Control position of Tkinter common dialogs?
by python＠bdurham.com Dec. 9, 2016

Python 2.7 under Windows: How can we control the position of Tkinter's common dialogs? Here's what we've discovered: * Certain common dialogs always open up relative to their parent window * Certain common dialogs always open up centered on the user's desktop * All common dialogs appear to ignore the optional parent= parameter Questions: * How can we force a dialog to open up relative to its parent window? * How can we force a dialog to open up centered on the user's desktop? Background: import tkColorChooser as colorchooser import tkFileDialog as filedialog import tkMessageBox as messagebox # always open up relative to parent windows fileOpen = filedialog.askopenfilename() fileOpens = filedialog.askopenfilenames() fileSaveAs = filedialog.asksaveasfilename() color = colorchooser.askcolor() # always open up centered on desktop folderOpen = filedialog.askdirectory() messagebox.askquestion() Malcolm

Frame button binding

Hi all, I want to create a Scrolled Frame, it works nicely with the place command however when I bind the B2-Motion, and I click the middle mouse button on the child buttons instead of dragging it does nothing, since they are capturing the B2 and not propagate it to the master. SimplifiedExample: def dragStart(e): print "B2-pressed") f = Frame(tk) f.pack(expand=YES, fill=BOTH) f.bind("<Button-2>", dragStart) Button(f, text="Button").pack() I found a not elegant solution of setting the bind to the toplevel like f.winfo_toplevel().bind("<Button-2>", dragStart) and in dragStart I am checking if not str(e.widget).startswith(str(f)): return Is there a better way of doing it? Thanks in advance Vasilis

Hi all, I have a window which I make full screen with the option tk = Tk() tk.attributes("-fullscreen", True) c = Canvas(tk, background="Black") c.pack(expand=YES, fill=BOTH, padx=0, pady=0) and displays a full screen "Black" canvas. despite I h ave padx=pady=0 I always get 1 pixel White frame all around. I believe that it comes from the toplevel window. How can I remove this frame or change its color to black Thanks in advance Vasilis

CMD in Tkinter (Python 3)

Hi all, I'm attempting to write an IDE for python, in python. My major problem is embedding a console on a tkinter frame so the IDE can run the user's script. I have browsed through many solutions, but they are mostly for Python 2 only (and no, converting them did not work). I looked at this: http://stackoverflow.com/questions/7253448/how-to-embed-a-terminal-in-a-tki… But xterm only works with Linux - is there a windows solution? Thanks, Hayden
