Possibly n00bish question about ImageTk
by Barnesdesdes Feb. 10, 2009

Feb. 10, 2009

I've been trying to make a program which will import a png file and display it inside a frame. It actually works when I just run the code, but if I try to abstract the exact same code into a function, it fails. In the code below, if I just run it, it works. However, if I comment out the lines between "root=Tkinter.Tk()" and "moo(root)" and comment in "moo(root)", it no longer works. Instead of displaying the image, it just displays a gray frame of the correct size. Does anyone have any insights about what I'm doing wrong? import Image, ImageTk, Tkinter def moo(master): img = Image.open('plotfig.png') f = Tkinter.Frame(master, width=800, height=600) pi = ImageTk.PhotoImage(img) t = Tkinter.Label(f, image=pi) f.pack() t.place(x=0, y=0, width=800, height=600) t.pack() root = Tkinter.Tk() img = Image.open('plotfig.png') f = Tkinter.Frame(root, width=800, height=600) pi = ImageTk.PhotoImage(img) t = Tkinter.Label(f, image=pi) f.pack() t.place(x=0, y=0, width=800, height=600) t.pack() #moo(root) root.mainloop() Thanks very much.

Running GUI from console and quitting it

ust create the root window yourself to have control over it and withdraw it: from Tkinter import * import tkMessageBox r = Tk() r.withdraw() tkMessageBox.showwarning( "Output check", "Output is not on") a= raw_input('hit key to continue') Regards, David Excellent. This is exactly what I wanted. Thanks.

Running GUI from console and quitting it
by Amit Finkler Jan. 31, 2008

Jan. 31, 2008

Hi all, I wrote a short code in Python in which I check some boolean flag. If it's true, everything is OK. If it's false, I wanted it to pop-up a warning message on the user's screen. To implement this with Tkinter I naively tried to use tkMessageBox: tkMessageBox.showwarning( "Output check", "Output is not on") However, once the user presses the OK button, the root Tk() window remains. Note that in no place in the code did I create a Tk() instance. The only Tkinter instance is the MessageBox. Is it possible to run some console-based script which pops-up a GUI window and then by pressing OK just kill/destroy it? Thanks, Amit.

Re: [Tkinter-discuss] Threads and GUI

Hello Bob, You wrote: >Is there anything that is OK for a thread to do to the GUI? Like >would just calling .update() on a Button() be OK? It seems to work, >but is it OK? >I'm calling it on a "Stop" button, specifically, in the thread every >quarter second, instead of peppering the code with updates() to give >the button a chance to set it's IntVar value and then stop everything >when the code gets around to checking that. From what I remember everybody says: Don't do that! Some refs I found googling for 'tkinter and threads': A clear warning http://mail.python.org/pipermail/tkinter-discuss/2005-February/000313.html (the cited reference is dead, though) In the following answer is a small example using threading. Another example using thread and Queue (from effbot): http://effbot.org/zone/tkinter-threads.htm I have used a solution from Mark Lutz (Programming Python/O'Reilly) but just for popup dialogs that block the GUI while a thread is running (communicating via a simple variable). This might be applicable to your scenario, too. In a socket testing application I have used 'after' in the GUI thread to look at a common buffer if new data have arrived. BTW have you found some info regarding your signals problem? Hope this helps, Matthias Kievernagel (mkiever/at/web/dot/de)

Question on moving a scale value via the program
by Charlie Hall Jan. 26, 2008

Jan. 26, 2008

Hi, I'm fairly new at Python and even newer at Tkinter. For learning purposes, I'm attempting a program for a small, simple timer. I decided to use the Scale widget to indicate the status (or lapsed time). However, I can't seem to get the Scale widget to respond to a change in scale value. It seems that Scale is intended to respond to key clicks only. Is this correct. If someone knows how I can change the scale value from my program, I'd certainly appreciate some hints. Thank you very much, Charlie Hall
