In this article we will see how we can set background color to the QColorDialog’s push button i.e its child push button. QColorDialog is the pop up type widget in the PyQt5 used for selecting and creating colors. Color dialog is a huge widget that consists of lots of child widgets so it become tough to set stylesheet to the color dialog as it is a complex widget, below is how the background color to the QColorDialog widget’s push-button looks like
In order to do this we have to set the stylesheet to the QColorDialog object with the help of setStyleSheet method, below is the style sheet code
QColorDialog QPushButton
{
background-color : lightgreen;
}
Below is the implementation
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 QColorDialog object dialog = QColorDialog(self) # setting custom colors dialog.setCustomColor(1, Qt.red) dialog.setCustomColor(2, Qt.green) dialog.setCustomColor(3, Qt.yellow) dialog.setCustomColor(4, Qt.blue) # creating label label = QLabel("Geeks for Geeks", self) label.setAlignment(Qt.AlignCenter) # making label multi line label.setWordWrap(True) # setting stylesheet of the label label.setStyleSheet("QLabel" "{" "border : 5px solid black;" "}") # getting the custom color color = dialog.customColor(4) # setting graphic effect to the label graphic = QGraphicsColorizeEffect(self) # setting color to the graphic graphic.setColor(color) # setting graphic to the label label.setGraphicsEffect(graphic) # adding label to the color dialog layout = dialog.layout() layout.addWidget(label) dialog.setLayout(layout) # setting style sheet to the color dialog's push button # adding background color dialog.setStyleSheet("QColorDialog QPushButton" "{" "background-color : lightgreen;" "}") print(dialog.children()) # executing the color dialog dialog.exec_() # deleting the main window self.deleteLater()# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
