Inserting a unicode zero-width nonbreaking space into a Text widget, from Tkinter, on a Mac
by Kenneth McDonald Nov. 3, 2004

Nov. 3, 2004

As the subject says, I am attempting to insert a particular unicode character (\ufeff) into a Text widget, from Python. This is not quite working correctly, and I'm not sure if the problem is between Python and Tcl, or is a problem of OS X not properly knowing the character. This character is supposed to be a 0-width space, and using Python's unicodedata.name function confirms that feff is in fact the proper unicode sequence. The character is construction using a one-character python string: zws = u"\ufeff" And then passed to Text's insert command. Unfortunately, what shows up on screen is a complex (perhaps Chinese) asian ideograph. "Python in a Nutshell" indicates that all communication between Tkinter and Tk is in unicode, so I had hoped this would transfer correctly. Not sure if I need to do some conversion or not...could there be a conflict between a straight Unicode (16-bit) representation and a UTF-8 representation? Or do I need to do an OS setting to make sure the OS and the internal representation are on the same wavelength? Thanks, Ken

Printer Dialog
by Faulconer, Steven M. July 27, 2004

July 27, 2004

Hello everyone. I've been searching the net for a printer dialog, preferably written in Tkinter. Haven't been able to find anything as yet, so I thought I'd ask if anyone has seen something like that? I'm looking for something simple that would provide a list of available printers, then print to the one that is selected. Target OS is Windows, though Solaris support would be nice. If anyone has seen something like that, please let me know. Thanks.

The question actually got answered on the tutor list. Please accept my apologies for not updating this list. Thank you for the concern. The end result was the error I received is correct. What I eventually did was pass the instance of my parent class (self) in addition to the parent root instance. This allowed me to make a function calls on my parent class instance. I'll post my final code for comments when it is completed. Thanks for the concern.

My impression is that it's MUCH easier than he's making it, but I'm not in a po- sition to address it any time soon. I sure don't want him thinking that we're unresponsive or that Tkinter is difficult, both of which I know to be false, with occasional exceptions. 'Anyone comfortable with PMW have time for this?

Tkinter Class / Data passing
by Faulconer, Steven M. July 23, 2004

July 23, 2004

Hello everyone, I have a program I've written that essentially acts as a graphical front-end to several in-house written command-line programs. The script is using Tkinter/Pmw as the interface language. The software works like this: A user runs the script and is presented with an interface where they select a 'project' and a 'database'. The user clicks a button to accept those selections, which starts a new window. In this window is a number of Pmw group widgets containing a set of widgets for each command-line program (we call them 'checkers'). Each checker widget group has a button to run the checker software (command-line). This is redirected to a NEW Toplevel window. My question is, what is the best method for getting data out of this new Toplevel window? Meaning, this new Toplevel window has a set of buttons that allow the user to accept the software run, based on the output, or cancel the run (not accepting the run). The issue is, how do I tell the parent the outcome? I've tried creating a variable in the parent and setting it in various places in the child, but that doesn't seem to work. The value never changes. I've even tried using a global variable, but that still doesn't work. I debated attaching the code, but I think it will help with my issue. MainApp is the primary window that runs first. It starts a new CheckerApp window, which lists all the checkers, and starts a CheckerWindow when the user actually clicks the 'run checker' button in the checkerapp. How can I tell the CheckerApp, from within CheckerWindow, what button the user selected (accept/deny). I'm sure its obvious by my code, but I'm a new programmer, and the script is still unfinished. Constructive criticism is greatly appreciated. And please let me know if I did not explain the issue well enough. Thanks. Steven

RE: [Tkinter-discuss] Changing the fonts on my Pmw.NoteBook tabs
by Peter Milliken July 20, 2004

July 20, 2004

The following is under the "Dynamic Components" section of the reference page for Pmw.NoteBook: "Page and tab components are created dynamically by the add() and insert() methods. By default, the pages are of type Tkinter.Frame and are created with a component group of Page and the tabs are of type Tkinter.Button and are created with a component group of Tab." Using this information as a "clue" :-), you can use calls to get the components of the NoteBook i.e. assuming your notebook instance was called "DisplayPages" and it had tabbed pages called "Entry", "Results" then you would have the following print self.component("DisplayPages").components() ['Entry', 'Entry-tab', 'Results', 'Results-tab', 'hull'] So the Frame component for the Entry tabbed page is called 'Entry' and the Button that contains the name (and font you want to manipulate) is called 'Entry-tab'. So to change the font is something like this: self.component('DisplayPages').component('Entry-tab').configure(font = ('Helvetica', 10, 'bold italic')) This is probably more detail than you were asking for but hey, what the hell! :-) Regards Peter -----Original Message----- From: Netherdog(a)cs.com [mailto:Netherdog@cs.com] Sent: Tuesday, July 20, 2004 2:57 PM To: tkinter-discuss(a)python.org Cc: clnethery(a)juno.com Subject: [Tkinter-discuss] Changing the fonts on my Pmw.NoteBook tabs Hello everyone.

Problem trying to use Tkinter in non-gui script
by Parimala Ramdas July 9, 2004

July 9, 2004

Hello all! I have a piece of gui code using Tkinter that I put in a file viewcvs.py of ViewCVS software. What I'm trying to do is, display a dialog box when user clicks on a link "Download" The purpose is to ask for a username before allowing user to download files. As soon as username is entered in dialog box, it will verify the name. The code works stand-alone but gives me error in viewcvs.py file. Anyone has any idea why? Thanks in advance. Parimala Code: sys.path.append('/usr/lib/python1.5/lib-tk/') import Tkinter root = Tkinter.Tk() Tkinter.Label(text="Welcome") root.mainloop() Python Exception Occured Traceback (innermost last): File "/usr/local/viewcvs-0.9.2/lib/viewcvs.py", line 2741, in run_cgi main() File "/usr/local/viewcvs-0.9.2/lib/viewcvs.py", line 2722, in main download_tarball(request) File "/usr/local/viewcvs-0.9.2/lib/viewcvs.py", line 2624, in download_tarball root = Tkinter.Tk() File "/usr/lib/python1.5/site-packages/lib-tk/Tkinter.py", line 886, in __init__ self.tk = _tkinter.create(screenName, baseName, className) TclError: no display name and no $DISPLAY environment variable Even if I copy lib-tk in site-packages dir, it gives me the same error.
