Displaying Short Status Strings

All browsers allow applets to display a short status string. All applets on the page, as well as the browser itself, share the same status line.

You should never put crucial information in the status line. If many users might need the information, it should instead be displayed within the applet area. If only a few, sophisticated users might need the information, consider displaying the information on the standard output (see Displaying Diagnostics to the Standard Output and Error Streams).

The status line is not usually very prominent, and it can be overwritten by other applets or by the browser. For these reasons, it's best used for incidental, transitory information. For example, an applet that loads several image files might display the name of the image file it's currently loading.

Applets display status lines with the showStatus method, inherited in the JApplet class from the Applet class.

Here's an example of its use:

showStatus("MyApplet: Loading image file " + file);

Note:  Please don't put scrolling text in the status line. Browser users find such status line abuse highly annoying!
