Tkinter on iPad/iPhone?
by Michael O'Donnell April 29, 2010

April 29, 2010

Hi all, I was thinking of porting my python application to an iPad, I see that there is general support for python on these devices via PyObjC. However, no support for Tkinter, that I can see. Anyone know of such support? Mick

Michael, Wayne; I'm sorry, I just found my problem. Was something dumb: L1.config(image = photo1) L1.image = image1_2 This was the problem. I should had: L1.config(image = photo1) L1.image = photo1 Now it's working as expected. Thank you very much any way for your help, really appreciated.

Wayne, Michael; This is a sample code that shows what I'm doing. As you can see, even if I don't have a while loop, the picture is not being shown. Am I missing something? What is wrong with my code that I can't open and show the picture in the new Toplevel window?

Re: [Tkinter-discuss] Returning control from a toplevel
by Guido Carballo-Guerrero April 28, 2010

Michael; What I did to solve the problem, was put the while loop inside of a function, so when I'm exiting the toplevel windows, I call that function, in that way I get back into the while loop. Is there a problem with this? What is the problem of calling the mainloop in the various windows? Why I can't display the pictures unless I call the mainloop inside of the toplevel windows? What happens when I call the mainloop inside of the toplevel windows, that kick me out of the while loop? Cause you're right, when I don't call mainloop inside of the new toplevel window, everything keeps running in the main program as if anything had happen. Regards! Guido

Micheal, but if I don't call the mainloop again inside of the toplevel window the pictures that I'm trying to display doesn't show up.

Returning control from a toplevel window
by Guido Carballo-Guerrero April 28, 2010

April 28, 2010

How can I get back into a while loop if I go to a new pop-up toplevel window, that is created when I press one button. I'm attaching a sample of the code that I'm trying to make. The problem that I have is that after the button is press and the new toplevel window, what ever is inside of the while loop doesn't do anything anymore. Is as if I got out of the while loop. Is there a way in which I can get back into the while loop once the toplevel window is destroy? Guido

problem with menus, Tkinter on macpython
by Joe Barfett April 26, 2010

April 26, 2010

Hello again, The last time I updated, I think my code was scrambled. I am still having the same problem in that I cannot make a menu appear using Tkinter on macpython. The exact same code works very well on my PC. This is the code: from Tkinter import * root = Tk() def hello(): print "hello!" # create a toplevel menu menubar = Menu(root) menubar.add_command(label="Hello!", command=hello) # display the menu root.config(menu=menubar) mainloop() I'm using windows XP and python version 2.5 with Tkinter. A menu appears. The exact same code on OSX 10.5 and 10.5 in macpython will display a frame but no menu. Can anyone help? Thanks very much! joe

Getting a canvas within an existing frame.

I cannot get my canvas to show within my existing frame. I can only get it to build it's own frame. Can someone help? As you can see i've tried a number of different things so i have a lot of stuff commented out at the bottom. attached is a picture of what my GUI looks like.

How can I tell Tkinter where to look for Tcl/Tk?
by Guido Carballo-Guerrero April 23, 2010

April 23, 2010

Hello, I have a Mac, running OS X 10.6.3, and have Python 2.6.4 install. I already install ttk, got it from: http://pypi.python.org/pypi/pyttk But when I try to use ttk, it with me the following error: Traceback (most recent call last): File "/Users/Charras/Documents/CS/Python/programs/Tkinter/ttk/prueba1.py", line 6, in <module> style = ttk.Style() File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/ttk.py", line 392, in __init__ _load_tile(master) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/ttk.py", line 60, in _load_tile master.tk.eval('package require tile') # TclError may be raised here TclError: can't find package tile I read somewhere that this mean that I had an old Tcl/Tk version, and I check it, and yes, that was the case: >>> import Tkinter as Tkt >>> Tkt.TkVersion 8.4000000000000004 So I download and install version 8.5 from activestate.com. Now I have TCL/TK 8.5 install in my machine, inside of "/Library/Frameworks/Tcl.framework/Versions/8.5". and "/Library/Frameworks/Tk.framework/Versions/8.5"., but I guess that if even after doing this, Tkinter still sees 8.4 is 'cause I need to tell it to go and load this new version and read from there, but I don't know how to do that. Can somebody guide me on how to do it? Regards Guido

from where can I download and install ttk?
by Guido Carballo-Guerrero April 22, 2010

April 22, 2010

Hello, I have install in my computer Python 2.6.5, but I just realize that Tkinter for this version don't have ttk install. Does anybody know from where can I download ttk to install it. Apparently Python 3.1 already have ttk inside of Tkinter, is there a reason why I should prefer to use 2.6.5? What are the differences between them (2.6 and 3.1)? Guido
