Method Detail

getSkinDir

public static java.lang.String getSkinDir()

Return the skin dir.

Returns:

the skin dir

public static void cacheImgs(java.lang.String skinImgDir,
                             java.lang.Iterable<java.lang.String> baseImageURLs)

Cache a list of images

Parameters:

skinImgDir - the skinImgDir

baseImageURLs - a list of base urls

cacheImg

public static void cacheImg(java.lang.String skinImgDir,
                            java.lang.String baseImageURL)

Cache a list of images

Parameters:

skinImgDir - the skinImgDir

baseImageURL - the base urls

cacheImgStates

public static void cacheImgStates(java.lang.String skinImgDir,
                                  java.lang.String baseImageURL,
                                  java.lang.String states)

Caches a set of state images derived from a base image. This is useful for caching a set of images for a single component. For example this code:
FileLoader.cacheImgStates("TreeGrid/opener.png","closed,opening,opened");

Will cause the following images to be cached:

/isomorphic/skins/[skin]/images/TreeGrid/opener_closed.png /isomorphic/skins/[skin]/images/TreeGrid/opener_opening.png /isomorphic/skins/[skin]/images/TreeGrid/opener_opened.png

Parameters:

skinImgDir - the skinImgDir

baseImageURL - the base image path

states - a list of states to load.

                                  java.lang.String[] states)

Caches a set of state images derived from a base image. This is useful for caching a set of images for a single component. For example this code:
FileLoader.cacheImgStates("TreeGrid/opener.png","closed,opening,opened");

Will cause the following images to be cached:

/isomorphic/skins/[skin]/images/TreeGrid/opener_closed.png /isomorphic/skins/[skin]/images/TreeGrid/opener_opening.png /isomorphic/skins/[skin]/images/TreeGrid/opener_opened.png

Parameters:
