PyQt4 get text from line edit into label on button push

[iFunKtion]

I am trying to design data input form that will add text to a label when the text is entered into a line edit widget when the ok button is pressed, but the answer is completely eluding me:

#!/usr/bin/python3
#-*- coding: utf-8 -*-

"""
Set label text from line edit with 
ok click
"""

import sys
from PyQt4 import QtGui, QtCore


class Example(QtGui.QMainWindow):

    def __init__(self):
        super(Example, self).__init__()

        self.initUI()

    def initUI(self):

        self.qle = QtGui.QLineEdit(self)
        self.qle.move(100, 0)
        
        global sometext
        sometext = self.qle.text              # <---- This line I think is the problem

        self.lbl = QtGui.QLabel(self)
        self.lbl.move(100, 100)
        btn = QtGui.QPushButton("Ok", self)
        btn.move(30, 100)

        btn.clicked.connect(self.buttonClicked)

        self.setGeometry(200, 200, 300, 200)
        self.show

    def buttonClicked(self, sometext):
        sender = self.sender()
        self.lbl.setText(sometext)

def main():

    app = QtGui.QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

How do I make this work please

You could simply call QLineEdit's .text() method. Solution below.

#!/usr/bin/python3
#-*- coding: utf-8 -*-

"""
Set label text from line edit with 
ok click
"""

import sys
from PyQt4 import QtGui, QtCore


class Example(QtGui.QMainWindow):

    def __init__(self):
        super(Example, self).__init__()

        self.initUI()

    def initUI(self):

        self.qle = QtGui.QLineEdit(self)
        self.qle.move(5, 5) # re
        
        global sometext
        sometext = self.qle.text              # <---- This line I think is the problem

        self.lbl = QtGui.QLabel(self)
        self.lbl.move(5, 55)
        btn = QtGui.QPushButton("Ok", self)
        btn.move(5, 30)

        btn.clicked.connect(self.buttonClicked)

        self.setGeometry(200, 200, 300, 200)
        self.show()

    def buttonClicked(self, sometext):
        sender = self.sender()
        self.lbl.setText(self.qle.text()) # calling .text() method to
                                            # get the text from QLineEdit
def main():

    app = QtGui.QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

Thank you, it was so simple I didn't think to try it.
