-
- 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;

- 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.
