PyQt5 – 进度条的皮肤

在这篇文章中，我们将看到如何为进度条设置皮肤。皮肤基本上是一个背景图片，但它会根据进度条的大小进行自我调整。下面是带背景图片的进度条和带皮肤的进度条的表示。

为了做到这一点，我们必须改变进度条的CSS样式表代码，它与setStyleSheet方法一起使用，下面是样式表代码。

QProgressBar
{
border :1px solid black;
}
QProgressBar::chunk
{
border-image : url(skin.png);
}

以下是实施情况。

# 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())

输出 :
