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

Where is tkinter.py
by Pierre Dagenais Dec. 22, 2013

Dec. 22, 2013

Hi, I'm new at this stuff and I'm trying to understand what I'm doing! I thought that when I executed "tkinter import" a file called tkinter.py (a class) would be loaded for execution. Except when I search my system, Ubuntu 12.04, all I find is Tkinter.py in the 2.7 directory, python3.3 has no equivalent tkinter.py? Can somebody explain? TU, PierreD.

Problem with event.widget.grid_info()
by Horace Stoica Dec. 8, 2013

Dec. 8, 2013

Hi, Not sure this is the place to submit such a query, please re-direct me to the correct place. I implemented a simple Lights Out game which works with the old Python 2.6 (and 2.7 in Windows). After upgrading to SUSE 13.1 which comes with Python 2.7.5 I get the following error: *Exception in Tkinter callback** **Traceback (most recent call last):** ** File "/usr/lib64/python2.7/lib-tk/Tkinter.py", line 1470, in __call__** ** return self.func(*args)** ** File "./LightsOut.py", line 28, in mouse** ** grid_info = event.widget.grid_info()** ** File "/usr/lib64/python2.7/lib-tk/Tkinter.py", line 1978, in grid_info** ** self.tk.call('grid', 'info', self._w))** **TypeError: coercing to Unicode: need string or buffer, _tkinter.Tcl_Obj found** * I get the same error with Python 3.3.2 (which also comes with SUSE 13.1). I attached the source code for the game, please run with "./LightsOut 3". Any help would be greatly appreciated. Thanks, Horace
