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.

TclError when destroying parent windows
by Jusa June 29, 2008

June 29, 2008

Hi, I've been browsing the tkinter documentation and I just can't seem to figure out how to fix this problem. The problem is that I get one of the following: TclError: bad window path name ".33475080.32213232" or TclError: can't invoke "toplevel" command: application has been destroyed when I destroy a parent window while child windows are being created. All of the windows are subclassed from Toplevel, and I basically have a method which creates a child window on a parent using the parent as the "master" option, and it sounds like I should check whether the parent has been destroyed before creating the child windows. However, I have no idea how I might go about doing this. Any help will be appreciated! -- View this message in context: http://www.nabble.com/TclError-when-destroying-parent-windows-tp18178579p18… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

tkSnack
by Chris Maddison June 18, 2008

June 18, 2008

Greetings, I'm new to the list. I'm a second year comp sci student putting together a small simple media library in Python for first year computer science students. I'd like to do sound, and as far as I can tell tkSnack is one of the simplest ways of doing that. Yet, with the lastest version I get the following error (I'm running this on Mac OS 10.5.3): >>> import tkSnack >>> from Tkinter import * >>> root = Tk() >>> tkSnack.initializeSnack(root) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/tkSnack.py", line 21, in initializeSnack Tkroot.tk.call('eval', 'package require snack') _tkinter.TclError: couldn't load file "/Library/Tcl/snack2.2/ libsnack.dylib": dlopen(/Library/Tcl/snack2.2/libsnack.dylib, 10): no suitable image found. Did find: /Library/Tcl/snack2.2/libsnack.dylib: mach-o, but wrong architecture Has anyone seen this? Any known fixes? Thanks! Christopher Maddison

New member howdy And is there a better way to use Buttons ?
by John Edens June 16, 2008

June 16, 2008

Hi all, I've just started working with Python and Tkinter. One of the things I think I've noted is that Button commands do not pass parameters. Is there a way around this? And is there a better way to code the following: I've written a small application that puts a Label in row 0 of a Frame and puts 26 buttons labeled A - Z in the second row. When the user clicks on a button, the associated letter is displayed in the label. Code follows: # Creates a label in row 0 # Creates 26 buttons A - Z in row 2 # Clicking a button changes the displayed label from Tkinter import * class Application(Frame): def __init__(self,master=None): Frame.__init__(self, master) self.grid() self.tv = StringVar() self.tv.set("?") self.lText = Label(master, textvariable = self.tv) self.lText.grid(row = 0, columnspan = 26) butA = Button(master, text= 'A', command = self.choseA).grid(row = 2, column = 0 ) butB = Button(master, text= 'B', command = self.choseB).grid(row = 2, column = 1 ) butC = Button(master, text= 'C', command = self.choseC).grid(row = 2, column = 2 ) butD = Button(master, text= 'D', command = self.choseD).grid(row = 2, column = 3 ) butE = Button(master, text= 'E', command = self.choseE).grid(row = 2, column = 4 ) butF = Button(master, text= 'F', command = self.choseF).grid(row = 2, column = 5 ) butG = Button(master, text= 'G', command = self.choseG).grid(row = 2, column = 6 ) butH = Button(master, text= 'H', command = self.choseH).grid(row = 2, column = 7 ) butI = Button(master, text= 'I', command = self.choseI).grid(row = 2, column = 8 ) butJ = Button(master, text= 'J', command = self.choseJ).grid(row = 2, column = 9 ) butK = Button(master, text= 'K', command = self.choseK).grid(row = 2, column = 10 ) butL = Button(master, text= 'L', command = self.choseL).grid(row = 2, column = 11 ) butM = Button(master, text= 'M', command = self.choseM).grid(row = 2, column = 12 ) butN = Button(master, text= 'N', command = self.choseN).grid(row = 2, column = 13 ) butO = Button(master, text= 'O', command = self.choseO).grid(row = 2, column = 14 ) butP = Button(master, text= 'P', command = self.choseP).grid(row = 2, column = 15 ) butQ = Button(master, text= 'Q', command = self.choseQ).grid(row = 2, column = 16 ) butR = Button(master, text= 'R', command = self.choseR).grid(row = 2, column = 17 ) butS = Button(master, text= 'S', command = self.choseS).grid(row = 2, column = 18 ) butT = Button(master, text= 'T', command = self.choseT).grid(row = 2, column = 19 ) butU = Button(master, text= 'U', command = self.choseU).grid(row = 2, column = 20 ) butV = Button(master, text= 'V', command = self.choseV).grid(row = 2, column = 21 ) butW = Button(master, text= 'W', command = self.choseW).grid(row = 2, column = 22 ) butX = Button(master, text= 'X', command = self.choseX).grid(row = 2, column = 23 ) butY = Button(master, text= 'Y', command = self.choseY).grid(row = 2, column = 24 ) butZ = Button(master, text= 'Z', command = self.choseZ).grid(row = 2, column = 25 ) def choseA(self): self.resolveChoice( 65 ) def choseB(self): self.resolveChoice( 66 ) def choseC(self): self.resolveChoice( 67 ) def choseD(self): self.resolveChoice( 68 ) def choseE(self): self.resolveChoice( 69 ) def choseF(self): self.resolveChoice( 70 ) def choseG(self): self.resolveChoice( 71 ) def choseH(self): self.resolveChoice( 72 ) def choseI(self): self.resolveChoice( 73 ) def choseJ(self): self.resolveChoice( 74 ) def choseK(self): self.resolveChoice( 75 ) def choseL(self): self.resolveChoice( 76 ) def choseM(self): self.resolveChoice( 77 ) def choseN(self): self.resolveChoice( 78 ) def choseO(self): self.resolveChoice( 79 ) def choseP(self): self.resolveChoice( 80 ) def choseQ(self): self.resolveChoice( 81 ) def choseR(self): self.resolveChoice( 82 ) def choseS(self): self.resolveChoice( 83 ) def choseT(self): self.resolveChoice( 84 ) def choseU(self): self.resolveChoice( 85 ) def choseV(self): self.resolveChoice( 86 ) def choseW(self): self.resolveChoice( 87 ) def choseX(self): self.resolveChoice( 88 ) def choseY(self): self.resolveChoice( 89 ) def choseZ(self): self.resolveChoice( 90 ) def resolveChoice(self,asciiVal): self.tv.set(chr(asciiVal)) root = Tk() app = Application(root) root.mainloop()

