- * @defgroup Thumb Thumb
- *
- * A thumb object is used for displaying the thumbnail of an image or video.
- * You must have compiled Elementary with Ethumb_Client support and the DBus
- * service must be present and auto-activated in order to have thumbnails to
- * be generated.
- *
- * Signals that you can add callbacks for are:
- *
- * "clicked" - This is called when a user has clicked the thumb without dragging
- * around.
- * "clicked,double" - This is called when a user has double-clicked the thumb.
- * "press" - This is called when a user has pressed down the thumb.
- * "generate,start" - The thumbnail generation started.
- * "generate,stop" - The generation process stopped.
- * "generate,error" - The generation failed.
- * "load,error" - The thumbnail image loading failed.
