This module provides access to Macintosh FSSpec handling, the Alias
|
1995-02-28 11:46:09 -04:00
|
|
|
Manager, finder aliases and the Standard File package.
|
|
|
|
|
|
|
|
Whenever a function or method expects a \var{file} argument, this
|
1995-03-13 06:03:32 -04:00
|
|
|
argument can be one of three things:\ (1) a full or partial Macintosh
|
1998-03-17 02:33:25 -04:00
|
|
|
pathname, (2) an FSSpec object or (3) a 3-tuple \code{(\var{wdRefNum},
|
|
|
|
\var{parID}, \var{name})} as described in \emph{Inside Macintosh
|
|
|
|
VI}\@. A description of aliases and the standard file package can also
|
|
|
|
be found there.

|
1995-03-17 12:07:09 -04:00
|
|
|
FSSpec as a string. This is mainly useful if you have obtained an

FSSpec structure over a network.

\begin{funcdesc}{ResolveAliasFile}{file}
|
1995-03-13 06:03:32 -04:00
|
|
|
Resolve an alias file. Returns a 3-tuple \code{(\var{fsspec}, \var{isfolder},
|
|
|
|
\var{aliased})} where \var{fsspec} is the resulting FSSpec object,
|
1995-02-28 11:46:09 -04:00
|
|
|
\var{isfolder} is true if \var{fsspec} points to a folder and
|
|
|
|
\var{aliased} is true if the file was an alias in the first place
|
|
|
|
(otherwise the FSSpec object for the file itself is returned).

|
|
|
Present the user with a standard ``open input file''
|
1995-02-28 11:46:09 -04:00
|
|
|
dialog. Optionally, you can pass up to four 4-char file types to limit
|
|
|
|
the files the user can choose from. The function returns an FSSpec
|
|
|
|
object and a flag indicating that the user completed the dialog
|
|
|
|
without cancelling.

\begin{funcdesc}{StandardPutFile}{prompt, \optional{default}}
|
1995-02-28 11:46:09 -04:00
|
|
|
Present the user with a standard ``open output file''
|
|
|
|
dialog. \var{prompt} is the prompt string, and the optional
|
1995-03-13 06:03:32 -04:00
|
|
|
\var{default} argument initializes the output file name. The function
|
1995-02-28 11:46:09 -04:00
|
|
|
returns an FSSpec object and a flag indicating that the user completed
|
|
|
|
the dialog without cancelling.

\begin{funcdesc}{GetDirectory}{\optional{prompt}}
|
1995-02-28 11:46:09 -04:00
|
|
|
Present the user with a non-standard ``select a directory''
|
1995-08-14 10:39:16 -03:00
|
|
|
dialog. \var{prompt} is the prompt string, and the optional.
|
|
|
|
Return an FSSpec object and a success-indicator.
|
1995-02-28 11:46:09 -04:00

\begin{funcdesc}{SetFolder}{\optional{fsspec}}
|
|
|
|
Set the folder that is initially presented to the user when one of
|
|
|
|
the file selection dialogs is presented. \var{Fsspec} should point to
|
|
|
|
a file in the folder, not the folder itself (the file need not exist,
|
|
|
|
though). If no argument is passed the folder will be set to the
|
|
|
|
current directory, i.e. what \code{os.getcwd()} returns.
|
|
|
|
|
|
|
|
Note that starting with system 7.5 the user can change Standard File
|
|
|
|
behaviour with the ``general controls'' controlpanel, thereby making
|
|
|
|
this call inoperative.

|
Locates one of the ``special'' folders that MacOS knows about, such as
|
1995-10-10 11:43:20 -03:00
|
|
|
the trash or the Preferences folder. \var{Where} is the disk to
|
|
|
|
search, \var{which} is the 4-char string specifying which folder to
|
|
|
|
locate. Setting \var{create} causes the folder to be created if it
|
|
|
|
does not exist. Returns a \code{(vrefnum, dirid)} tuple.

\begin{funcdesc}{NewAliasMinimalFromFullPath}{pathname}
|
|
|
|
Return a minimal alias record object that points to the given file, which
|
|
|
|
must be specified as a full pathname. This is the only way to create an
|

|
alias record pointing to a non-existing file.
|
|
|
|
|
1995-10-10 11:43:20 -03:00
