	Popstring class is the base class for creating so called
	popup objects. Usually, a popup consists of a string or
	text gadget, followed by a little button. Pressing this
	button brings up a little window with a listview and lets
	the user choose an entry with the mouse.

	Popstring class features the basic functions for creating
	such objects. Given a string object and a button object,
	it places them horizontally and sets up some notification.
	Whenever the popup button is pressed, a hook will be called 
	which itself should open and prepare the popup window.

	The string and the button object are not created by popstring
	class, they have to be supplied as attributes during object
	creation time. This makes popstring class very flexible,
	one could e.g. use a text object instead of a string or
	a popup button with some text in it.

	However, creating simple popups with popstring class would
	be too much overhead. Instead of using it directly, you
	should have a look at one of its subclasses. They offer
	a more specialized set of popups and are a lot easier
	to use.
Popstring.mui/MUIM_Popstring_Close

    NAME
	MUIM_Popstring_Close (V7 )

    SYNOPSIS
	DoMethod(obj,MUIM_Popstring_Close,LONG result);

    FUNCTION
	This method closes the popup. In fact, it only calls the
	predefined MUIA_Popstring_CloseHook with the supplied
	success parameter.

    EXAMPLE
	DoMethod(poplist,MUIM_Notify,MUIA_Listview_DoubeClick,TRUE,
	   popobj,2,MUIM_Popstring_Close,TRUE);
Popstring.mui/MUIM_Popstring_Open

    NAME
	MUIM_Popstring_Open (V7 )

    SYNOPSIS
	DoMethod(obj,MUIM_Popstring_Open,);

    FUNCTION
	This method opens the popup. In fact, it only calls the
	predefined MUIA_Popstring_OpenHook and checks its return
	value. In case of TRUE, the popup button object is disabled
	as long as MUIA_Popstring_Toggle is unset.

	If the toggle mode is enabled, using MUIA_Popstring_Open on
	a currently opened popup will result in closing this popup
	(i.e. calling the close hook) with a success value of FALSE.

    EXAMPLE
	DoMethod(popbutton,MUIM_Notify,MUIA_Pressed,FALSE,
	   popobj,1,MUIM_Popstring_Open);
Popstring.mui/MUIA_Popstring_Button

    NAME
	MUIA_Popstring_Button -- (V7 ) [I.G], Object *

    FUNCTION
	Specify the button object to be used in the popup. Depending
	on the type of your popup, you should use an image button
	with MUII_PopUp, MUII_PopFile or MUII_PopDrawer here.
	However, its also possible to have a button with some
	text or other things in it.

	When the popstring object is disposed, the string
	and the button objects are disposed as well.

    EXAMPLE
	pop = PopstringObject,
	   MUIA_Popstring_String, KeyString(0,60,'n'),
	   MUIA_Popstring_Button, PopButton(MUII_PopUp),
	   MUIA_Popstring_OpenHook, &OpenHook,
	   MUIA_Popstring_CloseHook, &CloseHook,
	   End;

    SEE ALSO
	MUIA_Popstring_String, MUIA_Popstring_OpenHook, MUIA_Popstring_CloseHook
Popstring.mui/MUIA_Popstring_CloseHook

    NAME
	MUIA_Popstring_CloseHook -- (V7 ) [ISG], struct Hook *

    FUNCTION
	Whenever the popup receives a MUIM_Popstring_Close method and
	the popup is currently opened, this hook will be called. 
	It will receive a pointer to itself in register A0, a pointer
	to the complete popup object in A2 and a pointer to a
	struct
	{
	   Object *stringobject;
	   LONG success;
	},
	in A1. The success parameter is a copy of the methods success
	parameter and indicates whether the popup was closed successfully
	(e.g. with a double click in a listview) or was just cancelled
	(e.g. by pressing the popup button again for toggle popups).

	Due to internal message handling issues, calling the close hook is
	delayed until the next MUIM_HandleInput method is called. This
	allows you to remove and dispose windows without danger.

Popstring.mui/MUIA_Popstring_OpenHook

    NAME
	MUIA_Popstring_OpenHook -- (V7 ) [ISG], struct Hook *

    FUNCTION
	Whenever the popup receives a MUIM_Popstring_Open method,
	this hook will be called. It will receive a pointer to itself in
	register A0, a pointer to the complete popup object in A2 and
	a pointer to a pointer (!) to the string object contained in
	the popup object in A1.

	When this hook returns TRUE, MUI assumes the popup was opened
	succesfully and will disabled the popup button (as long as
	MUIA_Popstring_Toggle is not set). Return FALSE to indicate
	that something went wrong and the popup could not be opened.

Popstring.mui/MUIA_Popstring_String

    NAME
	MUIA_Popstring_String -- (V7 ) [I.G], Object *

    FUNCTION
	Specify the string object to be used in the popup.
	This does not necessarily need to be a real string
	object, using text objects or even complete groups
	of other objects is perfectly ok.

	When the popstring object is disposed, the string
	and the button objects are disposed as well.

    EXAMPLE
	pop = PopstringObject,
	   MUIA_Popstring_String, KeyString(0,60,'n'),
	   MUIA_Popstring_Button, PopButton(MUII_PopUp),
	   MUIA_Popstring_OpenHook, &OpenHook,
	   MUIA_Popstring_CloseHook, &CloseHook,
	   End;

	MUIA_Popstring_Button, MUIA_Popstring_OpenHook, MUIA_Popstring_CloseHook
Popstring.mui/MUIA_Popstring_Toggle

    NAME
	MUIA_Popstring_Toggle -- (V7 ) [ISG], BOOL

    FUNCTION
	Set/Clear the toggle mode for a popstring object.
	With toggling disabled, the popup button will get
	disabled whenever the user hits it and the popup
	opens. With toggling enabled, the popup button
	always stays enabled and can be used to cancel
	(== close with a FALSE return value) the popup.
