Create a GUI app with Tkinter - Step by Step Tutorial

#gui #tkinter #python
In this tutorial, we'll build a PDF-extracting program that fetches text from a user-selected file.
We'll create a graphic interface with Tkinter, manipulate PDF files with PyPDF2 and present the logo of our app with Pillow/PIL.
🛑 You may need to adjust "filetype" tp "filetypes" in line 24 🛑:
file = askopenfile(parent=root, mode='rb', title="Choose a file", filetypes=[("Pdf file", "*.pdf")])

FYI - CD means "change directory" ... "Current directory" sounds similar and also fits with the letters, but is not the origin of the name of this command.

This was practical, and it is so much easier to learn something when the examples are closer to my project. I think your teaching style is matching with me :D Subscribed. One thing I did miss, that you wrote a lot of parameter but never explained it what they do. (for eg: text_box.tag_add("center", 1.0, "end"))

incredibly helpful. made my first GUI... finally! Here are some of the problems I encountered and the solutions spelling and capitalization errors "filetype" needed to be "filetypes" text didn't show up at first because of row arrangement, fix: add "rowspan" into canvas size rowspan=3 means there are three rows numbered 0, 1 and 2 note: I didn't add canvas size at the bottom, but had a buffer row. when the text box wasn't present, it automatically arranged proportionally. I appreciate this being taught without a more complex editor like PyCharm or Jupyter. This helps understand what is really happening, not to mention package installation is a whole secondary problem when working in PyCharm and some other IDEs.
