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

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

Python 3.4.0 alpha 2 available
by Ned Deily Sept. 25, 2013

Sept. 25, 2013

I would like call your attention to the latest alpha release of Python 3.4.0 and a new batteries-included feature for OS X users. For 3.4.0.a2, the python.org 64-bit/32-bit installer now includes its own private version of Tcl/Tk 8.5.14 so it is no longer necessary to install a third-party version of Tcl/Tk 8.5 to workaround the problematic system versions shipped in OS X 10.6+. Unlike Pythons from previous installers, only this private version will be used by tkinter and IDLE. It will have no effect on or be affected by any other versions of Tcl/Tk installed on your system, such as ActivelTcl 8.5.x or Apple 8.5.x. Since this is a new feature and somewhat experimental, it may change prior to the official release of Python 3.4.0, planned for 2014-02. There will be other OS X installer-related changes coming. Please report any problems or issues you encounter to the Python bug tracker. Thanks! http://www.python.org/download/releases/3.4.0/ http://www.python.org/download/mac/tcltk/ http://bugs.python.org -- Ned Deily, nad(a)acm.org

PanedWindow placement of sash
by Vasilis Vlachoudis Sept. 19, 2013

Sept. 19, 2013

Hi all, I am trying to save on exit and restore on startup the placement of the sash in the PanedWindow, with a code like this from Tkinter import * tk = Tk() p = PanedWindow(tk, orient=HORIZONTAL, width=600) p.pack(expand=YES,fill=BOTH) f1 = Label(p, text="First", bg="Red") p.add(f1) f2 = Label(p, text="Second", bg="Green") p.add(f2) p.sash_place(0, 450, 0) # <----------------------- tk.mainloop() The sash_place command is ignored. I believe because the window is not created yet and the dimensions are zero. So if I place an p.update_idletasks() before the sash_place, it works. Is there a more CLEAN to achieve the task. Is it recommended to use the update_idletasks before the mainloop? Thanks in advance Vasilis

Hi All, Does anyone know about issues related to getting Tkinter interfaces working with a "screen reader" (these programs that speak interface text for the sight impaired). Mick
