How do I get my code to interact with the ui TextFields?
So I'm trying to make a program that calculates the unit weight of concrete cylinder specimens given two different weights and the temperature of water used to measure one of the weights, and I can't seem to get the data that I put in the textfields to variables in the code.
When I run the code, I get these errors in the console:
"Warning: Could not bind action: name 'volumeField_action' is not defined"
Then again for 'unitWeightField_action' and 'calculateButton_action'
Can someone please tell me what I'm doing wrong?
Thank you <3

When using the UI designer and load_view, you need you have all of your callbacks defined before you call load_view. That's why you are getting the binding warnings.
Just define your callback actions at the beginning.
Also... Actions don't return values. Try print if you want to test...
@Julian8941 did you also define action in UI file? If yes, these are not yet known when you load_view your UI
@JonB we cross.. In French "les grands esprits se rencontrent"
Great minds think alike.
