True. This annoyed me so much, though, that I researched it a tiny bit more. The Img extension, as it happens, can snapshot a canvas into a photo, and Tkinter itself can report on the pixel values in a photo image. That's as good as it gets, apparently. What I don't know is whether Tkinter supports Img at all; I must confess that I'm only aware of its availability for Tcl/Tk.

If so, I have used it successfully by just adding a line root.tk.call('package', 'require', 'Img') (where root of course is my Tk() window). I have only used it for displaying .png images though, I don't know about this "snapshot" feature.

When I run it as 'python entry.py' on linux, both 'e1' and 'e2' appear perfectly except I cannot enter any character in 'e1' entry, but 'e2' entry is ok. Second, when I run it in python interactive shell LINE BY LINE, then 'e1' and 'e2' entry both can accept user input, no problem! But when I copy and paste it into interactive shell, then the first situation happens again. So..., has anyone ever run into this problem like me? and how do you fix it? I use python2.3.4 now.

From Tkinter.py it looks to me like it should be equivalent: def mainloop(n=0): """Run the main loop of Tcl.""" _default_root.tk.mainloop(n) (...snip...) class Tk(Misc, Wm): """Toplevel widget of Tk which represents mostly the main window of an appliation. It has an associated Tcl interpreter.""" _w = '.' def __init__(self, screenName=None, baseName=None, className='Tk'): global _default_root (...snip...) if _support_default_root and not _default_root: _default_root = self so _default_root is the Tk() instance. Unfortunately this does not explain what is going wrong in the example.

Fernhout) Date: Thu, 06 Jul 2006 10:12:02 -0400 Subject: [Tkinter-discuss] PataPata as a Tkinter-based GUI designer Message-ID: <44AD1A32.6060109@kurtz-fernhout.com> Version 0.2.02 of PataPata has just been released on SourceForge. PataPata is an experiment about making a live Python object environment of Prototypes and Morphs. It is intended mainly to support building educational simulations and other microworlds for informal "constructivist" education and "unschooling". It has previously been discussed on the edusig list, but perhaps some people here might also find it of interest for the Tkinter-related aspects. The primary GUI interface is currently written in TK/Tkinter, and supports interactively building TK-related projects (though only ones under the GPL for now). My focus on Tkinter at this point is mainly for easy installability, although the value of the TK library has been growing on me as I use it more. Almost two years ago, Eric Brunel posted this comment on Tkinter GUI building: http://www.codecomments.com/archive284-2004-10-305528.html and I think the PataPata approach might potentially address the issues he raises there on the need for better Tkinter GUI designer which can support a wide range of widgets for multiple TK-related libraries. Basically, as part of a larger effort to bring some of the more dynamic qualities of Self and Squeak to Python, PataPata brings "prototypes" with "properties" (beyond the Python properties) to Python programming. This makes it easier to wrap arbitrary GUI components, whether existing Tkinter widgets, adding pure TCL/TK widgets (an example for that is included in the latest 0.2.02 for a combobox and tablelist), or, theoretically (as I haven't tried it yet), addign widgets from PMW, Tix, BWidgets, and so on. Or, in theory, and not at the same time as using TK widgets, even widgets from WX, GTK, or whatever could be wrapped. PataPata had an earlier and simpler WX GUI which has not been kept up-to-date, but used the same wrapping approach, providing some hopes for cross-platform GUIs. I know there are many efforts related to that kind of support already (AnyGUI, PyUI, etc.), of course, though I think they come at it from a different perspective, and their widgets could also in theory be wrapped in PataPata as well. Another included example wraps an "xturtle" widget (an advanced version of a 2D turtle by Gregor Lingl as a sophisticated library using Tkinter). There is still no way around doing some hand-coding wrapping work for each widget, but PataPata provides at least a framework for doing that work and for being able to get started with it easily to do some simple wrapping of a widget, and then add more wrapping as more functionality is needed. There is limited PythonCard compatibility as well, as I chose to use PythonCard naming conventions for access to many features of the Tkinter widgets. This limited compatibility may make it somewhat easier to port some simple PythonCard applications to Tkinter, though it still takes a bunch of work (one example of doing this for the PythonCard sample "conversions" is included) and many PythonCard widgets are not yet supported. But you can at least take a PythonCard resource file and convert it to PataPata if all the widgets types used are supported, as a start to then doing hand coding for the rest of the functionality (which is a tribute to PythonCard's modular design). Now there may well be other approaches to the issues Eric Brunel brought up, so this isn't to say PataPata is intended primarily to solve these issues, just that in addition to its main purpose of bringing to Python the notion of Prototypes and Morphs (that Squeak and Self have to varying degrees), PataPata also provides an approach to handling those other issues, which may be of interest to Tkinter users. Here is the project web site: http://sourceforge.net/projects/patapata/ Screenshots: http://sourceforge.net/project/screenshots.php?group_id=165910 A homepage with links to more information (including screencasts by Francois Schnell): http://patapata.sourceforge.net/ I had to resolve a few tricky Tkinter-related issues in the process, and the archives of this list were very useful, thanks. :-) Anyway, PataPata is still very much an experiment and work in progress, so this isn't intended to convince you to move all your Tkinter work in it, just to mention it as something being played with at the moment. There remain lots of things to do for it and lots of ways it can be improved (and probably some bugs too, of course. :-) --Paul Fernhout From bwmetz at att.com Fri Jul 7 00:16:30 2006 From: bwmetz at att.com (Metz, Bobby W, WWCS) Date: Thu, 6 Jul 2006 17:16:30 -0500 Subject: [Tkinter-discuss] Tkinter TopLevel transparency Message-ID: <01D5341D04A2E64AB9B3457690473367020D7C41@OCCLUST01EVS1.ugd.att.com> All, Looking for help on making my toplevel window backgrounds opaque or transparent.

