SavePanel   statement / function

Statement syntax
savepanel tag, msg, fileTypes, nameFldString, prompt, dirURL, sheetFlag

Function syntax
url = savepanel tag, msg, fileTypes, nameFldString, prompt, dirURL

Use this statement/function to:
  • Create a new savepanel dialog;
  • Run an existing savepanel;
  • Alter an existing savepanel's characteristics.

  • Parameters
    tag A number (1 through 1000000) that you assign when you create the savepanel and that you refer to when altering the panel. A negative value builds the panel invisibly and doesn't run it until the statement is executed with a positive value.
    Note: Once the panel has been dismissed, its tag value is no longer valid.
    msg The message text displayed in the save panel.
    fileTypes A semicolon-delimited string or an array of strings specifying the allowed file types for the panel. The value of this property specifies the file types the user can save the file as. A file type can be a common file extension, or a UTI. The default value of this property is nil, which indicates that any file type can be used.
    Note: old four character OSTypes are not supported.
    nameFldString The user-editable filename currently shown in the name field.
    prompt The prompt of the default button.
    dirURL The URL of the initial directory shown when the panel is displayed.
    sheetFlag A boolean value to indicate if the panel will be a sheet attached to the current output window.
    Note A sheet panel does not return a value from the savepanel statement, but instead posts an _savePanelDidEnd event to the user on dialog function.
    Return value (non-sheet dialog only)
    The URL of the saved file. Returns NULL if the dialog was cancelled.
    Ancillary functions
    The following optional functions enhance the savepanel and should be called while the panel is invisible (before running the panel).
    1. Using savepanel to specify a filename does not actually save the file. Use the open statement if you need to save the file.
    2. A returned CFURLRef should not be saved to refer to a file/directory at a later date (i.e. across machine restarts). If you need to keep track of a file's location over time, create and save an alias or bookmark for the file.
    3. The returned CFURLRef object will need to be retained if not used immediately.
