setWindowTitleFormat.diff

   1 From: Tony Balinski <ajbj@free.fr>
   2 Subject: Allow a macro to set the document's window title or title format
   3
   4 This is done by allowing the document window to carry a custom version
   5 of the title format string. The new macro function,
   6 set_window_title_format(), is called as follows:
   7
   8         set_window_title_format(string)
   9         set_window_title_format(string, "text")
  10         set_window_title_format(string, "format")
  11
  12 The string will be interpreted as a title format if the "format" keyword is
  13 supplied, or as a fixed title string otherwise. The format directives are
  14 those used in Preferences> Default Settings> Customize Window Title...
  15 dialog. If an empty string is used, the default format (from the
  16 Preferences) is applied.