I currently happily set the font sizes using tuples ``font=("name", "size", "weight")``. (or something like that.) I use a couple of different sizes for titles, subtitles, body text and buttons. I would like to detect the system font size, so that I can respond to this. (In case the user has specified larger fonts). Does anyone know how I can do this ? Oh, and while I'm on the subject, does anyone know of a pure Python combobox other than the Pmw one ? The Pmw one is fine, it just means distributing the Pmw extension with my application, and if I could replace this with a single file I would.

As to your combobox question, I don't use pmw but the combobox should be fairly simple to create. To refresh my mem on it I looked up examples of the two types, simple & dropdown. The simple version would be pretty easy to do with a label and listbox. The dropdown version would be harder, but if you don't care about the arrow icon and don't need to select multiple items in the combobox dropdown, then an OptionMenu would be the way to go. Another thing to consider is tying a ListBox to a Button or MenuButton. I've never tried this but I believe I've seen others on the web say it can be done.

You can find it at: www.8ung.at/klappnase/TixGrid/TixGrid.html . The zip-file includes a short test script with code examples and most of the methods and options are documented in the source. Although some of the tixGrid commands seem to have no effect (and due to the poor tix documentation I could not figure out the use of some commands) it may be not too bad at least for simple table display tasks. If anyone has a use for it, it would be nice, if you would report your experience with it here. Maybe after some more testing it could be something to contribute.

Just moving the player on a canvas. Why is that one in Tkinter so slow? What did I miss? Livewires is based on Tkinter, so it should be the same. I looked at the code of Livewires, tried something, but no success. Maybe its because of sleeping part in event handler in Tkinter, that is somehow (how?) bypassed in Livewires by magic tkinter.dooneevent(tkinter.DONT_WAIT). Neither this worked with me. Could anyone help? Both programs attached. -- geon Pavel Kosina -------------- next part -------------- A non-text attachment was scrubbed...
