问题 I'm trying to use Tkinter's Entry widget. I can't get it to do something very basic: return the entered value. Does anyone have any idea why such a simple script would not return anything? I've tried tons of combinations and looked at different ideas. This script runs but does not print the entry: from Tkinter import * root = Tk() E1 = Entry(root) E1.pack() entry = E1.get() root.mainloop() print "Entered text:", entry Seems so simple. Edit: In case anyone else comes across this problem and

问题 I noticed that the width argument for the Tkinter entry widget is in characters, not pixels. Is it possible to adjust the width in pixels? 回答1: You cannot specify the worth in pixels using the '-width' option, but there are ways to accomplish the same thing. For example, you could pack an entry in a frame that has no border, turn off geometry propagation, then set the width of the frame in pixels. 回答2: You can also use the Place geometry manager: entry.place(x=10, y=10, width=100) #width in

问题 I'm making a simple app just to practice python in which I want to write text as if it were Notepad. However, I can't make my entry bigger. I'm using tkinter for this. Does anybody know how to make the height of an entry bigger? I tried something like this: f = Frame() f.pack() e = Entry(f,textvariable=1,height=20) e.pack() I know this doesn't work because there isn't a property of "height". However, I see that there is a width property. 回答1: It sounds like you are looking for tkinter.Text,

问题 I am writing a program in python that will take in specific formats, a Phone number and dollar/cent values. How can I make tkinter have default value which is permanent, not deletable. For example (XXX)-XXX-XXXX? basically you can add an entry to the widget but the entry is defined the permanent value like when its empty it looks like (_ _ _)-___-____ when it has text it looks like (434)-332-1234 回答1: If I understand you correctly, you want some sort of template in which a user can type his

问题 I am making a GUI in Tkinter with Python 2.7. I have a frame with about 30 entry boxes among other things. I don't have access to the code right now, but is there a way to check if any or several of the boxes are empty so I can warn the user and ask them if they want to proceed? Is there a way to go through each of them with a 'for' loop and check the length of each entry. Or is there a command to check if any box is empty? 回答1: You can get the content of the entry using Tkinter.Entry.get
