radioOpenPrev.diff

   1 From: Tony Balinski <ajbj@free.fr>
   2 Subject: Display the File->Open Previous menu using radio buttons
   3
   4 The radio buttons indicate which files are currently open.
   5
   6 The rebuilding of the Open Previous menu is also performed when a document
   7 is closed, to allow the refresh of "torn-off" copies of this menu. This is
   8 why the invalidatePrevOpenMenus() function was made public rather than
   9 static.
