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

ttk.Notebook - how to bind to tab events (tab caption has focus or mouseover)
by python＠bdurham.com May 9, 2012

May 9, 2012

I'm using the ttk.Notebook widget. What object do I bind to capture events related to specific tabs? I would like to trap when a tab caption gets keyboard focus ('<FocusIn>') and when the mouse pointer is over a specific tab caption ('<Enter>'). I can trap mouse clicks on tabs (<Button-1>, <Button-3>), but I can't find a way to determine what tab a user clicked on in the case of a right click. Thank you, Malcolm

Button command callback question -- Part 2
by GKalman July 19, 2011

July 19, 2011

Thanks for the replies for my earlier question. I should have stated my question in a better way. My question is related to SCOPE! For example: #==================================== from Tkinter import * #------------------------------------------------- def doIt(): print x #------------------------------------------------ root=Tk() btn=Button(root,text="DO",bg="cyan",command=doIt) btn.pack(side=BOTTOM) x=11 #NOTE that it works even when the mainloop() method below is commented out!!!! #root.mainloop() #=================================================================== so: if (1) there is no mainloop() (2) x=11 is declared in the MAIN part (3) command=doIt() has no argument (4) doIt() fn appears ahead of the x=11 statement My Question is: why x=11 is within the scope of the doIt() callback fn? -- View this message in context: http://old.nabble.com/Button-command-callback-question----Part-2-tp32082790… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

A Button command callback question...

The following code fragment works OK. Question: why? #====================================== from Tkinter import * root=Tk() lbl=Label(root,text='1').pack() def doIt(): lbl.config(bg="yellow") btn=Button(root,text="do", bg="cyan",command=doIt).pack() root.mainloop() #======================================= My question is: how is the instance lbl.config(...) recognized in the doIt callback fn when called from the main w/o an argument referencing lbl? -- View this message in context: http://old.nabble.com/A-Button-command-callback-question...-tp32080551p3208… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

Re: [Tkinter-discuss] tkFileDialog.askdirectory() not resizable in Windows
by Lynn Oliver July 18, 2011

t turns out that the problem was an outdated version of init.tcl that was (still?) present after installing ActivePython 2.7.2.5. After replacing that file with the one from the 8.5.9 source it is now working properly.

tkFileDialog.askdirectory() not resizable in Windows
by Lynn Oliver July 16, 2011

July 16, 2011

Using Python versions 2.6.6 or 2.7.1, the tkFileDialog.askdirectory() dialog box is resizable in OS X but not on WinXP or Win7. tkFileDialog.askopenfilename() is resizable in both environments. Is there a way to work around this? Lynn

Re: [Tkinter-discuss] Tkinter-discuss Digest, Vol 89, Issue 5

George; I haven't install python 3.1, and as far as I knew, 3.1 was a little bit different than 2.7 with respect to ttk, or maybe is python 3.2. By the way, why you're installing 3.1 instead of 3.2? You know, 3.2 is the latest version, maybe installing this version is easier, but any way, this is what I did to make 2.7 work with ttk: 1. download the source code and not the installer package 2. uncompress the file--the computer does this automatically for you 3. go where the package was uncompress using the terminal--oper a terminal, and type: ls ~/Downloads/python..., instead of the points write the name of the folder that was created when you uncompress the file you download 4. type the following commands one at a time and press enter for each command: ./configure --enable-universalsdk --enable-framework make make frameworkinstall After this Python should be already install in your computer, and you should be able to use ttk. Remember that to import ttk on version 3.x you should do: import tkinter.ttk I'm in the process of writing a tutorial of Python, maybe it can help you, this is the link: http://web.me.com/charras/Python/Welcome.html Regards!

Python3.1 mac os
by Georges Arsouze July 16, 2011

July 16, 2011

Hi sorry for my poor english 1) I'm working on mac os snow leopard 10.6 and python 3.1 I want to use the ttk and tix widgets I have an error message : require tile On the mailing list i see I think that it is probably much easier to install the *tile* extension for Tk-8.4 than upgrading Tcl/Tk and *Python* to Tk-8.5 . You can look for *tile* packages here: http://sourceforge.net/projects/tktable/files/ and once *tile* is installed you can use ttk just as if you had Tk-8.5 . I hope this helps Michael What can i do for installing tile ? 2)I try pyhon 3.2 from activate state Tcl/tk is in version 5 but idle crash can you help me ? I'm beginning with python regards

tkinter - hopefully forecasting a very long life...

Hi people, I'm midway in writing a simple wiki, in python+tkinter (thanks also to your help, http://old.nabble.com/newbie-request-for-help-td31791699.html). Simple for the typical developer maybe, but for me is long work, and once you start optimizing stuff, it can become a very large project. And suddenly I become prey of doubts: did I chose the right language? >From the POV of being the easiest method I found for writing a program and its GUI, I'm really happy with it. But I intend to use this wiki for many years to come... will tkinter stay with us for so long? What do you think about tkinter's long-term prospectives? thanks for your help! alessandro -- View this message in context: http://old.nabble.com/tkinter---hopefully-forecasting-a-very-long-life...-t… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.
