In this article we will see how we can go to the next state of the checkable QCommandLinkButton. We can make the command link button checkable with the help of setCheckable
method, this will make two states of the command link button which will be checked i.e pressed and unchecked i.e released state. Next state will change the state according to the current state.
In order to do this we use nextCheckState
method with the command link button object
Syntax : button.nextCheckState()
Argument : It takes no argument
Return : It return None
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 )
# making button checkable
cl_button.setCheckable( True )
# creating a push button
push = QPushButton( "Next State" , self )
# setting geometry to the push button
push.setGeometry( 50 , 100 , 120 , 40 )
# adding action to the push button
push.clicked.connect( lambda : next_method())
# method called by push button
def next_method():
# going to next state
cl_button.nextCheckState()
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
