The main interface for this MP3 player and MP3 component features a "dual control" system whereby volume, pan, repeat, and shuffle can be controlled by mouse click either in the control bar or the main viewing panel. The applet version (remember: BOTH the applet version and component versions are included!) features an XML configuration file, which is loaded at run-time. The XML file can be edited using any good text editor, like Textpad or Editplus. 100% of the Flash source code is included! That includes ALL .fla and .as files, and all component files like .mxp and .swc files. The Flash MP3 component is installed into the Flash extension manager, simply by double-clicking the .mxp file. Please note that the component version requires the Flash IDE, and is intended for Flash developers only. The Flash MP3 component is configured through the component properties window after dragging the component to the Flash stage. The applet version only is configured via XML.
