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

If you simply run your application script with an installation of Python and Tcl/Tk on the Mac, you will get whatever default application icon is defined for Python (or ActivePython, in this case). Using py2app means that you will bundle the Python and Tcl/Tk frameworks into a standalone app bundle (ActivePython and ActiveTcl can be used this way) and they can run on other systems without AP and AT being installed. And you can define your own icon. --Kevin -- Kevin Walzer Code by Kevin http://www.codebykevin.com

How do I control the application details on OSX?
by Bill Kidder Feb. 20, 2011

Feb. 20, 2011

Hi I'm using ActivePython 3.1, Active Tcl 8.5, and have built a simple app using tkinter. The application's icon is the ActivePython icon, not the one I set (this is a port of a Windows/Linux app, where the icon shows up), and the Application Menu has a label of "ActivePython 3.1" -- How do I get my icon to show up in the dock and the icon list when I do Command-Tab, and how can I change the instances of "Active Python 3.1" in the Application menu to my app's?

Hi. Is there any possibility to justify the text within a Text control?. In my example code, I set the text using the wrap option value 'word' Code:-------------------------------------------------------------- import Tkinter master = Tkinter.Tk() master.geometry('150x100') t = Tkinter.Text(master, wrap='word') t.pack(side='top', fill='both') master.mainloop() Thanks in advance.! Regards Cristian Abarzúa F. ----------------------- S.O: Ubuntu 9.10 Python 2.7 Gnome 2.28 Tkinter 8.5

Yes, you are right. Child threads must not control Tk and must communicate via share a thread communication mechanism. The following is my solution which works very well: import threading, time, socket from Tkinter import * EVENT = '<<EVENT>>' PORT = 12339 ADDR = ('', PORT) BUFSIZ = 1024 class Monitor(object): def __init__(self): self.s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) self.s.settimeout(0.0) # non-blocking self.s.bind(ADDR) self.run() def run(self): while True: try: data, addr = self.s.recvfrom(BUFSIZ) except socket.error, msg: break # I modified Tkinter.py slightly to support the 'data' key text.event_generate(EVENT, data=data) root.after(500, self.run) # Reschedule def On_EVENT(*args): event = args[0] text.insert(END, event.data) try: # Handle Tk vertical scroll bar bug v = vbar.get()[1] except ValueError: v = 0.0 if not v < 0.95: # Support user review of history text.see(tk.END) text.see(END) root = Tk() #--------------------------------------- text = Text(root) vbar = Scrollbar(root, orient=VERTICAL) vbar['command'] = text.yview text['yscrollcommand'] = vbar.set #--------------------------------------- text.grid(column=0, row=0, sticky=NSEW) vbar.grid(column=1, row=0, sticky=NS) root.columnconfigure(0, weight=1) root.rowconfigure(0, weight=1) #--------------------------------------- text.bind(EVENT, On_EVENT) #--------------------------------------- worker = Monitor() #--------------------------------------- root.mainloop() Trevor
