IDLE Crashes when Prefs are accessed on Python 3.3 on OSX 10.8.2
by Scott Clausen Oct. 12, 2012

Whenever I attempt to access the IDLE prefs the app crashes. I want to be able to enlarge the text for my old eyes. I've looked on the python website with no luck and have removed the current Python file and reinstalled with no luck I'm using the Tk/Tcl that comes with the OS, I believe. Could their be a need for an update that I'm not aware of? Thanks, Scott --- People are taking their comedians seriously and their politicians as a joke. — Will Rogers

Tkinter ttk question
by wrw＠mac.com Oct. 3, 2012

This may or may not be the best place to ask this, but here goes: I'm exploring different GUI packages for python programs I'm writing. I've played a bit with wx and now am exploring Tkinter and ttk 8.5 following the tutorial at http://www.tkdocs.com/tutorial. The first example program is pasted in below: #!/usr/bin/env python from Tkinter import * import ttk def calculate(*args): try: value = float(feet.get()) meters.set((0.3048 * value * 10000.0 + 0.5)/10000.0) except ValueError: pass root = Tk() root.title("Feet to Meters") mainframe = ttk.Frame(root, padding="5 5 5 5") # padding order: West, Top, East, South mainframe.grid(column=0, row=0, sticky=(N, W, E, S)) mainframe.columnconfigure(0, weight=1) mainframe.rowconfigure(0, weight=1) feet = StringVar() meters = StringVar() feet_entry = ttk.Entry(mainframe, textvariable=feet, width=9) feet_entry.grid(column=2, row=1, sticky=(W, E)) meters_entry = ttk.Entry(mainframe, textvariable=meters, width = 9) meters_entry.grid(column = 2, row = 2, sticky =(W, E)) ttk.Button(mainframe, text="Calculate", command=calculate, default = "active").grid(column=3, row=3, sticky=W) ttk.Label(mainframe, text="feet").grid(column=3, row=1, sticky=W) ttk.Label(mainframe, text="is equivalent to").grid(column=1, row=2, sticky=E) ttk.Label(mainframe, text="meters").grid(column=3, row=2, sticky=W) for child in mainframe.winfo_children(): child.grid_configure(padx=5, pady=5) feet_entry.focus() root.bind('<Return>', calculate) root.mainloop() Quoting from the explanation: Next, we create a frame widget, which will hold all the content of our user interface, and place that in our main window. The"columnconfigure"/"rowconfigure" bits just tell Tk that if the main window is resized, the frame should expand to take up the extra space. The problem I'm having is that this doesn't work. If I resize the window, the light gray background doesn't expand with the root window. I get a light gray patch the size of the original frame, but it is surrounded by white space. Can anyone tell me what I'm doing wrong. 64-bit Python 2.7 from python.org and I believe, but can't confirm, that Tkinter and ttk are from Active State. Mac OS X 10.8.2, 2 x Quad processor Intel Xeon. As an additional query, is there another source for Tkinter and ttk? Thanks in advance, Bill
