I am trying to make a simple gui for an AI assistant using PyQt5. In the gui I created a QPlainTextEdit to show the output of my Main program and created an QInputDialog to take user input. The output is working fine.
For the input I tried two things:
- First I tried to call the QInputDialog from the Main function (which is in another file), wherever input was needed I replace input() with userInput() (this function contains the QInputDialog). But importing the userInput function causes the MainWindow of GUI to run again, resulting in error.
- I created a button called "Input" to connect to the QInputDialog. This works fine, I click the "Input" button whenever written user input is required and the QInputDialog pops up. But I am unable to provide the returned value as input to the Main program.
Please let me know how can I return the QInputDialog value as input()
Here is the code
