Widget to appear square-shaped on screen...
by GKalman July 22, 2010

July 22, 2010

I'm trying to make a square-shaped board, something like this: from Tkinter import * root = Tk() w=[] for k in range(9): i=k/3 j=k%3 w.append(Label(root,text=str(k),bg="red",width=5,height=5)) w[k].grid(row=i,column=j,padx=2,pady=2,ipadx=5,ipady=5) mainloop() It shows up on my screen as rectangular (non-square) shaped. What do I have to do to make it appear in a square-shaped form (i.e. with Label height & width to be equal on the sceen)? -- View this message in context: http://old.nabble.com/Widget-to-appear-square-shaped-on-screen...-tp2921612… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

Tkinter (IDLE) freeze when I try to use ttk
by Guido Carballo-Guerrero July 12, 2010

July 12, 2010

Hello, I just update my Python version to 2.7. I was doing some programs using Tkinter and ttk. By the way I have a Mac running 10.6.4. Well, after I install Python, I install ActivePython2.6.5--I try to install 2.7.0 but at the end of the installation it gave me an error message--and ActiveTcl, this 'cause I discover that if I didn't do that, Python will use Tcl and Tk 8.4, which doesn't allow me to use ttk. No my problem is that I can't use Python's IDLE. Well, I can only open one window at a time. If I try to open a new window to make a program, Python freeze. Some curios, if that if I don't have Python open, and double click on a program, Python opens the IDLE and the program in to separate windows without a problem, but when I try to run the program it freeze. I guess that this is a bug somewhere in the ttk implementation, or in Python. Do you guys have any idea how can I solve this? Or have anybody update Python to 2.7, and use ttk on a Mac? If so, please let me know how you manage to do it. Regards! Guido

Tkinter (IDLE) freeze when I try to use ttk
by Guido Carballo-Guerrero July 11, 2010

July 11, 2010

Well, I fix the problem. The best to install Python on a Mac is to download the source files and do: $ ./configure --enable-universalsdk --enable-framework $ make $ make frameworkinstall Inside of the folder where you have all the files of the source. Something to remember is that you need to have SDK install in the computer. But after I did this, now I can use Python, Tkinter and ttk without any problems. And I notice that in some of the lines after one type make, Tcl, and Tk frameworks are call. Now if I do: >>> import Tkinter as Tkt >>> Tkt.TclVersion 8.5 As you can see the Tcl version is 8.5, which is what ttk needs to run without problems. Regards!

So if you try to run another tkinter application from IDLE, the two mainloop() calls interfere with each other. You should be able to run console applications from IDLE, but with tkinter applications you can develop them using IDLE but run them from a console (or whatever is used as a console on a Mac). It's nothing to do with the Python version or with ttk and I doubt it can be called a bug. > > HTH > Sibylle > ___________________________________________________________ > WEB.DE DSL ab 19,99 Euro/Monat.

How to capture exceptions after the end of the program
by Vasilis Vlachoudis July 1, 2010

July 1, 2010

Hi all, I have a tkinter application that uses several fonts. However only with python 2.4 when the application is closed then I get the following exceptions (with 2.6 it works Ok) Exception exceptions.AttributeError: "'NoneType' object has no attribute 'TclError'" in <bound method Font.__del__ of <tkFont.Font instance at 0x2ac0dd4c4908>> ignored Exception exceptions.AttributeError: "'NoneType' object has no attribute 'TclError'" in <bound method Font.__del__ of <tkFont.Font instance at 0x2ac0dd4c4680>> ignored and I have no way of capturing them since they arrive even after the last line of the program. I believe that for some reason the tkinter is deleted before and afterwards it tries to delete the fonts and creates the TclError. Is there a way to protect for these exceptions? I was getting the same problem with the PhotoImage() but now I am trying to delete all of them before the end of the program to avoid the exceptions. However with fonts I can miss something e.g replace a font and exit afterwards. Thanks in advance Vasilis -- ------------------------------------------------------- Vasilis Vlachoudis Dep.
