Facing issue to show the default button Selected on MAC OS - urgent
by YMohan March 30, 2009

March 30, 2009

Hi All, I am using MAC OS 10.5.1 and Python 2.5.1. I want to show the defalut selected button in Tk window. I have two buttons OK and CANCEL. I want to show the by default OK Button selected but I am not able to do the same on MAC environment. The same code works in Windows. I have tried to set the background color of button but no success. Please refer the attached images. First image is MAC window and second one is Window's window. Can anybody tell me what I am doing wrong in below code or how to set the default selected button? I have written the following code - from Tkinter import * def closeApp(): root.destroy() def replySUBJECTNAME(root): print 'Ok clicked' def SUBJECTNAME(root): w=root.winfo_screenwidth() h=root.winfo_screenheight() root.geometry('220x100+%d+%d' % ((w-220)/2, (h-100)/2)) root.title("SUBJECT NAME") btn=Button(root, name="okbutton", text="OK", command=(lambda: replySUBJECTNAME(root))) btn.configure(bg = "blue", fg = "red") btn.grid(row="0", column="0", sticky=NW) btn.bind('<Return>', lambda e:replySUBJECTNAME(root)) btn.focus_set() Button(root, text="Cancel", command=(lambda: closeApp())).grid(row="0", column="0", sticky=N) entry = Entry(root, width = "30", name="entry").grid(row="1", column="0") child = root.nametowidget("entry") child.insert(0, "Subject Name") root = Tk() SUBJECTNAME(root) root.mainloop() Please let me know what I am doing wrong in above code or if any other approach? Thanks in advance.

Announcement: Tka11y 0.1.1 release - Accessibility-aware Tkinter
by Allen Taylor March 25, 2009

March 25, 2009

Tka11y 0.1.1 is released. You can find it at http://pypi.python.org/pypi/Tka11y. Changes from 0.1.0 to 0.1.1: - Added emission of text, text attribute, value, and selection changes. - This enhancement is based on proposed changes to Papi, and therefore will not be realized until a new version of Papi (> 0.0.9) is released. - Fixed reporting of text background color attribute for Entry and Spinbox widgets in the readonly state. - Fixed some value interface bugs in Scale and Scrollbar. - Fixed selection interface bugs in Listbox. - Ensured Entry and Spinbox widgets have an empty name. In the previous version, the name was assigned the initial text contents of the widget, which didn't make much sense. - Made some other minor bug fixes. >From the package description... This module makes it possible for accessibility (a11y) clients (e.g., audible readers, magnifiers, etc.) to get accessibility data (name, description, role, actions, etc.) from the Tk widgets of Python applications that use Tkinter. It also allows automated GUI application testers that use the accessibility interface (such as dogtail, LDTP, and Accerciser) to control the Tk widgets of these applications. Currently, accessibility is only available via ATK <=> AT-SPI on Linux. Sorry, no Windows MSAA support. Enjoy! Allen B. Taylor

From wxPython to TK
by jimscafe March 23, 2009

March 23, 2009

I am a businessman who writes his own software to help run the business. That said I started writing software in Fortran on an ICL mainframe, then on a Commodore pet, then an Apple II. I gravitated towards Python some 6 years ago (via java and perl) and enjoy Python. The gui is another matter. I tried TK at first then for the last 3 years have been using wxPython - I bought a book on it as I find the documentation difficult, not to say irritating at times. This week I decided to try and go back to TK, so I have been writing demo code to make sure that I have the necessary tools to complete the few main applications I already have that use a gui. The frustration with wx is mainly little niggles. There is no doubt it is a wonderful package, but I just find the niggles more and more drustrating. For example, I have decided to try to use linux as my development desktop (mint linux). I like it a lot (from XP) but my finance software needs to be altered a lot using wx - partly it is font problems, but even installing Windows fonts on mint did not solve the display problems. The final problem was the combo box, which behaves differently on Windows and linux and which in the forums I searched there was no satisfactory answer as to how to fix it or why there was a difference. Hence I thought I would go back to basics. My first task was to create a grid widget to display my monthly data by orders, invoices etc. I did this using a grid of labels. A combo box is an OptionMenu(took some time to figure this out satisfactorily). To the more experienced (i.e. people who program for a living), is using tk a sensible decision? I looked at other gui options, but all seemed complicated and not necessarily well documented online. Where am I likely to come across things I need to do that will be impossible in tk (if any)? I have just spent about 10 hours writing demo code in tk and I think I can cover all the applications I have developed in wx. This might take me a week - not really many applications currently in use. And I do feel there is more control in tk over the widget. Not quite sure what I mean by this but because the widgets are more basic it seems easier to use them and then develop them further. My main monthly report I have used the model-view-control approach, so only the view part needs changing. There doesn't seem to be much development going on in tk, is this a potential future problem? Any comments will be much appreciated. -- View this message in context: http://www.nabble.com/From-wxPython-to-TK-tp22595091p22595091.html Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

