Python Tkinter text editor with file dialogs
Write a Python program using Tkinter to build a text editor application that combines file open, save, and save as dialogs for editing text files.
Sample Solution:
Python Code:
Explanation:
In the exercise above -
- Import "tkinter" as "tk" and "filedialog" for creating GUI components and opening file dialogs.
- Define the "open_file()" function, which displays a file dialog using "filedialog.askopenfilename()" function. This dialog allows the user to select a text file to open. If a file is selected, it reads the file content and displays it in the Text widget. The status label shows the opened file path.
- Define the save_file() function, which saves the current Text widget content to the current file path. If there is no current file path, it calls the "save_as_file()" function to specify a new file path. The status label shows messages about file saving or errors.
- Define the "save_as_file()" function, which opens a file save dialog using "filedialog.asksaveasfilename()" function. This dialog allows the user to specify a file path for saving the text. If a file path is selected, it sets the current file path and calls the "save_file()" function to save the content.
- Create the main Tkinter window, set its title, and create a Text widget for editing text.
- Create a StringVar variable current_file to keep track of the currently opened or saved file.
- Create a menu bar with a "File" menu that contains options for opening, saving, saving as, and exiting the program.
- The main event loop, "root.mainloop()", starts the Tkinter application.
