I'm implementing the TTK wrappers to access Tk 8.5. Implementing a ttk wrapper won't give you this "count" command, since this is a command for an already existing widget (the text widget), it is not part of the ttk widgets. Also, there is already a ttk wrapper at http://pypi.python.org/pypi/pyttk which is being proposed to be included in python's stdlib. > Although when I check the wrapper I don't see any mods to the Text > Box.

Fortunately it is easily done: import Tkinter def text_count(self, index1, index2, *options): args = ["-%s" % opt for opt in options] args.extend([index1, index2]) return self.tk.call(self._w, "count", *args) Tkinter.Text.count = text_count Then to try it: root = Tkinter.Tk() text = Tkinter.Text() text.pack() text.insert("1.0", "a\nb\c\nd") print text.count("1.0", "end", "displaylines", "lines") root.mainloop() Note that I inverted the order of the arguments here, indices and then the options or no options. If it doesn't work saying "count" is not an acceptable command then your tkinter is not compiled against tcl/tk 8.5 or later. > > > On Oct 28, 6:51 pm, "Guilherme Polo" <[EMAIL PROTECTED]> wrote: > > > > > Are you looking for something like the new "count" command for the > > text widget in tk 8.5 ?