Problem facing in lift and tkraise urgent
by YMohan March 21, 2009

March 21, 2009

Hi All, I am facing the issues while using the lift or tkraise with create_window objects. its not working. I am trying to do the show one window at a time. I have created two window objects using the create_window and try to launch the first one. The following code I have written from Tkinter import * root = Tk() canvas = Canvas(root, width=300, height=300, bg='white') # 0,0 is top left corner canvas.pack(expand=YES, fill=BOTH) # increases down, right def setAbove(): canvas.tkraise(objectID1) # print "after tk raise" widget1 = Frame(canvas, bg='red', height=100, width=100) widget2 = Frame(canvas, bg='blue', height=100, width=100) objectID1=canvas.create_window(100, 100, window=widget1) # embed a widget objectID2=canvas.create_window(100, 100, window=widget2) # embed a widget root.after(5000, setAbove) root.mainloop() Let me know what am I doing wrong or any other way to do the same? Thanks in advance.

Filling a series of tk.Label
by Iain Day March 19, 2009

March 19, 2009

Hi, I've written a short program which is supposed to populate a table constructed from tk.Label widgets. It does this by looping over the rows. Unfortunately, it only seems to populate the final row. What am I doing wrong? The code is: def updatedata(): updatetime.delete(0, tk.END) for i in range(len(machines)): print machines[i] status = sshshowstat(machines[i]) for j in range(len(status)): param, value = status[j].split(': ') for k in range(len(variables)): if re.match(variables[k], param) is None: continue else: # print i, value if value in ('Acquiring', 'Regulated'): systemdata[i][k].config(text=value, foreground='green') elif value in ('Not Reg.'): systemdata[i][k].config(text=value, foreground='red') else: systemdata[i][k].config(text=value) tk.Button(root, text="Update Table Data", command=updatedata).grid(row=len(machines)+1, column=len(variables), sticky=tk.S) Thanks, Iain

Tkinter: window manager- .resizable
by Madhu Subramaniam March 3, 2009

March 3, 2009

Hello, I work with python 2.5.2 and i use Tkinter for a gui app development. Platform with which i work is:- Linux version 2.6.9-67.ELsmp ( brewbuilder(a)hs20-bc1-5.build.redhat.com) (gcc version 3.4.6 20060404 (Red Hat 3.4.6-8))** #!/usr/local/bin/python #---------------------- from Tkinter import * import pdb import os import string import threading from tkFileDialog import * from tkMessageBox import * import sys main_w = Tk() main_w.resizable(width = False, height = False) #main_w.maxsize(width= 1000, height = 3000) print main_w.resizable() main_w.mainloop() In the above code the command main_w.resizable.... does not work. That means, the user can drag the window to a larger size but cannot make the same smaller. On printing: ------------- print main_w.resizable() i do get 0,0 as output! BUT, the resizable attribute works if i add the following line main_w.maxsize(width= 1000, height = 3000) where the values are random but should not be set to width = 0, height =0, in which case it (widget.resizable(width = False, height = False)) does not function. So is this a bug, or am i doing something wrong here ? :O Regards Thanks arms

The wiki -- spammers and permission to edit
by Jeff Epler March 2, 2009

March 2, 2009

The wiki has been seeing a ton of spam since I upgraded to a modern version of moin (isn't that ironic! perhaps I should downgrade again). Simply requiring users to sign in before editing has also not proven to be enough. I am stuck with Ubuntu Hardy Heron's version of moin, so I can't enable advanced features like TextCha that are in the newest versions of moin. (I am using BadContent and LocalBadContent, but those are useless against the current kind of spam which consist of creating a new page and then putting the actual spam in an attachment to the page!) Therefore, I've chosen to implement a whitelist of approved editors. Create a wiki account if you don't have one yet, and I'll add you to the page ApprovedEditorsGroup. (actually, anyone who is an approved editor can edit this page, and I've added all people who edited pages since 2005). I'm open to better suggestions, again with the caveat that I'm stuck on hardy heron's version of moin, 1.5.8-5.1ubuntu2.2. I'm also open to anyone who is able to take over the wiki and do a better job at technical countermeasures than me, or an initiative to move the information on it to the common Python wiki. I'm sorry for the inconvenience this will cause for everyone who would like to contribute to the wiki. Jeff
