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

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.

Per-state option sintax in TkTreectrl
by Dmitry Gerasimov Aug. 6, 2007

Aug. 6, 2007

Hello! I'm trying to release example from tktreectrl named biglist.tcl using wraper TkTreectrl. There are some lines in tcl source like $T style layout $S eRectTop.e -detach yes -indent no -iexpand xy -draw {yes open no {}} containing per-state values like "{yes open no {}}" for options. How them can be specified for wraper? Writing something like tree.style_layout("styItem","eRectTop", detach="yes", indent="no" , iexpand="xy", draw = "{yes open no {}}") gives unhandled TclError "expected boolean value but got "yes open no {} " on the run.

Workaround for submenus not displaying in 8.4.15
by Russell E. Owen July 25, 2007

July 25, 2007

Under Tcl/Tk 8.4.15 (at least on MacOS X) submenus of menubutton menus don't display (submenus do work fine from the menu bar). This is tk bug 1731734. Anyway, this is causing grief for my application and I was wondering if anyone had found a workaround (other than reverting to an older Tcl/Tk, which I really don't want to do -- this is the first universal binary of Tcl/Tk that reliably keeps track of mouse position; in fact it's the *only* version of Aqua Tcl/Tk other than 8.4.11 that does this). I suppose I could rewrite my application to never use menubuttons with submenus, but I was hoping to not have to change the existing user interface. -- Russell

Dialog and mainloop (UNCLASSIFIED)
by Hensley, Jeffrey L ERDC-ITL-MS Contractor July 15, 2007

July 15, 2007

Classification: UNCLASSIFIED Caveats: NONE I have an application in the works but seem to have a basic misunderstanding of the implementation of standard dialog windows. When the user presses a button to commit an action, I wish to pop up a dialog with a "Are you sure?" query. I'm trying to use the basic askyesno. If the user chooses to continue, we go on our merry way and processing occurs (potentially very time consuming). HOWEVER, even though the user has pressed "yes" or "no", the dialog window itself does not disappear until I fall out of the function and, I believe, the process has returned to the mainloop. The behavior I have now is, well, unacceptable. The underlying processing may take some time, there are messages being written to a status window, etc; and the user is stuck looking at the dialog not aware of what is going on. Am I missing something? [well, of course I am!] Suggestions/comments? ************************************************************** Jeff Hensley, Ph.D. Phone: 601-634-4596 EQM On-site lead, ERDC PET Fax: 601-634-2324 3909 Halls Ferry Road Jeffrey.L.Hensley(a)erdc.usace.army.mil Vicksburg, MS 39180-6199 http://www.erdc.hpc.mil ************************************************************** Classification: UNCLASSIFIED Caveats: NONE
