Poppen.mui Background

        Poppen class adds input capabilities to its super class
        Pendisplay. It should be used if your application allows 
        users to configure some custom pens for rendering.

        A Poppen object will appear as kind of a button which 
        displays the currently selected color. When the user hits 
        the button, a Popup window containing a Penadjust object 
        opens up and lets the user choose change the color.

        You can control the window title of the popup window using 
        the MUIA_Window_Title on the Poppen object. It will remember 
        its value and use it when creating the popup window.

        As most MUI popups, the Penadjust popup window runs 
        asynchronously and stays there until the user terminates 
        it with "OK" or "Cancel". Furthermore, if the popup window 
        is automatically cancelled if the pop button receives a 
        MUIM_Cleanup method.

        Anyway, you dont have to care about the internals of this class.
        Just create it like

        obj = MUI_NewObject(MUIC_Poppen,
                MUIA_CycleChain  , 1,
                MUIA_Window_Title, "Followed Links Color",

        somewhere in your prefs window and everything will be fine. You
        can get/set the current color from a Poppen object by using
        the MUIA_Pendisplay_Spec attribute. The resulting struct
        MUI_SpenSpec may then be saved somewhere in your preferences
        and used as parameter for MUI_ObtainPen() and MUI_ReleasePen().

        You can find some example code on using this class in the
        Class2 demo of the MUI distribution.
