How to place the text at the center of an Entry box in Tkinter?
When we design user interfaces, we commonly use Entry boxes to receive and display input data. Sometimes we would like to center the text in the Entry boxes to make them more visually appealing. In this article, we will discuss how to place text at the center of an Entry box in Tkinter.
Basic Entry Box
First, we will take a look at a basic, typical Entry box in Tkinter. Let’s consider the following code:
from tkinter import *
root = Tk()
root.geometry("400x400")
entry_box = Entry(root)
entry_box.pack(pady = 20)
root.mainloop()
This creates a simple window with an Entry box in the center. It is a plain Entry box with no text in it.
Placing Text At the Center
Now, let’s write code to place the text in the center of the Entry box:
from tkinter import *
root = Tk()
root.geometry("400x400")
entry_box = Entry(root, justify='center')
entry_box.pack(pady=20)
entry_box.insert(0, "This is centered")
root.mainloop()
We have added a line that specifies the justify
attribute to set the text to center. Then we use the insert()
method to place the text “This is centered” at the center of the Entry box.
Creating a Custom Entry Box
We can also create a custom Entry box that applies suitable styling and visual appeal to our project.
Here is an example of a customized Entry box, with text centered in the box:
from tkinter import *
root = Tk()
root.geometry("600x600")
frame = Frame(root, bg="white")
frame.place(relx=0.5, rely=0.2, relwidth=0.75, relheight=0.1, anchor='n')
entry = Entry(frame, font=('Arial', 14), justify='center')
entry.place(relwidth=0.65, relheight=1)
root.mainloop()
In this example, we create a frame widget, setting its’ background color to white. We position the frame such that its’ relative width is 75% of its’ parent widget, and the height is 10% of its’ parent widget. The relx
parameter is set to 0.5, making it align center horizontally to the parent widget.
Then we create the Entry
widget inside the frame. We set the font as ‘Arial’ and the font size as 14. The text alignment inside the entry box is set to center.
Conclusion
In conclusion, centering text in Tkinter Entry boxes can be achieved with simple modifications by adding or specifying certain parameters to these controls. We can apply styling to our Entry boxes and make them look in line with our project requirements. Hence, we have demonstrated the steps and sample codes to center text in Tkinter Entry boxes.
