Question

Hello i try to write a desktop app with tkinter for typing speed test i search but i cant find my answer is the any way to check the value of user entry in Textbox while app is running ? i need to compare user entry with test text i try to put the function before main loop when i init class but its just check the entry one time and also i try to use window.after()

this is my full code and problem is running last function

def run_test():
    random_number = random.randint(1, 5)
    test = session.query(data).filter(database.Database.id == random_number).first()
    return test

Okay, so take this with a grain of salt because I can’t test this on CustomTkinter, but you should be able to bind an event to your textbox like so:

# call a method called 'on_type' whenever a key is released in the text area
self.type_area.bind('<KeyRelease>', self.on_type)

You can define a callback method to handle this event. Thanks to the binding above, the event parameter is passed to your callback automatically when the event is triggered

def on_type(self, event):
    print(event)  # do whatever you need to do

FYI: binding to '<KeyRelease>' avoids (some) issues with key repeat caused by held keys
