Build A Text Editor Part 6 - Creating Bold and Italic Text - Python Tkinter GUI Tutorial #109

In this video we'll create a toolbar with buttons that allow us to make our text bold or italics.

To add bold and italics text to our text box, we'll need to first define a new font, and then add as tag to the text widget with that new font. We'll do this for both bold and italics.

We'll also need to write some logic to determine whether the text was already bold or italics, and if so...un-bold or un-italics it.

Thanks so much for these John!

To anyone reading this in the future, if you don't want your programs to throw an error if you hit the Bold or Italics buttons without selecting anything, put "if my_text.tag_ranges("sel"): and then indent the function. At the end you can put "else: print("there is no selected text"). I'm no expert so this might not be best practice, was just getting annoyed by the error haha

Thanks John, for always doing a great job. Honestly, I can't thank you enough

[vitaliiseryi]

Thank you, John! Your lessons are incredible and useful!

You should add a notification system to the Django blog. Something like YouTube notification so when someone adds a new blog post it will automatically alert to everyone the website

nice one i was acctually looking for a video that showed how to do this so thanks!

[fentonmsu]

wonderful, i used your examples but i see i can't get the control b and control i to work and also cannot do bold and italics at the same time?

[oliversampson]

hi john! everyrthings really good, only thing is i am around 6:00 and can't seem to get the bold buttons and the other ones to appear?

[nimishpatri]

These videos are great. They're really explanatory, and they provide a ton of information. I've just been having one problem with saving the formatting. When I save the file, it doesn't keep the formatting. I've tried changing the file type to a .doc file, but it still didn't work. How can I fix this?

[sanjayrajasreeraja]

Make a video on ttk styles in Tkinter please

[yaman]

hey the bold thing didnt work for me please help

[abramdaniels]

I can't open the file after I bold the text, it will either refuse to open or not show the bold.

[arunbeckham]

Hey John!! The code is great but the real thing is we can't change to italic after changing to bold for given text.

[noisexcorexnojo]

whenever i try to use sel.first and sel.last it gives me a name error saying 'sel' isn't defined, any idea why?

[codindentation]

Hi sir wonderful job done by you. But a single doubt that bold and italic button are not working with each other. Any solution

[stephenpalcic]

where did the 'current_tags' come from. I'm getting an error.

[MrBradyKelly]

Great lessons, thanks, but....In your 'bold_it' function you use a variable called 'current_tags', but I cannot find where this variable is declared or initialized.

[fabiodefalco]

hi Mr. John. when I insert bold tags in my text and save the file those tags are not saved. when I reopen the file the text is correct but without the bold tag. I wanted to ask if this is normal?

[nisargchaudhary]

Obviously, your content is Amazing!!
Can you please share this program ... I am still having that status bar issue and not able to find it.
Thank You so much for such videos

[tontsa]

But is it possible to have text which is bolded AND italics at the same time?
