ttk

I want to fill my entries when I click in a name of my Combobox without buttons like 'check' to show the values. How can i do that? import tkinter as tk from tkinter import ttk import csv root = tk.Tk() cb = ttk.Combobox(root,state='readonly') labName = ttk.Label(root,text='Names: ') labTel = ttk.Label(root,text='TelNum:') labCity = ttk.Label(root,text='City: ') entTel = ttk.Entry(root,state='readonly') entCity = ttk.Entry(root,state='readonly') with open('file.csv','r',newline='') as file: reader = csv.reader(file,delimiter='\t') cb.grid(row=0,column=1) labName.grid(row=0,column=0) labTel

With this code fragment, I would expect the label to have a background color red. def createWidgets(self): style = ttk.Style() style.configure("Red.TLabel", foreground="green", background="red") self.label1 = ttk.Label(textvariable=self.numberArray[0][0],style="Red.TLabel") self.label1.pack() I get the green foreground color but I can't change the background color. This is on OS X. I'm using ActiveState's tcl and python. The same problem occurs with Python 3.2 and 2.7 You'll sometimes try to change an option that is supposed to exist according to element options, but it will have no effect. As

I am trying to create a drop down calendar for a date entry. Below is a portion of my code: The drop down portion of it dosen't work and I can't seem to find the syntax for DateEntry() of ttk calendar anywhere to include the calendar widget option! #creating the frame from tkinter import * from tkcalendar import * root = Tk() f1=Frame(root,width=1500,height=100,relief=SUNKEN,bd=4,bg='light steel blue') f1.pack(side=TOP) f2=Frame(root,width=1500,height=550,relief=SUNKEN,bd=4,bg='white') f2.pack() f3=Frame(root,width=1600,height=100,relief=SUNKEN,bd=4,bg='white') f3.pack(side=BOTTOM) #Creating

Is there an on-value-change type of event for data input widgets like Entry, Text, Spinner, Checkbutton, Radiobutton? By on-value-change, I mean the ability to detect when the value of a widget has changed due to keyboard input or cut/delete/paste (and Text edit_undo/edit_redo) activity? I see no such event described in the Tkinter event documentation [1]. Is the proper technique to link Tkinter variables to widget values I want to monitor and use these variables' .trace_variable( 'w', ... ) methods to bind to value changes? This seems like the right approach, but I haven't seen a lot of trace

Could anyone advise how to retrieve and update a Label widget with the value from a Scale widget in Python? Currently it shows a very large real number. I have tried to type cast the value but this only works when I print to idle. I tried slider.get() but the label is blank. Also tried int(slider.get()) which works when I print to idle. from tkinter import * from tkinter import ttk root = Tk() root.title("Playing with Scales") mainframe = ttk.Frame(root, padding="24 24 24 24") mainframe.grid(column=0, row=0, sticky=(N, W, E, S)) slider = IntVar() ttk.Scale(mainframe, from_=0, to_=100, length

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
