Thanks for the pointers. Apologies in advance if this is a silly question, but how do I obtain the bindings to the drscheme:unit:frame<%> interface? Looking around the code, it seems that type is often imported into a tool unit, but I could not find any definition. -pp <div>On 10/4/06, Robby Findler <<a href="mailto:robby@cs.uchicago.edu">robby@cs.uchicago.edu</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I guess you'd want to iterate over all of the frames, via get-top-level-windows. Find those that implement the drscheme:unit:frame<%> interface, and then use the get-tabs method to get the tabs in those frames. From those tabs, use get-defs to get the definitions text and from that use get-filename to get the filename. To actually bring a different file to be editing, use handler:edit-file. (It also works to open new files and open empty windows/tabs if you pass #f).      .... but ... the get-tabs method doesn't exist in the 352 or anywhere else for that matter, until just a minute ago when I added it to the svn version of DrScheme. It's an easy patch, if you'd rather patch your version of drscheme than get the svn version. Just look for get-tabs in the svn sources and copy that one line into your version: <a href="http://svn.plt-scheme.org/plt/trunk/collects/drscheme/private/unit.ss">http://svn.plt-scheme.org/plt/trunk/collects/drscheme/private/unit.ss </a> hth, Robby At Wed, 4 Oct 2006 17:32:57 -0500, "pedro pinto" wrote: > Sorry, that was a rather cryptic post, here is some context: > > <a href="http://list.cs.brown.edu/pipermail/plt-scheme/2006-July/014115.html"> http://list.cs.brown.edu/pipermail/plt-scheme/2006-July/014115.html</a> > -pp > > > On 10/4/06, Robby Findler <<a href="mailto:robby@cs.uchicago.edu">robby@cs.uchicago.edu</a>> wrote: > > > > At Wed, 4 Oct 2006 17:20:01 -0500, "pedro pinto" wrote: > > > Hi there, > > > > > > I posted about this issue some months ago.
