Possibly n00bish question about ImageTk
by Barnesdesdes Feb. 10, 2009

Feb. 10, 2009

I've been trying to make a program which will import a png file and display it inside a frame. It actually works when I just run the code, but if I try to abstract the exact same code into a function, it fails. In the code below, if I just run it, it works. However, if I comment out the lines between "root=Tkinter.Tk()" and "moo(root)" and comment in "moo(root)", it no longer works. Instead of displaying the image, it just displays a gray frame of the correct size. Does anyone have any insights about what I'm doing wrong? import Image, ImageTk, Tkinter def moo(master): img = Image.open('plotfig.png') f = Tkinter.Frame(master, width=800, height=600) pi = ImageTk.PhotoImage(img) t = Tkinter.Label(f, image=pi) f.pack() t.place(x=0, y=0, width=800, height=600) t.pack() root = Tkinter.Tk() img = Image.open('plotfig.png') f = Tkinter.Frame(root, width=800, height=600) pi = ImageTk.PhotoImage(img) t = Tkinter.Label(f, image=pi) f.pack() t.place(x=0, y=0, width=800, height=600) t.pack() #moo(root) root.mainloop() Thanks very much.

Shareware product using Tkinter
by Kevin Walzer Jan. 7, 2008

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I know there is a lot of talk about Tkinter being an antiquated toolkit, unsuitable for commercial software development. However, I am using Tkinter in one of my shareware programs: http://www.codebykevin.com/packetstream.html (there's a screenshot) This application makes use of some recent advances in Tk development, including Tile (see http://tkinter.unpythonic.net/wiki/TileWrapper for the Python wrapper). It also makes use of some nice Tkinter widgets such as ToolTip (http://tkinter.unpythonic.net/wiki/ToolTip). If you pay attention to some of the specifics of the platform you are targeting (this app is for Mac OS X users) and to other points of application design, such as icons (I find the Tango set to be very polished and well-suited for the Mac; it doesn't scream "Linux"), then I think it's quite possible to make a nice, polished, professional-looking application with Tkinter. I'm curious if anyone has thought about gathering a listing of other Tkinter applications, commercial or otherwise, that are well-designed/attractive. Perhaps a screenshot page at the Tkinter wiki or elsewhere? - -- Kevin Walzer Code by Kevin http://www.codebykevin.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD4DBQFFntpOEsLm8HXyq4sRAuxMAJQOpHKZf9dGrxO/0F0UVIPMr8vZAJsGIHT9 pYgEgO+j2Q83GocIWWOzqA== =7aqI -----END PGP SIGNATURE-----

self modifying buttons - memory game
by RickB Aug. 29, 2007

Aug. 29, 2007

I assume there is probably a better way to do this. The code is functional but its really slow if you have a large amount of buttons. http://www.nabble.com/file/8220/gui.py gui.py -- View this message in context: http://www.nabble.com/self-modifying-buttons---memory-game-tf3693914.html#a… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

Hiya G G In case you're a freak about namespace polution (and that's really a good thing), you can generally rest assured that you'll be almost always fine when you do a full namespace import of Tkinter module.

Re: [Tkinter-discuss] Possibly n00bish question about ImageTk

Hi Alan, in your function 'moo' 'pi' is a local variable which gets garbage collected when the function returns. Thus your image goes to gc nirvana. Making 'pi' global like this def moo(master): global pi img = Image.open('plotfig.png') f = Tkinter.Frame(master, width=800, height=600) pi = ImageTk.PhotoImage(img) t = Tkinter.Label(f, image=pi) f.pack() t.place(x=0, y=0, width=800, height=600) t.pack() should do the trick. This is a guess as I am not using Image and ImageTk. But I had the same problem with Tix.PhotoImage. So I guess this is it. BTW you use 'place' and 'pack' for the label. As I understood your supposed to use exactly ONE geometry handler for a gui element in tk. Hope this helps, Matthias Kievernagel (mkiever/at/web/dot/de)

different results from the same tcl script
by Fabrizio Pollastri June 25, 2007

June 25, 2007

Hello, in mixed python-tcl programming I found the following different behaviours of the same tcl script. If I type manually in the python interpreter the following lines >>> from Tkinter import * >>> w = Tk() >>> w.tk.evalfile('my_tcl_script.tcl') where my_tcl_script.tcl is #!/bin/sh package require Tk wm withdraw . toplevel .root wm title .root "My title" I obtain one toplevel window with title "My title", as expected. The same result is obtained with the tcl shell command % wish my_tcl_script.tcl Now, I wish to run the same instructions from a python script. So, I written the following script from time import * from Tkinter import * w = Tk() w.tk.evalfile('my_tcl_script.tcl') sleep(3) The result of this python script is nothing, no window appears. If anybody can explain the different behaviour and how to normalize it with the correct one, I will be very glad. Thank you in advance. F. Pollastri

single button threading
by Brill IanT June 19, 2007

June 19, 2007

I am writing an application which fetches and parses a large number of urls for hyperlinks. My problem is that when the prog is in the middle of the 'fetching' stage, the gui becomes almost completely unresponsive. This is not at all what I want. I want the user to be able to interact with the gui while this process is going on. Even if just one button, a 'stop' button, is the only thing working, I would be satisfied with that. Is there a way to perhaps thread a button or two while urllib2 is busy fetching a big list of urls? I ask this with some trepidation because I know how thread unfriendly tkinter is. If there is no solution to this, can anyone tell me if reconstructing the gui with wx would help with this matter? I don't want to do this because I am familiar with tk and find it far easier to work with, but I really have to find a way of solving this problem. Thank you very much for reading, and I hope someone can help me out. --------------------------------- Yahoo! Answers - Get better answers from someone who knows. Tryit now.

Ugly fonts with tkinter
by January Weiner June 15, 2007

June 15, 2007

I am sure this has been asked a hundred times, but I could not find an answer in Google. I have recently started programming using Tkinter and python. Before, I was heavily using Perl-Tk, so I have some experience with that kit. My system is Ubuntu 7.04. My problem are the extremly ugly bitmap fonts used by Tkinter. Here is an example: http://hell.pl/january/python_fonts_example.png I remember having a similar problem in perl-tk, and having for that two solutions: 1) choose a different font (optionAdd method of the main window with e.g. Arial 10) 2) recompiling perl-tk with an antialias option set, so that one gets fully anti-aliased fonts. First, I would like to use option (1), but I don't know enough of tkinter to find it. Furthermore, I would like to know what is the status on (2). Is tkinter using somehow its own tk libraries, or does it relies on system wide libraries? Do you have any experience with using antialiased fonts with tkinter?

visualtcl as ui designer for tkinter
by Fabrizio Pollastri June 8, 2007

June 8, 2007

Hello, I am trying to use VisualTcl as an interface designer. The tcl file produced by VisualTcl is executed in my application as root = Tk() root.tk.evalfile('my_tcl_gui.tcl') I have found two problems. First, the toplevel "root" supersede the toplevel options defined in the tcl file (typically the window title). Second, the tcl file evaluation stops for "argc" undefined. Similar tcl files created with TkproE do not suffer this problems. Thank for any help. Regards, F. Pollastri
