QCommandLinkButton is a control widget that was introduced by Windows Vista. Its intended use is similar to that of a radio button in that it is used to choose between a set of mutually exclusive options. The appearance of it is generally similar to that of a flat push button, but it allows for a descriptive text in addition to the normal button text. By default it will also carry an arrow icon, indicating that pressing the control will open another window or page or do something. Below is how the command link button looks like
Example :
We will create a window having a label and the command link button and when the command link button pressed the counter will increment in the label
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 ):
# counter value
self .n = 0
# creating label
label = QLabel( "Counter" , self )
# setting label geometry
label.setGeometry( 100 , 100 , 100 , 40 )
# creating a command link button
cl_button = QCommandLinkButton( "Next" , self )
# setting geometry
cl_button.setGeometry( 200 , 100 , 200 , 40 )
# adding action to the button
cl_button.clicked.connect( lambda : increment( self .n))
# method for incrementing the counter
def increment(n):
# increment
self .n = n + 1
# setting text to the label
label.setText( str ( self .n))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
