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

Biggest Fake Conference in Computer Science
by eliswilson＠hushmail.com April 30, 2013

April 30, 2013

Biggest Fake Conference in Computer Science We are researchers from different parts of the world and conducted a study on the world’s biggest bogus computer science conference WORLDCOMP http://sites.google.com/site/worlddump1 organized by Prof. Hamid Arabnia from University of Georgia, USA. We submitted a fake paper to WORLDCOMP 2011 and again (the same paper with a modified title) to WORLDCOMP 2012. This paper had numerous fundamental mistakes. Sample statements from that paper include: (1). Binary logic is fuzzy logic and vice versa (2). Pascal developed fuzzy logic (3). Object oriented languages do not exhibit any polymorphism or inheritance (4). TCP and IP are synonyms and are part of OSI model (5). Distributed systems deal with only one computer (6). Laptop is an example for a super computer (7). Operating system is an example for computer hardware Also, our paper did not express any conceptual meaning. However, it was accepted both the times without any modifications (and without any reviews) and we were invited to submit the final paper and a payment of $500+ fee to present the paper. We decided to use the fee for better purposes than making Prof. Hamid Arabnia richer. After that, we received few reminders from WORLDCOMP to pay the fee but we never responded. This fake paper is different from the two fake papers already published (see https://sites.google.com/site/worlddump4 for details) in WORLDCOMP. We MUST say that you should look at the above website if you have any thoughts of participating in WORLDCOMP. DBLP and other indexing agencies have stopped indexing WORLDCOMP’s proceedings since 2011 due to its fakeness. See http://www.informatik.uni-trier.de/~ley/db/conf/icai/index.html for of one of the conferences of WORLDCOMP and notice that there is no listing after 2010. See Section 2 of http://sites.google.com/site/dumpconf for comments from well-known researchers about WORLDCOMP. The status of your WORLDCOMP papers can be changed from scientific to other (i.e., junk or non-technical) at any time. Better not to have a paper than having it in WORLDCOMP and spoil the resume and peace of mind forever! Our study revealed that WORLDCOMP is money making business, using University of Georgia mask, for Prof. Hamid Arabnia. He is throwing out a small chunk of that money (around 20 dollars per paper published in WORLDCOMP’s proceedings) to his puppet (Mr. Ashu Solo or A.M.G. Solo) who publicizes WORLDCOMP and also defends it at various forums, using fake/anonymous names. The puppet uses fake names and defames other conferences to divert traffic to WORLDCOMP. He also makes anonymous phone calls and threatens the critiques of WORLDCOMP (See Item 7 of Section 5 of above website). That is, the puppet does all his best to get a maximum number of papers published at WORLDCOMP to get more money into his (and Prof. Hamid Arabnia’s) pockets. Prof. Hamid Arabnia makes a lot of tricks. For example, he appeared in a newspaper to fool the public, claiming him a victim of cyber-attack (see Item 8 in Section 5 of above website). Monte Carlo Resort (the venue of WORLDCOMP for more than 10 years, until 2012) has refused to provide the venue for WORLDCOMP’13 because of the fears of their image being tarnished due to WORLDCOMP’s fraudulent activities. That is why WORLDCOMP’13 is taking place at a different resort. WORLDCOMP will not be held after 2013. The draft paper submission deadline is over but still there are no committee members, no reviewers, and there is no conference Chairman. The only contact details available on WORLDCOMP’s website is just an email address! We ask Prof. Hamid Arabnia to publish all reviews for all the papers (after blocking identifiable details) since 2000 conference. Reveal the names and affiliations of all the reviewers (for each year) and how many papers each reviewer had reviewed on average. We also ask him to look at the Open Challenge (Section 6) at https://sites.google.com/site/moneycomp1 and respond if he has any professional values. Sorry for posting to multiple lists. Spreading the word is the only way to stop this bogus conference. Please forward this message to other mailing lists and people. We are shocked with Prof. Hamid Arabnia and his puppet’s activities at http://worldcomp-fake-bogus.blogspot.com Search Google using the keyword worldcomp fake for additional links.

Strange 'tate' option in ttk.Treeview.heading

April 16, 2013

Hello, I'm getting an strange 'tate' property when calling treeview.heading() function. Here is an example: #----- import sys import tkinter as tk import tkinter.ttk as ttk print('Python version:', sys.version_info) print('tk version:', tk.TkVersion) print('ttk version:', ttk.__version__) root = tk.Tk() columns = ('A', 'B', 'C') tv = ttk.Treeview(root, columns=columns ) for col in columns: tv.heading(col, text=col) tv.heading('#0', text='Root') tv.grid() #get heading properties properties= tv.heading('A') # Print strangeous 'tate' property print("strange 'tate' option", properties) properties['anchor'] = tk.E #error trying to set properties tv.heading('A', **properties) root.mainloop() #end This is the output: Python version: sys.version_info(major=3, minor=3, micro=1, releaselevel='final', serial=0) tk version: 8.5 ttk version: 0.3.1 strangeous 'tate' property {'image': '', 'anchor': 'center', 'tate': '', 'command': '', 'text': 'A'} Traceback (most recent call last): File "../tkinter/tate-issue.py", line 24, in <module> tv.heading('A', **properties) File "/usr/lib/python3.3/tkinter/ttk.py", line 1268, in heading return _val_or_dict(kw, self.tk.call, self._w, 'heading', column) File "/usr/lib/python3.3/tkinter/ttk.py", line 311, in _val_or_dict res = func(*(args + options)) _tkinter.TclError: unknown option "-tate" Where this option comes from? Can someone try on another python version? Maybe this is a Bug? Regards Alejandro A

