In this article we will see how we can get the released signal of the QCommandLinkButton. This signal is emitted when the button is released. There are two stages when button is clicked first is the pressed state and second is the release state.
In order to do this we use released
method with the command link button object
Syntax : button.released.connect(method)
Argument : It takes method as argument
Action Performed : It calls the method when the clicked signal is emitted
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 command link button
cl_button = QCommandLinkButton( "Press" , self )
# setting geometry
cl_button.setGeometry( 250 , 100 , 200 , 50 )
# creating label
label = QLabel( "GeeksforGeeks" , self )
# setting label geometry
label.setGeometry( 100 , 100 , 200 , 40 )
# released signal
# set text to the label
cl_button.pressed.connect( lambda : label.setText( "Released Signal Emitted" ))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
