QLineEdit : It allows the user to enter and edit a single line of plain text with a useful collection of editing functions, including undo and redo, cut and paste, and drag and drop. It is the basic widget in PyQt5 to receive keyboard input, input can be text, numbers or even symbol as well. Below is how the line edit look like
Example :
We will create a line edit and a label and when user enter text in it and when enter key is pressed, the label will display the entered text.
Below is the implementation
# importing libraries from PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGui from PyQt5.QtGui import * from PyQt5.QtCore import * import sys class Window(QMainWindow): def __init__(self): super().__init__() # setting title self.setWindowTitle("Python ") # setting geometry self.setGeometry(100, 100, 500, 400) # calling method self.UiComponents() # showing all the widgets self.show() # method for components def UiComponents(self): # creating a QLineEdit object line_edit = QLineEdit("Lazyroar", self) # setting geometry line_edit.setGeometry(80, 80, 150, 40) # creating a label label = QLabel("GfG", self) # setting geometry to the label label.setGeometry(80, 150, 120, 60) # setting word wrap property of label label.setWordWrap(True) # adding action to the line edit when enter key is pressed line_edit.returnPressed.connect(lambda: do_action()) # method to do action def do_action(): # getting text from the line edit value = line_edit.text() # setting text to the label label.setText(value) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
