PyQt5 - 试管进度条

在本文中，我们将看到如何创建试管形状的进度条。基本上试管形状的进度条是垂直的进度条，底部有圆边。下面是试管进度条的表示。

In order to to do this we have to do the following –

1. Changing the orientation of progress bar from horizontal to vertical
2. Creating round corners to the progress bar at the bottom
3. Creating round corner to bar of progress bar at bottom.

为了在进度条和进度条条上创建圆底，下面是样式表代码。

QProgressBar
{
border: 1px solid black;
border-bottom-right-radius: 15px;
border-bottom-left-radius: 15px;
}
QProgressBar::chunk 
{
border-bottom-right-radius: 14px;
border-bottom-left-radius: 14px;
background : lightgreen;
}      

下面是实现。

# 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(250, 90, 30, 200)
  
        # set value to progress bar
        bar.setValue(40)
  
        # setting alignment to center
        bar.setAlignment(Qt.AlignCenter)
  
        # setting orientation to vertical
        bar.setOrientation(QtCore.Qt.Vertical)
  
        # setting rounder border at the bottom
        # setting rounded border to the bottom of bar of progress bar
        # and color
        bar.setStyleSheet("QProgressBar"
                          "{"
                          "border : 1px solid black;"
                          "border-bottom-right-radius: 15px;"
                          "border-bottom-left-radius: 15px;"
                          "}"
                          "QProgressBar::chunk"
                          "{"                         
                            
                          "border-bottom-right-radius: 14px;"
                          "border-bottom-left-radius: 14px;"
                          "background : lightgreen"
                          "}"
                          )
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
