PyQt5 QDial – 获取 Notch 可见属性

在本文中,我们将看到如何获得 QDial 的缺口可见属性,默认情况下,QDial 的缺口是禁用的,尽管我们可以随时借助setNotchesVisible方法使其可见。缺口基本上是围绕表盘绘制的一系列缺口,以指示可用值的范围。

为了做到这一点,我们使用带有 QDial 对象的notchesVisible方法

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, 500, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for components
    def UiComponents(self):
  
        # creating QDial object
        dial = QDial(self)
  
        # setting geometry to the dial
        dial.setGeometry(100, 100, 100, 100)
  
        # making notch visible
        dial.setNotchesVisible(True)
  
        # creating a label
        label = QLabel("GeeksforGeeks", self)
  
        # setting geometry to the label
        label.setGeometry(220, 125, 200, 60)
  
        # making label multiline
        label.setWordWrap(True)
  
        # getting notch visible property
        value = dial.notchesVisible()
  
        # setting text to the label
        label.setText("Notch Visible : " + str(value))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
