Class GifResource

  • public abstract class GifResource
extends java.lang.Object
    Provides a single method only, getIcon(Class), which returns the icon associated with the given class. The class must be a subclass of GifResource as is Open. That class is also an example for using GifResources: Just derive a class from GifResource and put it into a package (org.javalobby.icons16x16 in this case) pointing to the according gif-image which can be found in this case in src/main/resources/org/javalobby/icons16x16/Open.gif.

      • getIcon

        public static javax.swing.ImageIcon getIcon​(java.lang.Class<? extends GifResource> res)
        Converts a GifResource class into the corresponding icon. This is done in the following steps: If the image is cached in GIFS, take this one. Else load it into GIFSas described below before taking it from GIFS.

        Loading an image consists in loading the class-file associated with the image, determining the according gif-file and creating the according ImageIcon.

        Parameters:
        res - a subclass of GifResource.
        Returns:
        the icon determined by the given class.

        CAUTION: Note that an icon is returned even if there is no according gif-image. This image can be identified by width -1 which is an undocumented property.