displaying images with Label()
by Alexnb June 13, 2008

June 13, 2008

I have looked online for examples and documentation but can't find anything. Not to say that there isn't but I can't find it. Anyway I am wondering how you display images using the Label() function. I tried something like this but it didn't work Label(parent, image="/path/path/image.png") can someone show me an example or point me in the right direction? I would really appreciate it. -- View this message in context: http://www.nabble.com/displaying-images-with-Label%28%29-tp17831398p1783139… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

June 12, 2008

Okay, so in the small app I am creating I want to have a button that activates a file explorer and then once the user selects a file I want to be able to get the path of that file. Is there a way to do this without going into serious detail? and if not could someone point me in the right direction? I am open to about anything.

how to hit enter and get the Entry() text
by Alexnb June 10, 2008

June 10, 2008

Okay, so I am new to Tkinter, and can't figure out how to get the text out of my Entry() text box. I know I can make a button or something like that where they click it and I get it. But what I want to do is have the user typing in the box, and then they hit "return" or "enter" and that also gets it for example: [code] e = Entry(root, width=25) e.pack() Button1 = Button(root, command=get) Button1.pack() def get(): print e.get() [/code] Something like that, only I want to eliminate the button, and make it to where the user hits enter in the text box and it does the get() function.

[ANN] Ttk wrapper 0.0.9
by Guilherme Polo June 8, 2008

June 8, 2008

Hello, Over the last weeks I've been doing a ttk wrapper as part of my GSoC project and now I feel that I can announce it in hope some people start using it. What is Ttk ? This wrapper provides classes to allow using the Tk themed widget set, which has been included in Tk 8.5 but can be used with earlier versions if you have Tile installed. Ttk is based on a revised and enhanced version of TIP #48 (http://tip.tcl.tk/48) specified style engine. Its basic idea is to separate, to the extent possible, the code implementing a widget's behavior from the code implementing its appearance. Widget class bindings are primarily responsible for maintaining the widget state and invoking callbacks, all aspects of the widgets appearance lies at Themes. Wrapper status I expect all the Ttk functionality to be available through this wrapper, but I have said this some days ago as well and found out some examples which failed to work and then I corrected the code. I guess I will only be 100% sure of this after people start using it and reporting problems, if there is some interest on this I can create a project at code.google.com to serve this purpose. The wrapper comes with some samples and documentation too, which can be improved a lot too, specially if people fail to use the wrapper, try to use the docs and fail again and then report how they failed. Getting it Right now you have to use svn to download the wrapper: svn co http://svn.python.org/projects/sandbox/trunk/ttk-gsoc Alternatively, for Python 2.x you can download this file (access the link and click on download): http://svn.python.org/view/sandbox/trunk/ttk-gsoc/Lib/lib-tk/Ttk.py?rev=632… Also, there is a site with some info regarding this project at: http://gpolo.ath.cx:81/projects/ttk_to_tkinter/ Regards, -- -- Guilherme H. Polo Goncalves
