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.

tkinter askdirectory print
by RagZ Feb. 19, 2008

Feb. 19, 2008

Hello, I'm writing an application with a browse button that opens up the "askdirectory" box to choose a directory. The problem is when the directory is chosen and the ok button is hit it prints the directory to the terminal (if it's open) and I would like it to print it to a ENTRY() that I have. For example: from Tkinter import * from tkFileDialog import askdirectory root = Tk() e1 = Entry(root) #<---------I would like the dir1 to print here def browser(): dir1 = askdirectory(parent=root, title="Select A Folder", mustexist=1) if len(dir1) > 0: print dir1 Button(root, text="Browse", command=browser) root.mainloop() So from this what I'm asking is how can I get dir1 to print to e1 (the entry box)? I'm new to Python and am taking the learn-as-I-code route but can't seem to figure this one out. It might be really easy but I just don't see it. Thanks for any help. - RagZ -- View this message in context: http://www.nabble.com/tkinter-askdirectory-print-tp15468402p15468402.html Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.

Determining size of a widget in grid?
by Peter Milliken Feb. 19, 2008

Feb. 19, 2008

I have an application which uses the grid layout manager. One of my widgets can grow (and shrink) in width as various events in the application occur. Is there anyway to determine the width of the widget in terms of the column width that the grid manager determines? i.e. the grid manager calculates a column width based on the widgets placed in it - I would like to determine if the "new" width of the widget (as it grows/shrinks) requires a columnspan value or not and if it does, then how many columns should it span? At the moment, as the width of the widget gets larger than the column size allocated in the "other" columns, it makes the widgets in the same column (but different rows) look untidy because that "column" is a different size to the others (the "other" widgets are of a uniform size - it is just this one widget that grows/shrinks that is out of play in the grid/table layout).

tk_focusNext and tkfocusPrev
by Hunter0000 Feb. 18, 2008

Feb. 18, 2008

Hello, Can anyone give an example of how to use these two methods? I've tried using them is various ways (the end goal being to replicate forward and reverse tabbing) but it always comes out saying either it doesn't exist or the object it returns in unsubscriptable. Any of the documentation I can find about most of the focus-related methods seems spotty at best, and in this case nonexistent, so an actual working example would be great to work from.