Hi All, I've attaached code simplified from my "opus" and have a problem. I would like to exit from "read_sensor" into the main loop.

question on winfo_height
by GKalman April 10, 2013

April 10, 2013

Please look at the following Tkinter code fragment: #*** frm=Frame(root,bg="cyan") frm.pack(side=TOP, fill=BOTH, expand=YES) h= frm.winfo_height() print h, type(h) #*** It returns a value of h=1 and type= int I remember seeing somewhere that the returned a value of h=1 means that it is RELATIVE wrt something. Question: how can I get the ABSOLUTE value for height. BTW: h= frm.cget("height") print h results in a value of h=0 !!! why? -- View this message in context: http://python.6.x6.nabble.com/question-on-winfo-height-tp5013753.html Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

Tcl/TK issue with viewVC (UNCLASSIFIED)
by Glasgow, Steven R CIV USARMY TRADOC ANALYSIS CTR (US) April 1, 2013

April 1, 2013

Classification: UNCLASSIFIED Caveats: NONE I'm currently having problems using viewVC which depends on both python and Tkinter. I was hoping anyone could tell me why I'm getting the following set of messages from the "viewvc/bin/standalone.py -g -r $CVSROOT" command. I'm using version 1.1.18 of viewVC, and 2.6.6 of python...Not sure how to find the version of Tkinter I'm using. We are in the process of upgrading from RHEL 5.4 to RHEL 6.3. Everything works just fine on RHEL 5.4 but not RHEL 6.3. In addition to the following messages, the ViewVC standalone window comes up, but always says "starting server" and the open browser button is never activated. Here are the messages: Exception in thread Thread-1: Traceback (most recent call last): File "/usr/lib64/python2.6/threading.py", line 532, in __bootstrap_inner self.run() File "/usr/lib64/python2.6/threading.py", line 484, in run self.__target(*self.__args, **self.__kwargs) File "/awars2a/Applications/viewvc/viewvc-1.1.18/bin/standalone.py", line 421, in serve ViewVCHTTPServer(host, port, callback).serve_until_quit() File "/awars2a/Applications/viewvc/viewvc-1.1.18/bin/standalone.py", line 349, in __init__ BaseHTTPServer.HTTPServer.__init__(self, self.address, self.handler) File "/usr/lib64/python2.6/SocketServer.py", line 403, in __init__ self.server_activate() File "/awars2a/Applications/viewvc/viewvc-1.1.18/bin/standalone.py", line 361, in server_activate self.callback(self) File "/awars2a/Applications/viewvc/viewvc-1-1-18/bin/standalone.py", line 671, in ready self.title_lbl.config(text='ViewVC standalone server at\n' + server.url) File "/usr/lib64/python2.6/lib-tk/Tkinter.py", line 1202, in configure return self._configure('configure', cnf, kw) File "/usr/lib64/python2.6/lib-tk/Tkinter.py", line 1193, in _configure self.tk.call(_flatten((self._w, cmd)) + self._options(cnf)) TclError: out of stack space (infinite loop?) I first tried getting support from the viewVC community, but were told, "Looks like a problem in the Tcl/TK Python bindings." They thought I might want to raise my issue with the community that maintains those bindings and that maybe someone there might quickly recognize the problem and give me (or the viewVC community) immediate feedback on a solution. Any help would be appreciated. Thank you, Steve Classification: UNCLASSIFIED Caveats: NONE

class_ attribute on ttk widgets
by Alejandro Autalan April 1, 2013

April 1, 2013

Hello all. I'm reading the tkinter reference at http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/index.html. It says that the 'class_' attribute is available for ttk widgets. But when is set, some widgets become unresponsive. Example: #uname -a Linux vostro1 3.2.0-4-amd64 #1 SMP Debian 3.2.39-2 x86_64 GNU/Linux # Python 3.2.3 #tkinter.TkVersion 8.5 import tkinter as tk from tkinter import ttk f = ttk.Frame() f.grid() entry = ttk.Entry(f, class_='CustomEntry') entry.grid() btn = ttk.Button(f, class_='CustomButton', text='Button') btn.grid() f.mainloop() When I run the example, I can't enter text on entry widget or click a button. Is this the expected behaviour? Anyone know how this attribute should be used for ttk widgets ? Thanks.
