Visual (8-bit!) tkinter Cheatsheets

Hi all, For many reasons, but mainly just for fun, I made some tkinter documentation in pixel graphics. I'd like to share what I made, here it is..! [image: grid_layout.png][image: button.png] It's pretty exhausting work, making letters pixel by pixel, but I like the results (assuming you can even see them.) If I receive encouragement and interesting criticism, I think I'll be motivated to make a few more. {:)}= I think next, I want to document row & column configuration on the Grid, and perhaps how Images work. Please feel free to share these however you like. Take care, Lion (If the images don't go through the mail, here are two URLs to them: http://twitpic.com/2t4n9p/full http://twitpic.com/2t4n9q/full )

Callback when insertion cursor moves
by Baz79 Sept. 30, 2010

Sept. 30, 2010

Hi there, I have two text widgets. I have managed to program these so that they can be scrolled by the same scroll bars. However, if I move the cursor position in one widget, how can I get it to also move in the other widget? Thanks for your help, Barry -- View this message in context: http://old.nabble.com/Callback-when-insertion-cursor-moves-tp29851368p29851… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

Correct order for dialog display
by Vasilis Vlachoudis Sept. 30, 2010

Sept. 30, 2010

Dear all, In my application I have several custom made Toplevel windows when they close they remember their position and size, so the next time to open them using with the same geometry. Therefore in the show method I have the following sequence def show(self): self.deiconify() self.geometry("%dx%d+%d+%d", self.width, self.height, self.x, self.y) self.wait_visibility() In my linux Fedora-13, Ubuntu 10.04 etc.. works Ok. However on Mac, Fedora-13 through a virtual machine (VirtualBox) or over the network the geometry card seems to be ignored. The window appears to be where the window manager likes with size whatever Tk likes If I change the order like self.wait_visibility() self.geometry("...") then it works on all systems, BUT first it displays the window where the window manager likes with the standard size that Tk calculates AND THEN it move&resize to the correct position. On fast machines is not a problem, but on slow machines or X11 over the network it becomes annoying. So my question is: if I want to position and resize a Toplevel window (before it is shown), so when it is displayed to have the dimensions/position that I choose, what is the correct order of commands to use in order to work in all systems? Thanks in advance Vasilis

tkinter module
by Hèlen Grives Sept. 23, 2010

Sept. 23, 2010

Hi, I'm a newbie in programming (2 weeks) and I use a windows vista 32 computer. I've currently installed the phyton - 3.2.a2.msi file. Previciously I used versions 2.7 and 3.0 and 3.1.2. But no one gets the tkinter module to start. All the previous releases are uninstalled. However I don't know how to get around this problem quickly. My goal is to go back to the last 3.1.2 version and get it to work properly. I hope you have any suggestions that are not too difficult without a lot of knowledge.

Hello, I am a total beginner with python and tkinter and I am having a hard time getting my program working, I think the problem come from passing variables. I would like to have a menu that would with three main buttons, the first one (LUT) let me chosse between two files, the second button (rrs) opens a browser to choose a file and the third button would run a program (or function) that makes some computation between the two files open with button 1 and button 2, Here is what I have written from Tkinter import * from tkFileDialog import askopenfilename import numpy as np class openfile(): def __init__(self, yn): if yn == 0 : self.lut = np.loadtxt("C:\python26\LUTnpdi_chile",dtype=np.float,skiprows=1) if yn == 1 : self.lut = np.loadtxt("C:\python26\LUTnpdi_nwa",dtype=np.float,skiprows=1) if yn == 2 : filename = askopenfilename(filetypes=[("allfiles","*"),("pythonfiles","*.py")]) if yn == 2 : self.lut = np.loadtxt(filename,dtype=np.float,skiprows=1) Class rrs_file(self,rrs): filename = askopenfilename(filetypes=[("allfiles","*"),("pythonfiles","*.py")]) rrs = np.loadtxt(filename,dtype=np.float,skiprows=1) def make_comp(): result = self.lut[1,2] * rrs[1,2] print result def callback(): print "called the callback!" root = Tk() # create a menu menu = Menu(root) root.config(menu=menu) filemenu = Menu(menu) menu.add_cascade(label="LUT", menu=filemenu) filemenu.add_command(label="East Pacific", command=lambda:openfile(0)) filemenu.add_command(label="NW Atlantic", command=lambda:openfile(1)) image_menu = Menu(menu) menu.add_cascade(label="Rrs", command=rrs_file) run_menu = Menu(menu) menu.add_cascade(label="Run", command = make_comp) quitmenu = Menu(menu) menu.add_cascade(label="Quit", command=root.destroy) #x = openfile(2) mainloop() I can not figure out how to pass get the lut and rrs parameters that I have defined in the class objects? I need help !!! Thank you very much in advance. Emmanuel

