Pyqt Lineedit Is Empty When Called From Another Script

This is my mainscript which calls some generated UI and defines a few functions: import uifile from PyQt5 import QtWidgets import sys class App(QtWidgets.QMainWindow, uifile.Ui_M

Solution 1:

EDIT:

On second thoughts, the right approach depends on how mainscript is used. If it is used as the start-up script, it will not be initially imported, which then complicates things when it comes to accessing its globals later on.

A better approach is to have a very simple start-up script that only has this in it:

# mainscriptif __name__ == '__main__':
    from mainmodule import main
    main()

The mainmodule would then look like this:

# mainmoduleimport sys
from PyQt5 import QtWidgets
import uifile

classApp(QtWidgets.QMainWindow, uifile.Ui_MyWindow):
    def__init__(self):
        super().__init__()
        self.setupUi(self)
        self.btn_clickMe.clicked.connect(self.some_function)
    defsome_function(self):
        import othermodule
        othermodule.print_user()
    definput_user(self):
        user = self.lineEdit_username.text()
        return user

form = Nonedefmain_window():
    return form

defmain():
    global form
    app = QtWidgets.QApplication(sys.argv)
    form = App()
    form.show()
    app.exec_()

And othermodule would look like this:

# othermoduleimport mainmodule

defprint_user():
    print("user input: " + mainmodule.main_window().input_user())
