Loading picture before the using java applet / progress bar or waiting message ?
|

| Mark Richards 2004-10-07, 8:57 pm |
| An applet on one of my pages uses a big picture as background.
I want to load it before the applet and the rest of the html source.
By doing this I want to avoid that the pane of the applet is grey during the
load of the picture.
How do I do that?
Or even better: How can I display something like a progress bar or at least a temporary, self removing
message (dialog) "Please wait a few second..." until the picture and the applet were loaded completely?

You can't.

Use a MediaTracker instance and a progress bar that follows the
MediaTracker's progress.
Please do not cross-post as you are doing.

2. Make it smaller. Images can be shrunk in bytes a
variety of ways.

If you jar your applet, you can use the 'icon' element of
type 'splash' in the jnlp to launch the applet using Java
Webstart. It should use that for the splash screen image.
(obvipously your splash will say 'wait a few moments')

Alternately, I have a splash screen that will work for simple
applets in JVM's back to the Symantec 1.1.5 and MS 1.1.4.
