I tested it with 7.
Likewise, the display of objects in a JList is handled by an object called Renderer. For a JList, a renderer is provided by default. So, how does this renderer work? The renderer is responsible for displaying all the elements in the list.
The renderer actually calls the toString method on the object and uses that string value in the display. As we did not override toString method in our instance class Country, the Object's toString is invoked and that is what is displayed.
Remember that, the class Object is the top-most class in Java's class hierarchy and all classes extend Object by default.
Implementing toString Let us now implement toString in our class. We would like to display the name of the country in the list. So, our toString can simply return the name: Output with toString Implementation 6. Developing a Custom Renderer The above implementation is good enough for most cases.
However, what about custom painting? In our case, what if we would like to display the country's flag alongside the name of the country? In such a case, we will have to write our own custom renderer. To develop a custom renderer, we should write a class that implements ListCellRenderer interface.
This interface has one method getListCellRendererComponent. This method expects a component to be returned back. This component should handle the display of the item. So, we can have this class extend JLabel as a JLabel can display both icon and text.
These icons would be simple. Let us now write the code for the renderer: This interface has a single method getListCellRendererComponent which returns a java. So, basically, we can return a Swing component from this method which does the rendering.
Note the usage of parameterized syntax when implementing the interface.HTML's multimedia features allow authors to include images, applets (programs that are automatically downloaded and run on the user's machine), video clips, and other HTML documents in their pages.
For example, to include a PNG image in a document, authors may write: To address these issues, HTML 4. The easiest way to write an Applet is to start with a working one, alt= You need Java to run this Applet: what to display if no Java interpreter available. image to display if no Java interpreter available.
You need Java to run this Applet. Integrating an Applet in a Web Application. An applet is a program written in the Java programming language that can be included in an HTML page, much in the same way an image is included in a page.
Feb 22, · Java Applet not displaying image? I'm attempting to make a simple menu applet and have been frustrated because of the lack of ability for the applet to display an image. It will load the image; I have checked in the Java kaja-net.com: Resolved. When you write many programs you notice that most tasks come back often, and that you can solve that by writing libraries.
It will make use of nice image buttons and it will show a loading bar. */ import kaja-net.com*; import kaja-net.com*; /* Loadable is required for RealMedia so that it know that this code. 10/18/ Update – From a comment below.
I haven’t tested this as I’ve given up on Java completely. I just wanted to leave a note with how i got this working (there was lots of info in this thread but it was hard to find a clear step by step with success).
