Monte; I don't know that. Maybe somebody from here might be able to answer that, but I don't know. I'm kinda new into Tkinter as well. I have less than a year using it. What I told you was what worked for me. And yes, what worked for me was installing source, which I download from here: http://www.python.org/download/ I don't understand as well, why the Mac Os x Installer Disk Image don't come already with Tk/Tcl 8.5, specially since the Windows installer already comes with all that ready, but well. I would even suggest that Python should come with ttk. Those anybody knows what Python doesn't comes already with ttk? Why the Mac installer doesn't have Tk/Tcl as part of the installation? But anyway Monte, in the mean time, try what I suggest. For me works just fine. As I told you before, if you need detail instructions on how to install Python and ttk from source, let me know.

Monte, do you have python 3.1 or 2.6.5. I had a mac as well, and when I try to use ttk didn't work. They way I solve was to copy the ttk.py file inside of the site-packages, which in my case is inside of: Library/Frameworks/Python.framewors/Versions/2.7/lib/python2.7/site-packages Than, what I will recommend is to install from the source, not the installer disk image. If you install from the installer disk image, once you try to use ttk, you will see that the Tk and Tcl connected to ttk are version 8.4, which will not work. If you need details instructions on how to install from the source let me know. I hope this helps. Regards!

Re: [Tkinter-discuss] Canvas.postscript() fails to render some fonts properly

Hello, It looks like that postscript() function cannot render every font with no obvious reason. "Renderable" fonts are rendered correctly regardless of whether they contain spaces or not... However it seems that, alternatively, we can achieve what we want through the Image, ImageDraw and ImageFont modules. All we need to know is the name of the .ttf file to which the font name corresponds. Here is the code: http://paste-it.net/public/t66c5c0/ Please note that I wrote this code on an XP machine. Considering that you are on Debian, this little how to might be of help to you for configuring TrueType fonts: http://www.faqs.org/docs/Linux-mini/TT-Debian.html Firat 2010/8/24 Michael Lange <klappnase(a)web.de> > Hi Firat, > > Thus spoketh Firat Ozgul <ozgulfirat(a)gmail.com> > unto us on Tue, 24 Aug 2010 12:51:48 +0300: > > > Hello, > > > > I found some useful stuff at: > > http://www.tcl.tk/man/tcl8.4/TkCmd/canvas.htm(Find<http://www.tcl.tk/man/tcl8.4/TkCmd/canvas.htm%28Find>"-fontmap" there) > > > > The above document recommends a notation like: * > > -*-Courier-Bold-R-Normal--*-120- > > > > *I think this notation will be like this for those fonts that have > > spaces: > > > > *"-*-DejaVu Serif Condensed-Bold-R-Normal--*-120-*" > > I have already seen this, too, however this does not change anything :( > Using "-*-comic sans ms-Bold-R-Normal--*-240-*" the font is displayed > correctly as always,but not in the postscript :( > > Thanks for all your efforts ! > > Michael > > > .-.. .. ...- . .-.. --- -. --. .- -. -.. .--. .-. --- ... .--. . .-. > > "I'm a doctor, not a mechanic." > -- "The Doomsday Machine", when asked if he had heard of > the idea of a doomsday machine. > "I'm a doctor, not an escalator." > -- "Friday's Child", when asked to help the very pregnant > Ellen up a steep incline. > "I'm a doctor, not a bricklayer." > -- Devil in the Dark", when asked to patch up the Horta. > "I'm a doctor, not an engineer." > -- "Mirror, Mirror", when asked by Scotty for help in > Engineering aboard the ISS Enterprise. > "I'm a doctor, not a coalminer." > -- "The Empath", on being beneath the surface of Minara 2. > "I'm a surgeon, not a psychiatrist." > -- "City on the Edge of Forever", on Edith Keeler's remark > that Kirk talked strangely. > "I'm no magician, Spock, just an old country doctor." > -- "The Deadly Years", to Spock while trying to cure the > aging effects of the rogue comet near Gamma Hydra 4. > "What am I, a doctor or a moonshuttle conductor?" > -- "The Corbomite Maneuver", when Kirk rushed off from a > physical exam to answer the alert. >

