Python has various options for Graphical User Interface (GUI) development. One of the options is Tkinter. Tkinter and Python together provide a faster way for GUI development. The Tk GUI toolkit provides an object-oriented interface.
For creating GUI applications using Tkinter we have to follow a few steps –
- Import Tkinter module.
- Create the main window.
- Add various widgets to the GUI application as per requirements.
- Main event loop for every trigger by the user for performing specific actions.
Text widgets have advanced options for editing a text with multiple lines and format the display settings of that text example font, text color, background color. We can also use tabs and marks for locating and editing sections of data. We can also use images in the text and insert borders as well. And everything can be formatted as per the requirements.
