I am here again.I am sure you can help me.I need any function like destroy which can delete window.The programm you can see on http://poradna.programujte.com/viewtopic.php?t=973 If you run in, You will see a menu.If you open "rozrh hodin" and then you open "prumer" you will see 3 windows.How to delete 2 old windows?I would like see all timees only one window: Here is the programm: from Tkinter

Catching exceptions
by Cam Jan. 31, 2006

Jan. 31, 2006

ProgramA (a Tkinter application) contains this code snippet: try: execfile('programB',{}) except: <code to handle the exception> Where it runs programB. ProgramA would like to catch and handle any otherwise uncaught exceptions in ProgramB. If programB is NOT a Tkinter application then ProgramA does indeed catch and handle exceptions that occur in programB. However, if ProgramB is a Tkinter application then virtually all the action takes place inside callbacks and any exceptions in those callbacks are caught and handled by Tkinter, thus never getting to exception handler in ProgramA. Is there any way to tell Tkinter not to handle exceptions in callbacks so that on an exception in a callback programB would grind to a halt and the exception handler in ProgramA would take over? Or would this violate some fundamental principle of how Tkinter works? Any knowledgable advice on this would be *greatly* appreciated. Cam Farnell If you are wondering what I'm up to, ProgramA is an (under construction) development environment which has produced ProgramB which we would now like to run. If execution of ProgramB goes badly we would like to show a traceback and then be able to take you to the offending line of code. But if Tkinter catches and hides the error, that's hard to do.

Re: [Tkinter-discuss] HTML Viewer

Michael, That's great, thank you! I'll check it out. It may be all I need, if I clip out all the unnecessary HTML from the pages or (if time allows) enhance the viewer a little. The pages I want to view are (relatively) basic, since they contain few images and not a lot of 'fancy formatting'.

That's excellent! It never occurred to me to check whether something like this existed in tcl. At first glance, it looks like the HTML display library with table support ('htmllib3_4.zip') might work, with a Python wrapper. I haven't found much yet on wrapper howtos--but Jeff Epler's PyBwidgets wrapper seems as good a place as any to begin learning how to do this, since the wrapper has so far worked elegantly for me.

I was afraid you might ask that : ). I am working on an application that would allow an end-user to view locally-saved web-pages and print them, if needed. The viewer would not be required to interact with the web. However, all formatting (CSS, etc.) would have to be maintained. Web-pages would also generally include images. I definately would not require a full-fledged browser, just a viewer that allows printing. Am I oversimplifying here? Should a different approach be taken, such as converting the webpage to .pdf?

Hyperterm type program and text box
by Michael Solem Jan. 23, 2006

Jan. 23, 2006

Hello, I want to create a program to talk to the com port (something like hyperterminal or minicom). The display should be a box that outputs characters as they come in (from the port), and accepts characters as input, which it sends to the port. Characters entered on the screen should not be shown on the screen (which is the default behavior of hyperterm and minicom). I was planning on using the Tkinter Text widget for this, but see no way of having the user enter data, without it showing up on the screen. Is there a way to do that? Is there another widget that can do it? Thanks, Mike -- ______________________________________________ Check out the latest SMS services @ http://www.linuxmail.org This allows you to send and receive SMS through your mailbox.

Drawing waveform on a Canvas
by Michael Lange Jan. 19, 2006

Jan. 19, 2006

Hello list, I am trying to draw a graphical representation of a soundfile (a.k.a. waveform) onto a Canvas, however I am not sure where to start. I have used the SnackCanvas before (http://www.speech.kth.se/snack) and it is pretty cool, however for several reasons I don't want to use the Snack package anymore and I wonder how to achieve something like Snack's create_waveform() method in plain Tkinter. Just in case you don't know exactly what I am talking about, a short description of what SnackCanvas.create_waveform() does: When called first on a soundfile, this file is scanned for peak values (which takes a while, on my box here about 70 seconds for a 30 minute wav-file); the information gained herein is then stored in a so called "shape file" (a binary file of unknown format, which is about 600 kB for a 30 minute wav-file) which makes it very fast to load the waveform again later on (about one second). The item returned by create_waveform() can then be treated like any other Canvas item; especially cool features are, that with camvas.itemconfigure(item, height=...) you can stretch the waveform vertically, and with canvas.itemconfigure(item, pixelspersecond=...) you can "zoom" into the waveform horizontally, which is both pretty fast, too. Now, trying to get something similar without Snack, I found there are several ways to scan the soundfile, of which the most promising seems to me the audioop.maxpp() method. I tried to store the information I get from audioop.maxpp() in a reasonable amount of time and ended with a 700 kB text file filled with integer values, and there I am stuck. Does anyone have an idea, if it is possible to put this information together to a usable Canvas item, and if yes, where to go (polygon? image?). Any ideas are much appreciated. Thanks in advance.

Pmw problem in cygwin with Tkinter
by Stewart Midwinter Jan. 14, 2006

Jan. 14, 2006

I have a Tkinter app running on cygwin. It includes a Test menu item that does nothing more than fetch a directory listing and display it in a Toplevel window (I'd use a tkMessageBox showinfo widget, but for some reason the text is invisible on cygwin). After I close the Toplevel widget, all of the menus in my app behave as though they have no contents to them, i..e I can press on the File menu button, and see it depress, but the Exit submenu does not appear (and neither do any of the other menus' submenus). However, a Quit button in my status bar does respond, so the problem lies with the menu. Below are two apps that illustrate the problem. It's obvious that the problem is with Pmw, and in particular with the menubar widget. The first test app uses Pmw, and displays the problem behaviour. The second test app uses basic Tk menus, and does not have a problem. Any clues? --- #test_subprocess3.py from Tkinter import * import os, sys import subprocess programHome = '/cygdrive/c/programs' sys.path[:0] = [programHome] try: import Pmw except ImportError: print 'I need to have Pmw widget set installed in c:\\Programs\\Pmw' sys.exit("missing Pmw") class PumpAdmin(Pmw.MegaWidget): def __init__(self, parent): #master=None): Pmw.MegaWidget.__init__(self, parent) #Frame.__init__(self, master, relief=SUNKEN, bd=2) self.parent = parent def drawGui(self): '''draw the application''' #
