Reset applet viewer code#
Note: Because some old browsers don't support 1.1, the above applet is a 1.0 version (here is the 1.0 code here's the 1.1 code). Here's an applet that simply lists all the applets it can find on this page: So that it returns only those applets that originatedįrom the same host as the applet calling getApplets. Many browsers and applet viewers implement getApplets

((Receiver)receiver).startCommunicating(this) įinding All the Applets on a Page: The getApplets Method Then you just need to have the sender give a reference to itself If you want your receiver to be able to send messages to the sender, The example applets in this page perform one-way communication. Its name is stored in a parameter named NAME.įor example, Sender gets its own name with the following code:įor more information on using getParameter, see ((Receiver)receiver).processRequestFrom(myName) compiler will let us call a Receiver method. (instead of just an Applet object) so that the Cast the receiver to be a Receiver object Use the instanceof operator to make sure the applet The Sender sends a message to the Receiver. Receiver = getAppletContext().getApplet(receiverName) Īnd that it's an instance of the correct class ( Receiver). String receiverName = nameField.getText() //Get name to search for. The Sender will find an applet named buddy In the Sender's text field labeled "Receiver name:," Some status information will appear in the Sender's window,Īnd the Receiver will confirm (with its own status string)Īfter you've read the Receiver status string, This figure has been reduced to fit on the page.Ĭlick the image to view it at its natural size.īecause some old browsers don't support 1.1,Ĭlick the Send message button of the top applet (the Sender). (passing the Sender's name as an argument). The Sender sends a message to the Receiverīy invoking one of the Receiver's methods The first, the Sender, looks up the second, the Receiver. By specifying a NAME parameter with a tag.Īlthough at least one Java-enabled browserĪnd getApplet("OLD PAL") should both find anīelow are two applets that illustrate lookup by name.By specifying a NAME attribute within the applet's tag.You can specify an applet's name in two ways: To see if one of them has the specified name.

(using the AppletContext getApplet method) So it's possible that it will not be supported by all browsers. Some browsers let applets invoke methods on other applets -Įven applets on different pages in the same browser -Īs long as all of the applets come from the same code base. Originate from the same directory on the server
