Control position of Tkinter common dialogs?
by python＠bdurham.com Dec. 9, 2016

Dec. 9, 2016

Python 2.7 under Windows: How can we control the position of Tkinter's common dialogs? Here's what we've discovered: * Certain common dialogs always open up relative to their parent window * Certain common dialogs always open up centered on the user's desktop * All common dialogs appear to ignore the optional parent= parameter Questions: * How can we force a dialog to open up relative to its parent window? * How can we force a dialog to open up centered on the user's desktop? Background: import tkColorChooser as colorchooser import tkFileDialog as filedialog import tkMessageBox as messagebox # always open up relative to parent windows fileOpen = filedialog.askopenfilename() fileOpens = filedialog.askopenfilenames() fileSaveAs = filedialog.asksaveasfilename() color = colorchooser.askcolor() # always open up centered on desktop folderOpen = filedialog.askdirectory() messagebox.askquestion() Malcolm

Macosx Tk colors changed
by Michael O'Donnell May 29, 2013

May 29, 2013

Dear all, My application manages the window appearance by building a frame with gifs, and filling with a background color that should be identical to that of the gifs. This has been fine under all versions of Python up to and including 3.3.2. But under 3.3.2 on MACOSX, Idle recommended I upgrade to Tk 8.5.14 (previously I had 8.5.9), so I upgraded from ActiveState. Now, the background color is a shade or two lighter than the gifs, making my interface look clunky. When I move back to Windows, where the Python installer for 3.3.2 includes Tk 8.5.11, I have no problem. So I am not sure if it is Tk version after 11, or if it is a later version but just on the Mac. Does anyone know anything about changes to Tk colour rendering that might explain this. A test case is below (Python 3), with the required GIF file in attachment. If all is fine, the canvas presents a uniform gray. If there is a small lighter gray square in the middle, then you have duplicated the problem. import tkinter root = tkinter.Tk() print("TK Version: ", root.getvar("tk_patchLevel")) c=tkinter.Canvas(root, bg="#bbc0c6", height=100, width=100) c.pack(side='left') button=tkinter.PhotoImage(file="left.gif") c.create_image(50, 50, anchor="nw", image=button) root.mainloop() Any help welcome, Mick

I'm going to reply to the three messages in this one post. @Kevin: Thank you very much, Kevin! I had good memories with BWidgets on Tk about 10 years ago (wow). Hope it now has even more to offer with tkinter. I'm also curious about the performance and stability of the extensions. Would they perform well with basic widgets together? @John: I'm interested in some specialized widgets I saw in other toolkits, such as the "rating" widget (NSLevelIndicator) in Cocoa. @Alejandro: It sounds like a good idea to have an RAD tool for designing widgets. I gave it a quick look. Does it support only python 3.2+(?) or is it just that it requires py3.2 to run the toolkit itself but it can also generate py2 stuff?

tkinter extensions
by Beinan Li May 18, 2013

May 18, 2013

Hi Tkinter, I'm new to the list and have to confess that I'm a newbie that needs recommendations on high-level (compound) widgets based on tkinter. As far as I understand, I assume ttk has quite a number of high-level widgets such as notebook, but the inventory is still not as big as one may find in other toolkits like wx or qt. >From tkinter website (http://wiki.python.org/moin/TkInter), I saw a list of extensions: - Pmw <http://wiki.python.org/moin/Pmw> (http://pmw.sourceforge.net) - Tix <http://wiki.python.org/moin/Tix> ( http://www.python.org/doc/current/lib/module-Tix.html) - TkZinc <http://wiki.python.org/moin/TkZinc> (http://www.tkzinc.org) - Tkinter3000 <http://wiki.python.org/moin/Tkinter3000> ( http://tkinter.effbot.org) - How Tkinter can exploit Tcl/Tk extensions<http://wiki.python.org/moin/How%20Tkinter%20can%20exploit%20Tcl/Tk%20extens…> But not sure if that list still up to date. Correct me if I'm wrong please. I followed the links and found that at least Pmw, TkZink (last update 2007, http://www.tkzinc.org/news/) and Tkinter3000 (last update in 2006: http://effbot.org/zone/wck.htm) are not under active dev. Tix looks like already part of the stdlib, but this page ( http://stackoverflow.com/questions/12499465/tix-tutorials-in-python) suggests that ttk can largely replace it. Personally I doubt it because if that were the case, Tix (py2) or tkinter.tix (py3) wouldn't coexist with ttk for this long. But I don't see a lot of tutorials about how to use Tix with tkinter. That stackoverflow post is probably the closest clue I can find. So I wonder if Tix has been widely adopted. Then about using Tcl/Tk extensions directly ( http://wiki.python.org/moin/How%20Tkinter%20can%20exploit%20Tcl/Tk%20extens… ) that seems to be the technique used by tkinter.tix under the hood (?). I wonder, from your experience, if this approach can provide acceptable stability and performance. Please feel free to give other recommendations about compound widgets if any. If you'd say that Tix is my best bet then any docs or resources about it would be welcomed. Thanks, Beinan

Button Press Freezes
by Quaki Gaffar May 18, 2013

May 18, 2013

Here's my situation. I have two tkinter buttons: Play Button: plays a sound Stop Button: to stop the sound during play Code is as follows: def Play(self): //plays a file with pygame module def Stop(self): //Stop using pygame stop Button( root, text ='Play', command= Play).pack() Button( root, text ='Stop', command= Stop).pack() The issue is that, when I click the 'Play' button, it stays pressed until it completes playing the sound, freezing the entire program, not allowing me to press 'stop' button during that time. How do i prevent the program from freezing while the play is in progress to allow me to do other things like stop? i tried a suggestion proposed here, but it does not work. Any ideas would be greatly appreciated :)

Making a MDI GUI using Tkinter
by Chitrank Dixit May 12, 2013

May 12, 2013

Hello Python Developers I am working on an application that should support the Multiple documents in a wrapper called MDI. But I am unable to do that. I want to ask some questions below 1) using a container that suits MDI ( Frame or Canvas or anything else). 2) When button pressed for option1 one then show option1 and when button pressed for option2 show option2 and when again pressed for option1 it should come up as the front window. 3) The following wrapper should also support as an image holder like canvas or can hold the canvas to show the images. *Regards * *Chitrank Dixit * *IIPS-DAVV * *Indore (M.P.) , India * *MCA * *trackleech.blogspot.in*

tkinter gui builder
by Alejandro Autalan April 30, 2013

April 30, 2013

Hello all, I'm working on a simple gui builder for tkinter similar to Glade (the gtk builder). It is Not finished yet and there is little documentation. However, I invite you to try it and comment or make suggestions. There are some examples that you can follow. I named it pygubu, the code is here: https://github.com/alejandroautalan/pygubu As I said, comments and suggestions are welcome, enjoy it. Regards Alejandro A.
