PyQt5 textbox example
The example below creates a window with a textbox.
import sys
from PyQt5.QtWidgets import QMainWindow, QApplication, QWidget, QPushButton, QAction, QLineEdit, QMessageBox
from PyQt5.QtGui import QIcon
from PyQt5.QtCore import pyqtSlot
class App(QMainWindow):
def __init__(self):
super().__init__()
self.title = 'PyQt5 textbox - pythonspot.com'
self.left = 10
self.top = 10
self.width = 400
self.height = 140
self.initUI()
def initUI(self):
self.setWindowTitle(self.title)
self.setGeometry(self.left, self.top, self.width, self.height)
# Create textbox
self.textbox = QLineEdit(self)
self.textbox.move(20, 20)
self.textbox.resize(280,40)
# Create a button in the window
self.button = QPushButton('Show text', self)
self.button.move(20,80)
# connect button to function on_click
self.button.clicked.connect(self.on_click)
self.show()
@pyqtSlot()
def on_click(self):
textboxValue = self.textbox.text()
QMessageBox.question(self, 'Message - pythonspot.com', "You typed: " + textboxValue, QMessageBox.Ok, QMessageBox.Ok)
self.textbox.setText("")
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = App()
sys.exit(app.exec_())
