In this article we will see how to set the skin to the bar of progress bar. Skin is basically a background image but it adjust it self to the size of bar of progress bar. Below is the representation of bar of progress bar with background image and bar of progress bar with skin.
In order to do this we have to change the CSS style sheet code of bar of progress bar which is used with the setStyleSheet method, below is the style sheet code.
QProgressBar
{
border :1px solid black;
}
QProgressBar::chunk
{
border-image : url(skin.png);
}
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 background color to window # self.setStyleSheet("background-color : yellow") # 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, 100, 200, 30) # setting the value value = 70 bar.setValue(value) # setting alignment to center bar.setAlignment(Qt.AlignCenter) # setting skin to bar to progress bar bar.setStyleSheet("QProgressBar " "{" "border : 1px solid black;" "}" "QProgressBar::chunk" "{" "border-image : url(skin.png);" "}" ) App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
