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

Weird bug in input widgets?
by Raphaël SEBAN Jan. 31, 2015

Jan. 31, 2015

Hi all, While working on my latest software (tkScenarist on GitHub), I encountered a really weird issue: once cleared, input widgets such as Text, Entry, ttk.Entry do *NOT* accept composite-accented letters (french ê, ë, etc) any more. So, to get sure, I made the following test code: [CODE] #!/usr/bin/env python3 # -*- coding: utf-8 -*- from tkinter import * def clear_all (event=None): # clear stringvars for svar in cvars: svar.set("") # end for # clear text widgets for wtext in texts: wtext.delete("1.0", END) # end for # end def def test (nb_of_widgets): global root, cvars, texts root = Tk() root.title("test #{}".format(nb_of_widgets)) cvars = list() for n in range(nb_of_widgets): svar = StringVar() cvars.append(svar) Entry(root, textvariable=svar).pack() # end for texts = list() for n in range(nb_of_widgets): wtext = Text(root, height=2, width=20) wtext.pack() texts.append(wtext) # end for Button(root, text="Clear all", command=clear_all).pack(side=LEFT) Button(root, text="Quit", command=root.destroy).pack(side=RIGHT) # events main loop root.mainloop() # end def if __name__ == "__main__": # launch test series for n in range(1, 4): test(n) # end for # end if [/CODE] Detailed description of the issue: * French keyboards are arranged in such a way that you must compose accented letters as ê (e circumflex) or ë (e diaeresis) by pressing first the '^' key and then the letter to compose with (e.g. a, e, i, o, u, y) in order to get the final composite-accented letter (â, ä, ê, ë, and so on); * when you launch the test script (cited above) and then type, let's say, the e circumflex letter (ê) into the Entry widget and into the Text widget, respectively: * the first time, you'll get the right letters inserted into the input widgets; * then click on 'Clear all' button and enter once again the same composite-accented letter into *ALL* the input widgets; * secund time, only the last pack()-ed input widget will get the right input, all other widgets will show unaccented letters; * the test script tries with 1 Entry and 1 Text input widgets, then with 2 input widgets and finally with 3 input widgets; * each time you get the same issue: only the last pack()-ed input widget shows the right input letter, all the rest showing unaccented letters. This issue is quite embarrassing for me as my latest software manages with movie scenario scriptwriting, which *MUST* be written with correct accents in French, otherwise all the purpose of the software would collapse. Is this a known issue? Thank you for your expert advice. Regards. Raphaël SEBAN alias tarball69.

Tkinter colours lighter on OS X
by Patrick Robertson Jan. 28, 2015

Jan. 28, 2015

I’m having a problem whereby every colour I declare in Tkinter (background colour, font colour etc.) is always a shade lighter when viewed on OS X. Take for example the test code: import Tkinter root = Tkinter.Tk() root.configure(bg="#000000") root.configure(borderwidth=20) root.geometry('%dx%d+%d+%d' % (200, 200, 200, 200)) frame = Tkinter.Frame(root, bg="#444444", borderwidth=20) frame.pack(fill=Tkinter.BOTH) frame2 = Tkinter.Frame(frame, bg="#999999", height=120) frame2.pack(fill=Tkinter.BOTH) root.mainloop() If you run this on OS X and then open up DigitalColor Meter and hover over each box, you will see that the two lighter grey colours don't match what is in the code. If I hover over the the inner square, I get #A9A9A9 (instead of #999999), and the middle square gives #565656 (instead of #444444). I also get the same thing for .gifs I load using Tkinter.PhotoImage(data=…). For images I have tried changing the sRGB/RGB setting of the image to no avail I'm running OS X 10.9 with Python 2.7.8, Tc/Tk 8.5 (Tkinter specifies __version__ = '$Revision: 81008 $') Has anybody else experienced this problem, and if so what is the right fix? Thanks You can see the full question on SO: https://stackoverflow.com/questions/28166029/tkinter-colours-lighter-on-os-x

Text folding of text
by Vasilis Vlachoudis Jan. 22, 2015

Jan. 22, 2015

Dear all, I want to create a text box with folding capabilities. To show/hide lines of text (probably using the elide function) but when I hide the text I want it to be replaced by one line +---- 10 lines folded ---- that extends to the full width of the text widget and the editing is disabled on that line. Is it possible to disable the editing on specific lines/tags? Thanks in advance Vasilis

Re: [Tkinter-discuss] Event debugger

Hi Vasilis and Michael, I thought you could use xev just by starting it in another shell with "xev -id <win_id>". Or do you lose some info by running it this way? (I mean even more than by the other heavy restrictions - they seem to make xev useless for event debugging. I'll have to look at the other tools you mentioned one of these days...) Best Regards, Matthias.

