In this article we will see how we can set gradient color to the progress bar. Below is how normal color progress bar looks like vs the gradient color progress bar looks like.
In order to do this we have to change the CSS style sheet, below is the code for style sheet.
QProgressBar::chunk
{
border : 1px solid black;
background: QLinearGradient( x1: 0, y1: 0,
x2: 1, y2: 0,
stop: 0 #000fff,
stop: 1 #ff000f );
}
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, 600, 400) # calling method self.UiComponents() # showing all the widgets self.show() # method for widgets def UiComponents(self): # creating progress bar bar = QProgressBar(self) # setting geometry to progress bar bar.setGeometry(200, 150, 200, 30) # set value to progress bar bar.setValue(30) # setting alignment to center bar.setAlignment(Qt.AlignCenter) # setting gradient color to progress bar bar.setStyleSheet("QProgressBar" "{" "border : 1px solid black;" "background: QLinearGradient( x1: 0, y1: 0, x2: 1, y2: 0, stop: 0 # 00ffff, stop: 1 # ff000f );" "}") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
