This example exhibits: * iterate over available fonts using font.get_fonts and font.SysFont() * click and drag using mouse input * scrolling with the scroll wheel * save a surface to disk * work with a very large surface * simple mouse and keyboard scroll speed acceleration By default this example uses the fonts returned by pygame.font.get_fonts() and opens them using pygame.font.SysFont(). Alternatively, you may pass a path to the command line. The TTF files found in that directory will be used instead. Mouse Controls: * Use the mouse wheel or click and drag to scroll Keyboard Controls: * Press up or down to scroll * Press escape to exit éNFc@s^eZdZdZdZdZdd„Zdd„Zdd d „Zd d „Z d d„Z ddd„Z ddd„Z dd„Z dS)Ú FontViewerz— This example is encapsulated by the fontviewer class It initializes the pygame window, handles input, and draws itself to the screen. é é2cCs t ¡tj ¡}|j}|j}tj t|dƒt|dƒf¡|d|_tj   ¡|_ d|_ d|_ | d¡tsJsz,FontViewer.get_font_list..)