Monte; I don't know that. Maybe somebody from here might be able to answer that, but I don't know. I'm kinda new into Tkinter as well. I have less than a year using it. What I told you was what worked for me. And yes, what worked for me was installing source, which I download from here: http://www.python.org/download/ I don't understand as well, why the Mac Os x Installer Disk Image don't come already with Tk/Tcl 8.5, specially since the Windows installer already comes with all that ready, but well. I would even suggest that Python should come with ttk. Those anybody knows what Python doesn't comes already with ttk? Why the Mac installer doesn't have Tk/Tcl as part of the installation? But anyway Monte, in the mean time, try what I suggest. For me works just fine. As I told you before, if you need detail instructions on how to install Python and ttk from source, let me know.

I'd debated about whether to use MacPython or Activestate Python, which sounded like it supported the newer versions of tk better, but it also sounded like in order for that to work I'd have to download and install Activestate Tcl as well... maybe that's the simplest option...? > > Are you saying that in order to use ttk with MacPython I need to compile python from the source code? > > Is there some particular reason why the folks @ python seem to resist upgrading to tkinter 8.5 & tile/ttk? I thought it had been out for *years* now (well before python 2.6, anyways)... why do I need to jump thru all these dang hoops to use what seems like it should be the current version of things? Sorry for the vent... I realize I'm very new to this and probably lack perspective and all that, but I'd really like to know. > > Thanks, > > Monte > > > > > > _______________________________________________ > Tkinter-discuss mailing list > Tkinter-discuss(a)python.org > http://mail.python.org/mailman/listinfo/tkinter-discuss

Yes Kevin, I know Snow come with Tk/Tcl 8.5, but for some reason if one install Python with the dmg installer from Python/Download installer, for some reason ttk doesn't use Tcl/Tk 8.5, but 8.4 instead. To make Python use 8.5 one have to compile the source code, with the following lines: $ ./configure --enable-universalsdk --enable-framework $ make $ make frameworkinstall Maybe I'm missing something, but that's how is for me.

Tkinter in interactive mode locks when run from subprocess
by 刘文彬 Sept. 1, 2010

Sept. 1, 2010

Hi, In Windows, I made an interactive window by C#, which creates a remote python subprocess to do the interpreting. Communication is done via standard IO redirection. The idea is that the python session is an actual process separate from the GUI, which has some advantages, like I can have multiple such shells in my application, and I can kill them without worrying that my C# app will crash. This all works really, I will also launch C# apps. So I was quite happy, untill I tried doing some plotting with Tkinter. The problem is that the process becomes unresponsive when I do something(more details below) I don't know much about creating subprocess and redirecting standard IO of subprocess and how they are different from a normal process. So can anyone offer some help as to what the problem might be? Thanks in advance, Kaster To get to the details: I use a textbox component of C# to receive the command and then run it as a normal Python console - When I start with command "import Tkinter" -work well,and then command "r = Tkinter.Tk()" problem is arose, a small window pops up, and then whichever command I run in the textbox is not working. I think may be something block the input so that the command cannot transfer to the subprocess of python, but I don't know how to resolve the problem.
