  :Contents.    Die Makros die in "mui.h" definiert waren als Prozeduren
  :Imports.     <Importiertes, Name/ShortCut des Autors>
  :Remarks.     Bei VCenter, HCenter, Popup ist es etwas anders.
  :Bugs.        <Bekannte Fehler>
  :Usage.       <Angaben zur Anwendung>
  :History.     .1     [awn] 22-Aug-1993 : Die Prozeduren die in Mui.mod waren nun
  :History.            entfernt und ein seperates Modul daraus gemacht, so das
  :History.            man nicht darauf angewiesen dies in seinem Interfaces zu haben.
  :History.     .2     [awn] 24-Aug-1993 : Kräftig aufgeräumt um den erzeugten
  :History.            Maschinencode so kurz wie möglich zu halten.
  :History.     .3     [awn] 24-Aug-1993 : PopupEnd() so erweitert das nun ein
  :History.            Objekt mit angeben werden kann, dies ist dafür gedacht wenn
  :History.            man das Popup zu einem anderen Objekt anordnet (z.B String )
  :History.     .4     [awn] 24-Aug-1993 : Im Zuge der Popup Änderung wurde eine
  :History.            eigene Speziell auf Mui abgestimmte Hook Parameter übergabe
  :History.            erstellt (Allerdings OS Konform eingebettet). Der Parameter
  :History.            Deklaration der Hook-Prozedur muss nun so aussehen wie der
  :History.            Typ `HookDef'.
  :History.     .5     [awn] 25-Aug-1993 : Tipfehler bei TagItem2() und TagItem3()
  :History.            entfernt.
  :History.     .6     [awn] 25-Aug-1993 : Die Groups und Frames wieder mit der
  :History.            Möglichkeit versehen dort TagListen zu übergeben.
  :History.     .7     [awn] 30-Aug-1993 : PageGroup() hizugefügt.
  :History.     .8     [awn] 14-Sep-1993 : Fehler bei Strings() dort wurde in der
  :History.            Deklaration 2 mal A1 benutzt.
  :History.     .9     [awn] 03-Oct-1993 : Eine einfache Plausibiltätsprüfung eingebaut.
  :History.            Für jede #?Object() Prozedur gibt es nun ein End#?() Prozedure,
  :History.            wenn der Objekt Typ nicht übereinstimmt wird ein NIL zurückgeben.
  :History.            Dies ist dafür um während der Programmentwicklung Abstürze zu
  :History.            umgehen, wenn das Programm einmal steht sind diese nicht mehr
  :History.            notwendig, aber brauchen nicht entfernt zu werden.
  :History.     .10    [awn] 30-Oct-1993 : An MUI 1.4 angepasst, die neuen Objekte
  :History.            hinzugefügt (Coloradjust, Colorfield, Palette, Virtgroup, Scrollgroup
  :History.            und Scrmodelist), die Group Prozeduren gibt es nun auch für Virtgroups
  :History.            z.B. HGroupV(). Sonstige neue Prozeduren, KeyRadio(), Slider(), KeySlider(),
  :History.            LLabel?() und KeyLLabel?().
  :History.     .11    [awn] 31-Jan-1994 : Angepasst an MUI 1.5, Fehler bei SliderObject()
  :History.            entfernt (Rief RadioObject auf). Es gibt nun für *jede* Objekt ein
  :History.            passendes. Bei Popupend() wird nun auch das Background Image gesetzt.
  :History.     .12    [awn] 02-Feb-1994 : INewObject() und IEnd() aufgenommen, der Aufruf
  :History.            von INewObject() ist wie der von Intuition.NewObject() nur ohne
  :History.            Rückgabeparamter. INewObject() muss *anstatt* Intuition.NewObject()
  :History.            aufgerufen werden wenn die Objekte direkt mit ins Layout sollen.
  :History.            INewObject() *muss* ein IEnd() bzw. iEnd() folgen. siehe Class1.mod
  :History.     .13    [awn] 05-Feb-1994 : VSlider() und KeyVSlider() aufgenommen.

** Object Generation
** -----------------
**
** The xxxObject (and xChilds) procedures generate new instances of MUI classes.
** Every xxxObject can be followed by tagitems specifying initial create
** time attributes for the new object and must be terminated with the
** End macro:
**
** StringObject;
**          TagItem2( Mui.aStringContents, "foo",
**                    Mui.aStringMaxLen  , 40 );
** obj := End();
**
** With the Child, SubWindow and WindowContents shortcuts you can
** construct a complete GUI within one command:
**
** ApplicationObject;
**
**          ...
**
**          SubWindow; WindowObject;
**             WindowContents; VGroup;

** Labeling Objects

**   Small: |foo   |
**  Normal: |bar   |
**     Big: |foobar|
**    Huge: |barfoo|
**

** ColGroup(2);

**    Child; StringObject; end;
**      Child; Label2( "Normal:" );

**    Child; StringObject; end;
**      Child; Label2( "Huge:"   );
**    Child; StringObject; end;
**    end;
**
** Note that we have three versions of the label procedure, depending on
** the frame type of the right hand object:
**
** Label1(): For use with standard frames (e.g. checkmarks).
** Label2(): For use with double high frames (e.g. string gadgets).
** Label() : For use with objects without a frame.
**
** These procedures ensure that your label will look fine even if the
** user of your application configured some strange spacing values.
** If you want to use your own labeling, you'll have to pay attention
** on this topic yourself.
