PyQt4 get text from line edit into label on button push - iFunKtion - Feb-24-2017
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
RE: PyQt4 get text from line edit into label on button push - Raures - Feb-25-2017
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.
