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-----

Tix HList missing at least one method
by Ron Provost Aug. 31, 2007

Aug. 31, 2007

According to the Tix documentation online, HList has an info_bbox() method which returns the bounding box of a given item in the HList. However, when I try to call this method, I get an attribute error. Looking at Tix.py I see that info_bbox() is not implemented. Hazarding a chance (mostly by looking at the other method implementation) I see if I can define it myself. def info_bbox( self, entry ): return [ int(pos) for pos in self.tk.call( self._w, 'info', 'bbox', entry).split() ] When I use this implementation it works. Why's info_bbox() been left out of HList? I can't formulate a work-around for what I'm trying to do. I need info_bbox(). Here's why: I'm currently working on a project which involves some fairly complex GUIs. It displays data in the form of an outline which the user can edit, it also generates web pages. To allow a natural feel to editing the order of the items in the outline, I decided to make use of the Tkinter drag and drop module: Tkdnd. To do this correctly, I need to do a bit of arithmetic with screen coordinates while in a drag operation (so I can change the cursor during the drag) so that I can determine if my current drag position (potential drop position) is above, below or as a child of some other item in the outline. The easiest way to do this is to get the bounding box of the nearest items. Thanks, Ron

resize notification
by Titus von der Malsburg Aug. 30, 2007

Aug. 30, 2007

I have a canvas and have to perform some action when it is resized. How can I get notified when resizing happened? How do I find out the amount of the change (without keeping the old size myself)? I tried overriding config (configure), but it is not called during resizing. Thanks for any advice! Titus

sqlite3 operational error with tkinter
by tuxfood Aug. 30, 2007

Aug. 30, 2007

Hi. I am writing a small questionnaire application. I am using sqlite3 and tkinter + python. I started off by writing a console application. The application queries a db file i created . But while using in the gui application i am getting an error that a column cannot be decoded into UTF-8. Is this a problem with the DB file? or has this got to do something with tkinter? I am attaching the source code too. thanks tuxfood http://www.nabble.com/file/p12381457/gui.py gui.py -- View this message in context: http://www.nabble.com/sqlite3-operational-error-with-tkinter-tf4345961.html… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

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.

Aug. 25, 2007

When I run the code below, the data is the second entry box is invisible because the Entry widget is disabled. How can I see the data, but keep the disabled attribute? from Tix import * root = Tk() frame = Frame(root) labent1 = LabelEntry(frame, label="A", labelside = 'left', options = ''' entry.width 40 ''') labent1.entry['background'] = 'gray90' labent1.entry.insert('end', "AAA") labent1['state'] = 'normal' labent1.grid(column=0, sticky=E) labent2 = LabelEntry(frame, label="B", labelside = 'left', disabledforeground = 'red', options = 'entry.width 40') labent2.entry['background'] = 'gray90' labent2['state'] = 'disabled' labent2.entry.insert('end', "BBB") labent2.grid(column=0, sticky=E) frame.grid() frame.mainloop() -- View this message in context: http://www.nabble.com/TkInter-LabelEntry-tf4321384.html#a12306089 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.

In first two cases there is no error message but radiobutton doesn't get disabled... In the third case I got Python error saying DISABLED is not defined. Is there any known issue/problem with disabling Radiobutton widget? thanks a lot --------------------------------- Everyone is raving about the all-new Yahoo! Mail beta.
