<div class="block"><p>
The AppletLoader enables deployment of LWJGL to applets in an easy
and polished way. The loader will display a configurable logo and progressbar
while the relevant jars (generic and native) are downloaded from a specified source.
</p>
<p>
The downloaded jars are extracted to the users temporary directory - and if enabled, cached for
faster loading in future uses.
</p>
<p>
The following applet parameters are required:
<ul>
<li>al_main - [String] Full package and class the applet to instantiate and display when loaded.</li>
<li>al_jars - [String] Comma separated list of jars to download.</li>
<p>
<li>al_windows - [String] Jar containing native files for windows.</li>
<li>al_linux - [String] Jar containing native files for linux.</li>
<li>al_mac - [String] Jar containing native files for mac.</li>
<li>al_solaris - [String] Jar containing native files for solaris.</li>
<li>al_freebsd - [String] Jar containing native files for freebsd.</li>
</ul>
</p>
<p>
Additionally the following parameters can be supplied to tweak the behaviour of the AppletLoader.
<ul>
<li>al_cache - [boolean] Whether to use cache system. <i>Default: true</i>.</li>
<li>al_version - [int or float] Version of deployment. If this is specified, the jars will be cached and
reused if the version matches. If version doesn't match all of the files are reloaded.</li>
<li>al_debug - [boolean] Whether to enable debug mode. <i>Default: false</i>.</li>
<li>al_min_jre - [String] Specify the minimum jre version that the applet requires, should be in format like 1.6.0_24 or a subset like 1.6 <i>Default: 1.5</i>.</li>
<li>al_prepend_host - [boolean] Whether to limit caching to this domain, disable if your applet is hosted on multiple domains and needs to share the cache. <i>Default: true</i>.</li>
<li>al_lookup_threads - [int] Specify the number of concurrent threads to use to get file information before downloading. <i>Default: 1</i>.</li>
<p>
<li>al_windows64 - [String] If specified it will be used instead of al_windows on 64bit windows systems.</li>
<li>al_windows32 - [String] If specified it will be used instead of al_windows on 32bit windows systems.</li>
<li>al_linux64 - [String] If specified it will be used instead of al_linux on 64bit linux systems.</li>
<li>al_linux32 - [String] If specified it will be used instead of al_linux on 32bit linux systems.</li>
<li>al_mac32 - [String] If specified it will be used instead of al_mac on 64bit mac systems.</li>
<li>al_mac64 - [String] If specified it will be used instead of al_mac on 32bit mac systems.</li>
<li>al_macppc - [String] If specified it will be used instead of al_mac on PPC mac systems.</li>
<p>
<li>boxbgcolor - [String] any String AWT color ("red", "blue", etc), RGB (0-255) or hex formated color (#RRGGBB) to use as background. <i>Default: #ffffff</i>.</li>
<li>boxfgcolor - [String] any String AWT color ("red", "blue", etc), RGB (0-255) or hex formated color (#RRGGBB) to use as foreground. <i>Default: #000000</i>.</li>
<p>
<li>al_logo - [String Path of of the logo resource to paint while loading.<i>Default: "appletlogo.gif"</i>.</li>
<li>al_progressbar - [String] Path of the progressbar resource to paint on top of the logo, width clipped by percentage.<i>Default: "appletprogress.gif"</i>.</li>
<p>
<li>lwjgl_arguments - </li> [String] used to pass LWJGL parameters to LWJGL e.g. ("-Dorg.lwjgl.input.Mouse.allowNegativeMouseCoords=true -Dorg.lwjgl.util.Debug=true").</li>
