In this article you will learn how to interact with a textbox using PyQt4.
If you want to display text in a textbox (QLineEdit) you could use the setText() method.

The textbox example below changes the text if the button is pressed.
import sys from PyQt4.QtCore import pyqtSlot from PyQt4.QtGui import * # create our window app = QApplication(sys.argv) w = QWidget() w.setWindowTitle('Textbox example @pythonspot.com') # Create textbox textbox = QLineEdit(w) textbox.move(20, 20) textbox.resize(280,40) # Set window size. w.resize(320, 150) # Create a button in the window button = QPushButton('Click me', w) button.move(20,80) # Create the actions @pyqtSlot() def on_click(): textbox.setText("Button clicked.") # connect the signals to the slots button.clicked.connect(on_click) # Show the window and run the app w.show() app.exec_() |
The text field is created with the lines:
textbox = QLineEdit(w) textbox.move(20, 20) textbox.resize(280,40) |
The button (from screenshot) is made with:
button = QPushButton('Click me', w) |
We connect the button to the on_click function by:
# connect the signals to the slots button.clicked.connect(on_click) |
This function sets the textbox using setText().
