- NAME
- AllocAslRequest -- allocate an ASL requester. (V36)
- AllocAslRequestTags -- varargs stub for AllocAslRequest(). (V36)
-
- SYNOPSIS
- requester = AllocAslRequest(reqType,tagList);
- D0 D0 A0
-
- APTR AllocAslRequest(ULONG,struct TagItem *);
-
- requester = AllocAslRequestTags(reqType,firstTag, ...);
-
- APTR AllocAslRequestTags(ULONG,Tag,...);
-
- FUNCTION
- Allocates an ASL requester data structure of the specified type.
-
- INPUTS
- type - type of requester to allocate. Currently defined types
- are ASL_FileRequest, ASL_FontRequest and ASL_ScreenModeRequest.
- ASL_ScreenModeRequest is available starting with asl.library
- V38 only.
- tags - pointer to an optional tag list specifying how to initialize the
- data structure returned by this function. See the
- documentation for AslRequest() for an explanation of
- how to use the currently defined tags.
-
- RESULT
- requester - an initialized requester data structure, or NULL on
- failure. The data structure returned corresponds to the
- requested type;
- ASL_FileRequest -> (struct FileRequester *)

- ASL_ScreenModeRequest -> (struct ScreenModeRequester *)
-
- WARNING
- All ASL requester data structures are READ-ONLY and can only be

- NAME
- AslRequest -- get input from user using an ASL requester. (V36)
- AslRequestTags -- varargs stub for AslRequest(). (V36)
-
- SYNOPSIS
- result = AslRequest(requester,tags);
- D0 A0 A1
-
- BOOL AslRequest(APTR,struct TagItem *);
-
- result = AslRequestTags(requester,firstTag,...);

-
- FUNCTION
- Prompts the user for input, based on the specific type of
- requester and modifying tags. The actions and results
- are specific to the type of requester, but in general the action is
- to open a requesting window prompting the user for a specific input.
- If the user cancels or the system aborts the request, FALSE
- is returned, otherwise the requester's data structure reflects the
- user input.
-
- Note that tag values stay in effect for each use of the
- requester until they are cleared or modified by passing the
- same tag with a new value.
-
- INPUTS
- requester - requester structure allocated with AllocAslRequest(). If
- this parameter is NULL, this function will always return
- FALSE with a dos.library/IoErr() result of
- ERROR_NO_FREE_STORE.
- tags - pointer to an optional tag list which may be used to
- control features of the requester.
-
- TAGS
- Tags for use with the file requester:
-
- ASLFR_Window (struct Window *) - Parent window of requester. If no
- ASLFR_Screen tag is specified, the window structure
- is used to determine on which screen to open the
- requesting window. (V36)
-
- ASLFR_PubScreenName (STRPTR) - Name of a public screen to open on.
- This overrides the screen used by ASLFR_Window. (V38)
-
- ASLFR_Screen (struct Screen *) - Screen on which to open the requester.
- This overrides the screen used by ASLFR_Window or by
- ASLFR_PubScreenName. (V38)
-
- ASLFR_PrivateIDCMP (BOOL) - When set to TRUE, this tells ASL to
- allocate a new IDCMP port for the requesting window.
- If not specified or set to FALSE, and if ASLFR_Window
- is provided, the requesting window will share
- ASLFR_Window's IDCMP port. (V38)
-
- ASLFR_IntuiMsgFunc (struct Hook *) - A function to call whenever an
- unknown Intuition message arrives at the message port
- being used by the requesting window. The function
- receives the following parameters:
- A0 - (struct Hook *)
- A1 - (struct IntuiMessage *)
- A2 - (struct FileRequester *)
- (V38)
-
- ASLFR_SleepWindow (BOOL) - When set to TRUE, this tag will cause the
- window specified by ASLFR_Window to be "put to
- sleep". That is, a busy pointer will be displayed in
- the parent window, and no gadget or menu activity will
- be allowed. This is done by opening an invisible
- Intuition Requester in the parent window. (V38)
-
- ASLFR_UserData (APTR) - A 32-bit value that is simply copied in the
- fr_UserData field of the requester structure. (V38)
-
- ASLFR_TextAttr (struct TextAttr *) - Font to be used for the requesting
- window's gadgets and menus. If this tag is not provided
- or its value is NULL, the default font of the screen
- on which the requesting window opens will be used.
- This font must already be in memory as ASL calls
- OpenFont() and not OpenDiskFont(). As of V38, the font
- used in the file requester's file list must be
- monospaced. If the font provided with this tag is
- not monospaced, then the file list will use the current
- system default font as chosen in preferences. (V38)
-
- ASLFR_Locale (struct Locale *) - Locale to use for the requesting
- window. This determines the language used for the
- requester's gadgets and menus. If this tag is not
- provided or its value is NULL, the system's current
- default locale will be used. As of V38, items such as
- the date format always uses the system default locale.
- (V38)
-
- ASLFR_TitleText (STRPTR) - Title to use for the requesting window.
- Default is no title. (V36)

- string could not be longer than 6 characters. (V36)
-
- ASLFR_NegativeText (STRPTR) - Label of the negative gadget in the
- requester. English default is "Cancel". Prior to V38,
- this string could not be longer than 6 characters.

-
- ULONG function(ULONG mask, APTR object,
- struct FileRequester *fr)

- The Mask value is a copy of the specific ASLFR_Flags1
- value the callback is for, either FRF_FILTERFUNC or

- RESULT
- result - FALSE if the user cancelled the requester or if something
- prevented the requester from opening. If TRUE, values in the
- requester structure will be set depending on the particular
- type of requester.
-
- Under V38, If the return value is FALSE, you can look
- at the result from the dos.library/IoErr() function to
- determine whether the requester was cancelled or simply
- failed to open. If dos.library/IoErr() returns 0, then the
- requester was cancelled, any other value indicates a failure
- to open. Current possible failure codes are
- ERROR_NO_FREE_STORE which indicates there was not enough
- memory, and ERROR_NO_MORE_ENTRIES which indicates no modes
- were available for display in the screen mode requester
- (usually because the application filter hook filtered them
- all away)
-
- WARNING
- All ASL requester data structures are READ-ONLY and can only be
- modified by using tags!
