Hey Adam,          
   List boxes do have settable fonts. So do most all PM controls now in 1.2
Using WinSetPresParams() you can tell a control to set his colors as well
as his font.

for example

HWND   hControl;
ULONG  color;
CHAR   font[20];

   hControl =WinWindowFromID( hwnd, LB_ITEMS);
   /* Assuming a window with a listbox with an ID of LB_ITEMS */
   strcpy( font, "12.Courier");
   WinSetPresParams( hC, PP_FONTNAMESIZE, sizeof( font), font);

   This is a cheap way to get the columns of a listbox to line up, but hey.
   
   color =CLR_YELLOW;
   WinSetPresParams( hC, PP_FOREGROUNDCOLORINDEX, sizeof( ULONG), &color);
   color =CLR_BLUE;  
   WinSetPresParams( hC, PP_BACKGROUNDCOLORINDEX, sizeof( ULONG), &color);

   This will change the listbox to do all its output in yellow on blue.
   Pretty useful. But remember, the user changed his system colors with the
   control panel. We should use these APIs with a clear head and proper
   judgement else we fall prey to congression regulators regulating our 
   user-interface code.
