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-----

Tkinter on MacOS 10.3.9
by Michael O'Donnell Oct. 16, 2007

Oct. 16, 2007

Dear all, I made a standalone application using py2app on a Mac running OS 10.4.9, using Python 2.51, using Tkinter. It works fine on Macs of the 10.4.x vintage. However, a user in China reports the following crash on startup: ImportError: dlcompat: dyld: /Users/bernadetteho/Desktop/UAMCorpusTool.app/Contents/MacOS/UAMCorpusTool can't open library: /Library/Frameworks/Tk.framework/Versions/8.4/Tk (No such file or directory, errno = 2) and the Corpus Tool had to be terminated. Anyone know how to solve this problem? I don't have access to OS 10.3.9, so cannot check it out. Could I just zip up the contents of my own /System/Library/Frameworks/Tk.framework/ and send that to her to install? Would that work? I tried deleting my Tcl and Tk frameworks on my own system and then installing TclTkAqua-8.4.10 from the following url, and then trying my own application, but it reported incompatible builds: http://prdownloads.sourceforge.net/tcltkaqua/TclTkAqua-8.4.10.dmg?download Mick

widget focus switching problems.
by Nicholas Oct. 15, 2007

Oct. 15, 2007

I'm having difficulty switching focus between widgets in my program. This is a mostly non-functioning GUI to be used for database creation, saving and retreival. The code currently looks horrifyingly unPythonic since I'm very new to this and I'm just kind of hacking my way through it. It's also several hundred more lines than I should put in here. My major question is if there is a Python or Tkinter piece of code that will excecute itself as though I had pressed the tab button? In other words, I'd like to bind the return key, when pressed in my Entry box, to switch focus (or Tab) to the next item in the focus loop. I have the focus turned off for all other widgets aside from the ones created by the function below and one button (the one that will save the entries to the db). Sorry if this is long-winded, but I'm not sure what I'm talking about enough to be concise. Anyway, here's the code so far and what I think it does: ########################## variables = [] # clears previously collected values for field in SHORTKEYS: # iterates over a list of 40 items ent = Entry(rite) # creates the entry box ent.pack(side = TOP, fill = X) # packs the entry box if field == 'name': # 'name' is the first entry box, ent.focus_set() # so it gets focus on startup ent.bind('<Return>', return_pressed) # binds <Return> on all entry boxes var = StringVar() # ent.config(textvariable=var) # all the other lines convert the entries variables.append(var) # to a list I can use later. return variables # ########################## Any help would be greatly appreciated. Thanks, Nick

Re: [Tkinter-discuss] Unicode in MacOSX: any progress?
by Michael O'Donnell Oct. 10, 2007

Thanks Matthias, I had checked out the tcl/tk8.5 sources, and saw that the font rendering on Macs does indeed use the ATSU code. However, I fear to try to integrate tcl/tk8.5 with Tkinter, and will wait for Tkinter itself to switch to tcl/tk8.5 (hopefully next year?) The ATSU patch itself: I cannot find it - all links it it seem to lead to dead pages. Anyone know a url from which i can download it?

Hello Michael, in my answer back in october 2006 to Mike Gasser on this list, I referred to a thread I found here: http://aspn.activestate.com/ASPN/Mail/Message/tcl-mac/2865240 This thread discusses a patch for tk 8.4.9 to enable support for something called "Apple Type Services for Unicode Imaging" (ATSUI). Being also somewhat interested I looked into the ChangeLogs of the current releases of tk. From the info found there I guess that this patch has never been incorporated in the 8.4 branch (No mention of it in the current 8.4.16 release). But it is mentioned in the current 8.5 Beta release. This looks like you have to move to 8.5 for unicode on MacOSX (and see what other things in Tkinter break :-) or find the patch and do it yourself for 8.4. BTW Mike Gasser never reported success/failure to the list. I would be very interested to hear if and how it works for you. Matthias Kievernagel mkiever-at-web-dot-de

Unicode in MacOSX: any progress?
by Michael O'Donnell Oct. 9, 2007

Oct. 9, 2007

Dear all, I develop an application for linguistic annotation, using python/tkinter, and have just extended my code to support unicode text files. All went fine on the Windows version (where I develop), but when I took my code over to MacOS (Tiger, with python 2.5.1), I find Tkinter cannot display unicode under MacOS. A previous posting (mikegasser at sbcglobal.net) almost a year ago gave a simple example: #========================= from Tkinter import * import tkFont root = Tk() myFont = tkFont.Font(size=18) w = Label(root, text=u'Bun\u0103-diminea\u021ba, lume', font=myFont) w.pack() root.mainloop() #========================= This works fine under Windows, but displays squares for the unicode chars under MacOSX. This has not been fixed in the last year. Are there any solutions to this problem? Mick
