Python 3 – Tkinter Dimensions
Tkinter is a library in Python that is used to create graphic user interface(GUI) applications. It is a standard Python library that can be imported and used to create windows, buttons, menus, and other GUI elements.
When creating a GUI with Tkinter, it is essential to specify the dimensions of the elements correctly. Dimensions refer to the height and width of a widget or frame. This article will cover how to specify the dimensions of widgets in Tkinter using various methods.
Method 1: Using pack() Method
One way to specify dimensions of widgets in Tkinter is by using the pack() method. The pack() method is a geometry manager that arranges widgets in blocks before placing them in the parent widget. When calling the pack() method, you can specify the height and width of the widget using the ‘height’ and ‘width’ parameters.
from tkinter import *
root = Tk()
#Create a Label widget
lbl = Label(root, text="Hello World", bg="yellow", height=2, width=20)
lbl.pack()
root.mainloop()
Method 2: Using grid() Method
Another way to specify dimensions of widgets in Tkinter is by using the grid() method. The grid() method is a geometry manager that arranges widgets in a grid of rows and columns.
To specify the dimensions of the widgets using the grid method, you can use the ‘height’ and ‘width’ parameters.
from tkinter import *
root = Tk()
#Create a Label widget
lbl = Label(root, text="Hello World", bg="yellow")
lbl.grid(row=0, column=0, padx=20, pady=20, sticky=W+E)
root.mainloop()
Method 3: Using place() Method
The third way to specify dimensions of widgets in Tkinter is by using the place() method. The place() method is a geometry manager that places widgets at specific locations.
To specify the dimensions of the widgets using the place() method, you can use the ‘height’ and ‘width’ parameters.
from tkinter import *
root = Tk()
#Create a Label widget
lbl = Label(root, text="Hello World", bg="yellow", height=2, width=20)
lbl.place(x=50,y=50)
root.mainloop()
Method 4: Using configure() Method
You can also specify the dimensions of widgets in Tkinter after they have been created. This can be achieved using the configure() method. The configure() method allows you to modify the attributes of a widget after it has been created.
from tkinter import *
root = Tk()
#Create a Label widget
lbl = Label(root, text="Hello World", bg="yellow")
#Configure the Label widget
lbl.configure(width=20, height=2)
lbl.pack()
root.mainloop()
Conclusion
In conclusion, specifying dimensions of widgets in Tkinter is an essential aspect of creating a GUI application. This article has demonstrated four different methods you can use to specify dimensions of widgets in Tkinter. You can use either the pack(), grid(), or place() method to specify the dimensions during widget creation or use the configure() method to modify the dimensions after the widget is created. Keep in mind that specifying the dimensions correctly will improve the look and feel of your GUI application.
