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

CJK input/python 3/ibus

Hi. I'm having issues using ibus and am trying to figure out where to go from here. This was on the ibus site where the ibus reply is essentially "not my problem": http://code.google.com/p/ibus/issues/detail?id=1391 I didn't find any mention on the python.org site Under Mint 14(Ubuntu 12.10)/python3.3/ibus1.4 I get core dumps when reseting ibus with focus in an entry widget. Under Mint 15(Ubuntu 13.04 I think)/python3.3/ibus1.5 the interface just doesn't change. I've attached the gdb output from the core file on the mint 14 machine. Where should I go from here??? Thank you Steve Smith

How to display the values of dictionary to tk window.
by Srinivas Rao Aug. 21, 2013

Aug. 21, 2013

This code is to receive and display the text on the tk window.But what i want to achieve here is: When the character is sent from master to slave. Receive the character on the slave, look up the character in the dict, display the value that corresponds to the key. I tried but couldn't succeed, can any one help me with the correct code. for example: when slave received a key called 'hw' from master,It has to display "hello world" on slave pc , when '0' received from master, should display "how are you?" on slave pc. thanks in advance. import serialimport threadingimport Queueimport Tkinter as tkfrom Tkinter import *import timeimport sys class SerialThread(threading.Thread): def __init__(self, queue): threading.Thread.__init__(self) self.queue = queue def run(self): s = serial.Serial('COM11',9600) while True: if s.inWaiting(): text = s.readline(s.inWaiting()) self.queue.put(text) class App(tk.Tk): def __init__(self): tk.Tk.__init__(self) self.geometry("1360x750") self.time = '' self.clock = tk.Label(self, font=('times', 50, 'bold'), fg='black', bg='yellow') self.clock.pack(side='bottom', anchor='se') frameLabel = tk.Frame(self, padx=10, pady =50) self.text = tk.Text(frameLabel, wrap='word', bg=self.cget('bg'), relief='flat') frameLabel.pack() self.text.pack() self.queue = Queue.Queue() thread = SerialThread(self.queue) thread.start() self.process_serial() self.msgs = { 'hw':"hello world", 'wpp':"welcome to python programming", 'h':"hello", 0:"how are you?", 1:"bye....", 'egm': "english general message how are you", 'egm2':"If the world is flat be carefull not to fall off" } def process_serial(self): self.time = time.strftime('%H:%M:%S') self.clock.config(text=self.time) firstitem = True while self.queue.qsize(): try: new = self.queue.get() size = sys.getsizeof(new) if size<40: self.text.config(font='TimesNewRoman 100') elif size>=40 and size<70: self.text.config(font='TimesNewRoman 75') else: self.text.config(font='TimesNewRoman 50') if firstitem: self.text.delete(1.0, 'end') firstitem = False self.text.tag_configure("tag-center", justify='center') #self.text.tag_add("center", 1.0, "end") self.text.insert('end', my_dictionary.setdefault(signal, 'wrong signal')) #self.text.insert('end', new, 'tag-center') except Queue.Empty: pass self.after(1000, self.process_serial) app = App() app.mainloop()

HI I have a question regarding tkFileDialog. Is there any way I can create the dialog with customised dimensions as the default is very small? Regards Paul Malherbe
