PyQt5 QCommandLinkButton – Setting Background Color for Checked states
In this article we will see how we can set background color to the checkable QCommandLinkButton according to the checked states. Command link button is a special type of button it has qualities of both push button and the radio button. By default there is no extra background color to the command link button althoughwe can set custom background color to it any time. We can make the command link button checkable with the help of setCheckable method, there are basically two checked states one is checked i.e when it is in pressed state and other is the unchecked state i.e when it is in the release state. In order to do this we will set style sheet code to it for that we use setStyleSheet method with the command link button object, below is the stylesheet code
QCommandLinkButton::checked { background-color : lightgreen; } QCommandLinkButton::!checked { background-color : red; }
Below is the implementation
Python3
# 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 ) # making it checkable cl_button.setCheckable( True ) # setting geometry cl_button.setGeometry( 150 , 100 , 200 , 50 ) # setting style sheet # setting background color according to checkedstate cl_button.setStyleSheet("QCommandLinkButton::checked" "{" "border : 1px solid black;" "background - color : lightgreen;" "}" "QCommandLinkButton::! checked" "{" "border : 1px solid black;" "background - color : red;" "}") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
