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

Tkinter multiple font sizes in same text input
by Stewart Baskin April 30, 2016

April 30, 2016

Hello, Thank you in advance for your assistance with this query. I would like to produce multiple font sizes on the same line. For example: ## mg/l I know how to assign the font type/size, but am unable to do this twice (only the second text and font size appear in the window). Is it possible to assign multiple font sizes to the same line in Tkinter? Thank you, Stew

Re: [Tkinter-discuss] standard tkinter command set

Could you provide me with a link to the list of the standard tkinter/tcl command set? I had to put up with the snarkoids at Stack Overflow before one (unintentionally!) informed me that the Text widget has its own native bindings for cut, copy and paste, and that i had wasted time wrapping them in my application. Before I go through that again I'd like to be properly informed about the features. Thanks for all replies. Mickey

Help/advice needed for Tkinter related JyNI issue
by Stefan Richthofer April 5, 2016

April 5, 2016

Hello everybody, I am the author of the JyNI-project (www.jyni.org) which aims to support native CPython extensions in Jython. Some basic Tkinter stuff is known to work with JyNI on Linux, but unfortunately hangs on OSX: https://github.com/Stewori/JyNI/issues/4 In this thread we collected everything we know about this issue so far. The issue is rather strange in the sense that the sample works well on Linux, while it hangs on OSX. Briefly speaking, on OSX TCL/TK does not produce a particular event the loop is waiting for and does not display the window. However logging suggests that calls to TCL/TK API are identical between Linux and OSX runs, so we are really stuck here in finding out what is different on Linux (our current logging does not cover function argument values though). I think there must be something subtle JyNI is doing wrong and that only manifests on OSX. (Running with CPython the sample succeeds on that system.) Any advise how I can find the reason for the missing event would be helpful. My usual divide and conquer debugging approach struggles here because I don't know enough about TCL/TK to trace the cause for the issue through its API. Is there something like an internal log of TCL accessible? Or a way to see the events processed by TCL_DoOneEvent? Thanks in advance for any helpful hint. Stefan
