);
JButton button = new JButton(image1);
Hi...
you shouldn't use .toString()... and I think getCodeBase() is better to use... it loads the images from the same directory as the applet is loaded from... and if you should use a JAR file... (which I would highly recommend!!) you should use getResource() to access the images in the JAR file...
example 1: for a simple applet with getCodeBase()
ImageIcon im1 = new ImageIcon(getImage(getCodeBase(),"b.gif"));
JButton but = new JButton(im1);
example 2: for a JAR file
URL url = this.getClass().getResource("b.gif");
JButton but = new JButton(getImage(url));
well I hope this helps!
