I have a tkcalendar and it's pre-defined widget for Calendar, DateEntry and am trying to get the User's selected date for DateEntry. Whereas there is provision to extract the selected date for the Calendar widget using "selection_get()" but nothing for DateEntry that I could find. I have tried get_date(),get(),_date(), cget(), ._selection() amongst many others but they don't seem to return/print the user-selected date. Please help, kindly let me know if any added information is needed Code [picked from a simple tkcalendar tutorial]: import tkinter as tk from tkinter import ttk from tkcalendar

Please see two edits below (added later)... I have loaded a big data.frame into memory ( 2.7 mio rows and 7 columns - 74 MB of RAM ). If I want to view the data using Tcl/Tk's Tktable widget via the tcltk2 package function tk2edit it takes over 15 minutes till the window is displayed with the data and about 7 GB of RAM (!) is consumed by R (incl. Tcl/Tk) en plus! Example: library(tcltk2) my.data.frame <- data.frame(ID=1:2600000, col1=rep(LETTERS,100000), col2=rep(letters,1E5), col3=26E5:1) # about 40 MB of data tk2edit(my.data.frame) The basic problem seems to be that each cell of the data

I want to do simple graphing routines in Tcl/Tk like scatter plot, x-y plot, histograms. I am using Tcl/Tk 8.5.7. I found in Tcler's wiki that there are few options such as BLT which is not supported in Tcl/Tk 8.5+ Is there any Tcl/Tk interface to gnuplot or any widget to accomplish graphing? Please let me know about the choices for graphing routines in Tcl/Tk. Gnuplot can indeed produce output that Tcl/Tk can consume. This page on the Tcler's Wiki describes how (though with some extra complexity because it is doing animations). Here's a simplified version: package require Tk eval [exec

Given below is the code for creating independent windows using Tkinter and Python: import Tkinter Tkinter.NoDefaultRoot() win1=Tkinter.Tk() win2=Tkinter.Tk() Tkinter.Button(win1, text='Woho!',command=win1.destroy()).pack() Tkinter.Button(win2, text='Woho!',command=win2.destroy()).pack() win1.mainloop() On execution it displays: Traceback (most recent call last): File "C:\Users\Administrator\Desktop\eclipse\Python Projects\Project 1\Source1\mod.py", line 8, in <module> Tkinter.Button(win1, text='Woho!',command=win1.destroy()).pack() File "C:\Python27\lib\lib-tk\Tkinter.py", line 2106, in __init

I regularly find myself writing Tk dialog boxes using ttk::entry widgets to prompt for a filename. I save the user's last input to such a dialog and display it as the default when next displaying it. After I've populated the widget, if the full filename is longer than the entry box, then it will display the leftmost few characters which are generally the less interesting part of the filename and I'd rather it displayed the rightmost characters. I found that attempting to use $entryWidget xview immediately didn't work very well - it did nothing, which I assume was because of some race condition

Hi i get an error with this code that StringVar() is not defined, and its probably a small thing but i am not that experienced with tkinter and would like some help, thanks. Here's my code: import tkinter as tk class Converter1(tk.Tk): def __init__(self): tk.Tk.__init__(self) self.entry = tk.Entry(self) self.variable = StringVar() self.variable.set("Miles to Kilometers") # default dropdown menu value self.menu = tk.OptionMenu(self, variable, "Miles to Kilometers", "Kilometers to Miles") self.button = tk.Button(self, text="Convert!", command=self.convertMK) self.button.pack() self.menu.pack()

I'm using Python 2.7.4 and new to Tkinter, and I'm stuck with the following code. I generated an event "test" and set the "data" option with a string, but an error occurred when retrieving it from event. Error -> AttributeError: Event instance has no attribute 'data' from Tkinter import * def handle_it(event): # print "event handler" print event.data root = Tk() root.after(1, lambda: root.event_generate('<<test>>', data="hi there")) root.bind('<<test>>', handle_it) root.mainloop() I can't find the related Python docs for this case, so I referred to the tcl document as below http://www.tcl.tk