python 3.1 - tkinter 8.4 - no tile?
by David Cortesi Aug. 27, 2010

Aug. 27, 2010

Hello. I'm beginning to explore Python 3 and tkinter (using Mac OSX 10.6). Following the directions in (http://wiki.python.org/moin/TkInter) I verified that >>> import tkinter >>> tkinter._test() does indeed open a little window as expected. So there is SOME fashion of tkinter and TCL/TK installed on this machine. Next I attempt to run the "First (Real) Example" in ( http://www.tkdocs.com/tutorial/firstexample.html), but get the error, File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/tkinter/ttk.py", line 47, in _load_tile master.tk.eval('package require tile') Looking at the ttk.py file I find it checks tkinter.TkVersion < 8.5, and in fact tkinter.TkVersion yields 8.4. Performing the following google search, site:mail.python.org 'package require tile' I observe that this same error has been mentioned 66 times over the last few years and with several versions of Python and different platforms. (It seems odd, when this problem has been arising since 2004, the latest version 3.1.2 of Python is still distributed with tkinter 8.4 and yet no tile package. But I digress.) The usual advice is to install the tile package from sourceforge. So I tried to do this but encountered several problems, beginning with, where, ie what folder? Doesn't really matter, as I find that its ./configure script looks for a C compiler -- and the Apple Developer package is not installed on this system. I looked around in /bin and /usr but there doesn't seem to even be a lowly cc anywhere. I'd appreciate any suggestions to get past this stone wall. Thanks, Dave Cortesi

Re: [Tkinter-discuss] Entry Widget that can't enter into at first.

I tested the original poster's code on Ubuntu Karmic Koala (GNOME). As soon as the file dialog is closed, the entry widget is ready for typing. So it seems that this problem is specific to Windows OS. 2010/8/24 Cameron Laird <Cameron(a)phaseit.net> > On Tue, Aug 24, 2010 at 03:36:56PM +0300, Firat Ozgul wrote: > . > . > . > > I could reproduce the error on a Windows XP machine.

Entry Widget that can't enter into at first.
by wet_colored)arch Aug. 24, 2010

Aug. 24, 2010

What basically happens is if I use the application all features work fine except the entry widget I have created. I cannot add text or even get the cursor to appear in the entry field. What is odd is I have a askyesno button for quiting. If I hit "no" and return to the application, I can then enter text and move the cursor with the tab to other features and buttons in my gui. How do I get the entry box to work? The problem might be tied to windows, frames and parents (which I still don't fully understand even though I have built 5 gui's now). The relevant code is abridged as below: if __name__ == '__main__': root = Tk() root.title('Artifact Pointer')# adapted from_PyView 1.0') Label(root, text="Point to Artifacts Observed").pack() SlideShow(root, picdir=picdir, artdir=artdir, bd=3, relief=SUNKEN) root.mainloop() preceeded by: class SlideShow(Frame): def __init__(self, parent=root, picdir='.', artdir='.', msecs=3000, **args):#msecs is legacy Frame.__init__(self, parent, args) self.parent = root self.makeWidgets() and under def makeWidgets I have: self.vent=StringVar() Entry(self,textvariable=self.vent).pack() I have tried some variants and have read several forums and Lutz and still am not getting this sorted out. It is odd to me that it works, but only AFTER, I hit no under askyesno button. -- View this message in context: http://old.nabble.com/Entry-Widget-that-can%27t-enter-into-at-first.-tp2944… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

Canvas.postscript() fails to render some fonts properly
by Michael Lange Aug. 24, 2010

Aug. 24, 2010

Hello all, I am stuck here with a strange problem creating postscript from a Tkinter Canvas (the OS is debian linux). I found that Canvas.postscript() fails to render some fonts correctly and uses something like helvetica or courier (I guess) instead. From what the canvas man page says, I thought I should try to add a fontmap to the postscript() command, but I cannot seem to get it working, and I am not sure if it is because of improper use of the fontmap option or if something else is wrong. >From the few Tcl resources I could find I tried to set up a minimal tcl example, trying to find out how the "fontmap" works, because I could not find any useful Python resources: canvas .c -width 300 -height 300 -bg white pack .c set fonty [font create -family "comic sans ms" -size 16] .c create text 20 20 -font $fonty -text "ich wollt ich waer ein huhn" -anchor nw set fontMap($fonty) [list "comic sans ms" 16] update idletasks .c postscript -file "~/test.ps" -fontmap fontMap However this produces an obviously broken postscript file that cannot be opened. If I omit the -fontmap option, the file can be opened, but I get a font like helvetica or so. Does anyone have a clue on this?

Multiple windows, accessing variables across them won't work for me (Using Tkinter)

Hi! I've been working on this app last days, and can't get passed this problem: I've created two windows, (one is created by a button click in the first window), and from the other window I want to change some variables defined in the first window. I'm guessing either I haven't understood the whole parent thingy, or messed up somewhere there.

update of elements in GUI

Aug. 19, 2010

I have some elements on the screen (Labels, most importantly) which content has to be updated every iteration of the algorithm run, e.g. "Iteration =" [i] for i in range(n). I've tried using mainframe.update_idletasks() and Label(mainframe.update_ideltasks(),textvariable=var).grid(column=1,row=1), but without success so far. In MATLAB this command is drawnow. thanks
