/**
|
|
|
|
* <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>
|
2009-05-28 14:17:04 -04:00
|
|
|
* The downloaded jars are extracted to the users temporary directory - and if enabled, cached for
|
2007-06-10 16:30:03 -04:00
|
|
|
* faster loading in future uses.
|
|
|

AppletLoader: Parameters boxbgcolor, boxfgcolor and boxerrorcolor have been added. Previous parameters al_bgcolor, al_fgcolor and al_errorcolor have been removed. Unlike the previous color support now you can specify the color as a string name of any AWT Color ("red", "blue", "yellow", etc), RGB format (0-255, e.g. "255,0,0") or html HEX color (must use leading #, previous didn't need to have the # e.g. "#FF0000"). This is to match the color support of boxbgcolor and boxfgcolor of the java plugin, so now the color is set and appears before the appletloader is even loaded.
2010-07-04 10:35:41 -04:00
|
|
|
* <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>

AppletLoader: Parameters boxbgcolor, boxfgcolor and boxerrorcolor have been added. Previous parameters al_bgcolor, al_fgcolor and al_errorcolor have been removed. Unlike the previous color support now you can specify the color as a string name of any AWT Color ("red", "blue", "yellow", etc), RGB format (0-255, e.g. "255,0,0") or html HEX color (must use leading #, previous didn't need to have the # e.g. "#FF0000"). This is to match the color support of boxbgcolor and boxfgcolor of the java plugin, so now the color is set and appears before the appletloader is even loaded.

AppletLoader: Parameters boxbgcolor, boxfgcolor and boxerrorcolor have been added. Previous parameters al_bgcolor, al_fgcolor and al_errorcolor have been removed. Unlike the previous color support now you can specify the color as a string name of any AWT Color ("red", "blue", "yellow", etc), RGB format (0-255, e.g. "255,0,0") or html HEX color (must use leading #, previous didn't need to have the # e.g. "#FF0000"). This is to match the color support of boxbgcolor and boxfgcolor of the java plugin, so now the color is set and appears before the appletloader is even loaded.
