If you start this Python script, it will look like this:Įnjoying this page? We offer live Python training courses covering the content of this site. Root.bind('', (lambda event, e=ents: fetch(e)))ī2 = tk.Button(root, text='Quit', command=root.quit) Row.pack(side=tk.TOP, fill=tk.X, padx=5, pady=5)Įnt.pack(side=tk.RIGHT, expand=tk.YES, fill=tk.X) Lab = tk.Label(row, width=15, text=field, anchor='w') import tkinter as tkįields = 'Last Name', 'First Name', 'Job', 'Country' We use a Python list to hold the Entry descriptions, which we include as labels into the application. The next example shows, how we can elegantly create lots of Entry field in a more Pythonic way. Tk.Button(master, text='Show', command=show_entry_fields).grid(row=3, Use delete(0, END) to delete all text in the widget. If two are given, the range from "first" to "last" will be deleted. If only one number is given, it deletes the character at index. The delete() method has the format delete(first, last=None). What about deleting the input of an Entry object, every time, we are showing the content in our function show_entry_fields()? No problem! We can use the delete method. The new version of our Python program gets the following two lines, which can be appended after the Entry definitions, i.e.
we fill in "Miller" or "Baker" as a last name, and "Jack" or "Jill" as a first name. Let's assume now that we want to start the Entry fields with default values, e.g. The complete application looks now like this: Text='Show', command=show_entry_fields).grid(row=3, So, every time this button is clicked, the content of the Entry fields will be printed on the terminal from which we had called the script. We bind the function show_entry_fields(), which is using the get() method on the Entry objects, to the Show button. We extend our little script by two buttons "Quit" and "Show". To put it in a nutshell: The get() method is what we are looking for. But how can our program access this data? How do we read the content of an Entry? Okay, we have created Entry fields, so that the user of our program can put in some data. The window created by the previous script looks like this: Tk.Label(master, text="Last Name").grid(row=1) Tk.Label(master, text="First Name").grid(row=0) One for entering a last name and one for the first name. The following simple example creates an application with two entry fields. The comma separated list of options can be empty. Like other widgets, it's possible to further influence the rendering of the widget by using options. "master" represents the parent window, where the entry widget should be placed. The syntax of an entry widget looks like this: An entry widget is also limited to single font. If you want to enter multiple lines of text, you have to use the text widget. The arrow keys can be used to move to the invisible parts of the string. This means that the string cannot be seen in its entirety. If the user enters a string, which is longer than the available display space of the widget, the content will be scrolled. This widget allows the user to enter a single line of text. text strings, from the user of an application. Entry widgets are the basic widgets of Tkinter used to get input, i.e.
