Animation using image sequence
by Nemes Andrei Dec. 22, 2009

Dec. 22, 2009

Hi! I'm trying to make an animation using a sequence of gif images and the canvas widget, but all I see when I compile is a black screen. What I'm trying to do is delete the previous image and create the next one each frame. Am I doing it wrong? Is it do-able at all? Help would be greatly appreciated. Thank you. #Working on window interface of soundAsleep #Tkinter will handle the GUI from Tkinter import * import time root = Tk() root.title("soundAsleep beta") frame=[] currentframe=0 #Importing the images. They are named w1.gif, w2.gif...w7.gif for i in range(1,7): fname="core/working/w"+str(i)+".gif" frame+=[PhotoImage(file=fname)] wrap = Canvas(root, width=200, height=120) wrap.pack() #trying to make the animation while True: ani=wrap.create_image(100,70,image=frame[currentframe]) time.sleep(5) wrap.update_idletasks() #Force redraw wrap.delete(ani) if (currentframe==5): currentframe=0 else: currentframe+=1 root.mainloop()

How to open a file from Tkinter window?
by Marsel Dec. 20, 2009

Dec. 20, 2009

Hi, I'm new in python and I'm not very familiar with a lot of stuff, so please answer as simple as possible if you will :). The thing is, I would like to make connection betwen a few windows, in this case calculating programs, so I could open any of them from one window or just switch between them in tab - style. I'we also been trying to do it with a button, but in every case I've run out of ideas... I was looking for information everywhere, but as I've said, I don't understand most of the python expressions and was unable to find anything useful... So how can I "connect" or open files from inside a program? Any help would appreciated, thank you. -- View this message in context: http://old.nabble.com/How-to-open-a-file-from-Tkinter-window--tp26858702p26… Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

withdraw() not working when changing virtual desktop
by Michael Lange Dec. 5, 2009

Dec. 5, 2009

Hi all, I encountered a strange problem here; the system is debian linux, it happens both with python-2.5.2 and with python-2.4.6 with tk-8.4.19 as well as with tk-8.5.3; I tried a few different WMs, I can only reproduce the bug with IceWM (1.2.35), on KDE and XFCE it did not occur. The problem is, that withdraw() does not work when the window in question is on another virtual desktop than the currently active. This is annoying if there is for example a dialog window with a progress bar that shows the progress of a process that takes some time, and when the process has finished the dialog should automatically disappear; if the user switches to another desktop while the process is running the dialog stays on the screen. The simplest code to exhibit the bug is something like: from Tkinter import * root = Tk() top = Toplevel() def test(): root.after(5000, top.withdraw) b = Button(root, text='test', command=test) b.pack(padx=100, pady=100) root.mainloop() When I press the button and then switch to another desktop the toplevel is not withdrawn. Has anyone ever heard about this, is this only a bug in IceWM and is there a possible workaround ? Regards Michael

Cursor coordinates
by Vasilis Vlachoudis Dec. 5, 2009

Hi all, I have a canvas with some editable text (with create_text) in it. How can I get the cursor coordinates x,y from the canvas? The index() function returns only the character index, is there a way to convert the position of a character into x,y coordinates or bbox? Vasilis

Python with Snack
by chachachacha Dec. 4, 2009

Hi everyone, I have been trying to install the Snack library (so I can run it with Python 2.5.4). I have Windows Vista and have been trying to install through the command line. I have downloaded the source release for Snack Version 2.2.10 from the page http://www.speech.kth.se/snack/download.html The downloaded folder is on my desktop in a folder called snack. Through the command line, I tried to install the program: C:\Users\user\Desktop\snack\python\setup.py install It returns with: running install running build running build_py file tkSnack.py (for module tkSnack) not found file tkSnack.py (for module tkSnack) not found running install_lib warning: install_lib: 'build\lib' does not exist --no Python modules to install running install_egg_info Writing C:\Python25\Lib\site-packages\tkSnack-2.2.10-py2.5.egg-info I've also just tried to do: C:\Users\user\Desktop\snack\python\python.py install This didn't work either I am very inexperienced in programming but am very eager to learn. I know this is something really simple but it would be great if someone could point out what I am doing wrong.
