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

Centering grid inside a frame
by Vasilis Vlachoudis June 25, 2015

June 25, 2015

Hi all, I want to centre a grid layout (with fixed size) inside a frame e.g. if I do the following tk = Tk() Button(tk, text="button1").grid(row=0, column=0, sticky=NSEW) Button(tk, text="button2").grid(row=0, column=1, sticky=NSEW) Button(tk, text="button3").grid(row=1, column=0, sticky=NSEW) Button(tk, text="button4").grid(row=1, column=1, sticky=NSEW) tk.mainloop() on python 2.7 I get the 4 buttons anchored on the NW corner of the tk frame If I resize the window the buttons are stuck there. I know that I could add an additional frame and use the place manager like f = Frame(tk) f.place(relx=0.5, rely=0.5, anchor=CENTER) and change all buttons to belong to f. However on python 2.4 I get the 4 buttons perfectly centred in the tk frame without the additional f-frame. Is there a special flag that I could do the centering without the need of the extra frame. Thanks in advance Vasilis

You shouldn't do that. Try the following: cd ~ sudo rm -rf .idlerc cd Desktop /usr/local/bin/idle2.7 and see if that works. You should never have to run idle undo sudo and you never should! -- Ned Deily nad(a)acm.org -- []

From the attached screenshots, the IDLE that you have launched is the one included with the OS X system Python (2.7.6), not the latest from python.org and that explains why you get the "8.5.9 in use" warning. I suspect you didn't enter the full path as I suggested above; in the shell window, type the full path "/usr/local/bin/idle2.7" not just "idle2.7". That should ensure that the correct IDLE launches and then, if it still fails, you can see why. You could then also try launching a new terminal window and see whether just typing "idle2.7" gives you the newer version; if not, you may need to adjust your shell startup scripts. The Python installer should have done that by default. -- Ned Deily nad(a)acm.org -- []

Third-party ttk themes
by memilanuk June 17, 2015

June 17, 2015

So... using Anaconda 2.2.0 / Python 3.4.3 on Linux, and the only ttk themes that came with are 'clam', 'alt', 'default' and 'classic'. I've seen reference to other theme names like 'aqua', 'step', 'winnative', 'vista' and 'xpnative'. Are these themes - or others like them - available somewhere, some sort of theme repository? Thanks, Monte -- Shiny! Let's be bad guys. Reach me @ memilanuk (at) gmail dot com

IDLE can't be opened
by Petr Tvrdik June 16, 2015

June 16, 2015

Hello, I have installed Python IDLE from https://www.python.org/downloads/ When I launch the IDLE program I get the error message “The application IDLE can’t be opened.” However, the application WORKS IN ANOTHER ACOUNT on the same machine (Macbook Pro, mid 2010, updated to Yosemite 10.10.3) I have also installed the latest ActiveTcl (buildno 298892) (which is the one recommended for the OS [ActiveTcl8.5.18.0.298892-macosx10.5-i386-x86_64-threaded.dmg] What can I do to make this work? Possible interference with another tkinter? From this or the other login account? Thank you for your input! Best wishes, Petr Tvrdik
