CountDITL

You can determine the number of items in a dialog box by using the CountDITL function.

FUNCTION CountDITL (theDialog: DialogPtr): Integer;

theDialog

A pointer to a dialog record.

DESCRIPTION

The CountDITL function returns the number of current items in a dialog box. You typically use CountDITL in conjunction with ShortenDITL to remove items from a dialog box.

SPECIAL CONSIDERATIONS

The CountDITL function is available in System 7 and in earlier versions of the Communications Toolbox. Before calling CountDITL, you should make sure that it is available by using the Gestalt function with the gestaltDITLExtAttr selector. Test the bit
indicated by the gestaltDITLExtPresent constant in the response parameter. If the bit is set, then CountDITL is available.

SEE ALSO

The Gestalt function is described in the chapter "Gestalt Manager" in Inside Macintosh: Operating System Utilities.
