Hello Mister. In Customtkinter is there any chance I can show a help text box when I hover over a label or entry? I'm referring to those little white boxes that show information.

How to create shapes e.g. Arrows and act on it (called event in C++ Builder) when touched. I use a RSPi and Python and like to control an output pin with touching the arrow.

One super annoying thing about the CTkComboBox widget is that if the list of values is pretty big, instead of popping open a small dropdown with a scroll bar it just fills the entire height of your screen and puts arrow buttons at the top and bottom. Extremely inconvenient for what I need it for, and I'm not sure if there's a way to change it to being able to use the scroll wheel. That's why I came here, to see if that was an option. Also, I'm not sure what I'm doing wrong but I can't programmatically change what the combo box is set to the same way shown because using the set method raises an AttributeError.

Hello! thank you for doing this set of tutorials it's been a great help! I'm getting an error with the comboBox tho, (object has no attribute "configure") do you have any idea of what that could be? cheers and again thanks for the work!

[@sergioduque4123]

My mistake! I was doing my_combo = customtkinter.CTkComboBox().place() and my variable was getting the place atts as well, giving the error

[@hendrikd5544]

Hello! Thanks for all these great videos, they help me a lot! I just wanted to ask, if it's possbile to have a scrollable box of the displayed options in the combobox. In my use case there are way too many options and therefore they fill the whole screen. Thanks in advance!

[@Codemycom]

Hm, not sure...try putting your combobox in a scrollable frame and see how it goes

[@xvekii3236]

Hey, did you solve your problem?

[@sovereignlivingsoul]

if you were to disable the button, how would you suppress the error output, thanks for the Tkinter book, looking forward to a long read

[@TkinterPython]

what do you mean?

[@sovereignlivingsoul]

@@TkinterPython at 20:59, you disable the input button and then you pressed the pick yellow button and the error output went to the screen, if you wanted to disable the button, could you redirect the error output

[@TkinterPython]

Sure probably@@sovereignlivingsoul

[@TSPxEclipse]

Put it in a try-except block. Just be sure that you specify the exact errors you want to bypass in the except clause or else you could be ignoring errors that completely break the program.

How to make 2 interlinked comboboxes where list of options in second combobox is based on selection from first combobox

[@TSPxEclipse]

Get the string for the selected option and pass it into a function that picks the list of values to be used for the next combo box in the sequence. That's how I'd do it, anyway.

[@robvanbakkum2029]

Great tutorials. Everything has been going well with Ctk so far... but I'm really stuck with the combo box... Is this just me or Mr. Schimansky? Please try before you answer.

[@TkinterPython]

Well I have no idea what problem you're having, so I couldn't possibly say...except to say I've had no problems with it, as evidenced in this video.

[@robvanbakkum2029]

Thanks for the quick response. pip uninstall and pip install solves the problem.