Hello Vasilis, >So my questions is, does it exist any event debugger so I can monitor >the events on a specific widget to find out what happens in between > the two clicks? if your on X11 xev (+ possibly a pipeline through grep) might be sufficient for your debugging needs. I'm not a heavy user of xev, though. Hope this helps, Matthias And Happy New Year to all the list :-)

Help with finding tutors for Python, Linux, R, Perl, Octave, MATLAB and/or Cytoscape for yeast microarray analysis, next generation sequencing and constructing gene interaction networks
by thomas hahn Jan. 4, 2015

*Help with finding tutors for Python, Linux, R, Perl, Octave, MATLAB and/or Cytoscape for yeast microarray analysis, next generation sequencing and constructing gene interaction networks* Hi I am a visually impaired bioinformatics graduate student using microarray data for my master’s thesis aimed at deciphering the mechanism by which the yeast wild type can suppress the rise of free reactive oxygen species (ROS) induced by caloric restriction (CR) but the Atg15 and Erg6 knockout mutant cannot. Since my remaining vision is very limited I need very high magnification. But that makes my visual field very small. Therefore I need somebody to teach me how to use these programming environments, especially for microarray analysis, next generation sequencing and constructing gene and pathway interaction networks. This is very difficult for me to figure out without assistance because Zoomtext, my magnification and text to speech software, on which I am depending because I am almost blind, has problems reading out aloud many programming related websites to me. And even those websites it can read, it can only read sequentially from left to right and then from top to bottom. Unfortunately, this way of acquiring, finding, selecting and processing new information and answering questions is too tiresome, exhausting, ineffective and especially way too time consuming for graduating with a PhD in bioinformatics before my funding runs out despite being severely limited by my visual disability. I would also need help with writing a good literature review and applying the described techniques to my own yeast Affimetrix microarray dataset because I cannot see well enough to find all relevant publications on my own. Some examples for specific tasks I urgently need help with are: 1. Analyzing and comparing the three publically available microarray datasets that can be accessed at: A. http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE41860 B. http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE38635 C. http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE9217 2. Learning how to use the Affymetrics microarray analysis software for the Yeast 2 chip, which can be found at http://www.affymetrix.com/support/technical/libraryfilesmain.affx 3. For Cytoscape I need somebody, who can teach me how to execute the tutorials at the following links because due to my very limited vision field I cannot see tutorial and program interface simultaneously. A. http://opentutorials.cgl.ucsf.edu/index.php/Tutorial:Introduction_to_Cytosc… B. http://opentutorials.cgl.ucsf.edu/index.php/Tutorial:Filtering_and_Editing_… C. http://cytoscape.org/manual/Cytoscape2_8Manual.html#Import%20Fixed-Format%2… D. http://wiki.cytoscape.org/Cytoscape_User_Manual/Network_Formats 4. Learning how to use the TopGo R package to perform statistical analysis on GO enrichments. Since I am legally blind the rehab agency is giving me money to pay tutors for this purpose. Could you please help me getting in touch regarding this with anybody, who could potentially be interested in teaching me one on one thus saving me time for acquiring new information and skills, which I need to finish my thesis on time, so that I can remain eligible for funding to continue in my bioinformatics PhD program despite being almost blind? The tutoring can be done remotely via TeamViewer 5 and Skype. Hence, it does not matter where my tutors are physically located. Currently I have tutors in Croatia and UK. But since they both work full time jobs while working on their PhD dissertation they only have very limited time to teach me online. Could you therefore please forward this request for help to anybody, who could potentially be interested or, who could connect me to somebody, who might be, because my graduation and career depend on it? Who else would you recommend me to contact regarding this? Where else could I post this because I am in urgent need for help? Could you please contact me directly via email at Thomas.F.Hahn2(a)gmail.com and/or Skype at tfh002 because my text to speech software has problems to read out this website aloud to me?
