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

ttk.Notebook - how to bind to tab events (tab caption has focus or mouseover)
by python＠bdurham.com May 9, 2012

May 9, 2012

I'm using the ttk.Notebook widget. What object do I bind to capture events related to specific tabs? I would like to trap when a tab caption gets keyboard focus ('<FocusIn>') and when the mouse pointer is over a specific tab caption ('<Enter>'). I can trap mouse clicks on tabs (<Button-1>, <Button-3>), but I can't find a way to determine what tab a user clicked on in the case of a right click. Thank you, Malcolm

Is it possible to have a separator line extending both columns (something like columnspan=2). If I add two separators, the first one appears ok while the second appears like a dot. from Tkinter import * def showMenu(event=None): menu = Menu(tk,tearoff=0) menu.add_command(label="PLA") menu.add_command(label="XZP") menu.add_separator() menu.add_command(label="RPP") menu.add_command(label="WED") menu.add_separator() menu.add_command(label="SPH") menu.add_separator() menu.add_command(label="RCC") menu.add_command(label="XCC") menu.add_command(label="YCC") menu.add_command(label="ZCC") menu.add_command(label="TRC") menu.add_separator() menu.add_command(label="ARB") menu.add_command(label="TRX") menu.add_command(label="TRZ") menu.add_command(label="XYP") menu.add_command(label="YZP") menu.add_separator() menu.add_command(label="BOX") menu.add_command(label="RAW") menu.add_separator() menu.add_command(label="ELL") menu.add_separator() menu.add_command(label="REC") menu.add_command(label="XEC") menu.add_command(label="YEC") menu.add_command(label="ZEC") menu.add_separator() menu.add_separator() menu.add_command(label="QUA") menu.add_command(label="TRY") menu.entryconfigure(17,columnbreak=1) menu.tk_popup(tk.winfo_pointerx(), tk.winfo_pointery()) tk = Tk() tk.bind("<3>",showMenu) tk.mainloop() Vasilis ________________________________________ From: Vasilis Vlachoudis Sent: 03 November 2011 11:48 To: Michael Lange; tkinter-discuss(a)python.org Subject: RE: [Tkinter-discuss] Muti-column menu Thank you very much.

CX_freeze and Tkinter on Macosx with Python 2.7
by Michael O'Donnell Nov. 7, 2011

Nov. 7, 2011

Hi all, Has anyone had any luck getting CX_freeze to work with a Tkinter-based application on Macosx for Python 2.7? I tried, and firstly it tried looking for the tcl and tk libraries in the wrong places. And once I patched that problem, it tried to write these folders to the build folder, but using the same folder names as existing files (which i think are the dynamic load libraries for tcl and tk). If it worked for you without problem, that's enough for me. Let me know. Mick

about Tkinter delete
by Kristen Aw Nov. 7, 2011

Nov. 7, 2011

Hi all I don't understand why I get this error. I'm trying to delete the existing points, then redraw them after this bit of code to 'animate' my simulation. def update(self, point1, point2): # Deletes existing points if self.point1: self.w.delete(point1) self.master.update_idletasks() if self.point2: self.w.delete(point2) self.master.update_idletasks() #draw new point # . . . The error message that I get is: . . . in update self.w.delete(point1) File "C:\PYTHON26\LIB\LIB-TK\Tkinter.py", line 2181, in delete self.tk.call((self._w, 'delete') + args) TclError: invalid command name ".44593760"

Muti-column menu
by Vasilis Vlachoudis Nov. 3, 2011

Nov. 3, 2011

Hi All, in my application I have a submenu (appearing both on the menu bar and with right-click) that contains many entries ~30. But it has to be in one submenu since they are various types of geometrical bodies to insert. Is there a way to create a multi-column sub-menu in Tkinter? Thanks in advance Vasilis
