PyQt5 QSpinBox – 获取掩码

在这篇文章中，我们将看到如何获得旋转框的掩码，掩码基本上是用来隐藏旋转框的，在蒙版的帮助下，虽然旋转框仍然存在，但用户将无法看到整个旋转框但上面会有面具。可以借助setMask方法将掩码设置为旋转框。

为了得到掩码，我们使用mask方法。

Syntax : spin_box.mask()

Argument : It takes no argument

Return : It returns QRegion object

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 spin box
        self.spin = QSpinBox(self)
  
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)
  
        # setting range to the spin box
        self.spin.setRange(0, 999999)
  
        # setting prefix to spin
        self.spin.setPrefix("Prefix ")
  
        # setting suffix to spin
        self.spin.setSuffix(" Suffix")
  
        # getting the region of children of spin box
        region = self.spin.childrenRegion()
  
        # setting mask
        self.spin.setMask(region)
  
        # creating label
        label = QLabel(self)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 200, 70)
  
        # making it multi line label
        label.setWordWrap(True)
  
        # getting mask
        mask = self.spin.mask()
  
        # setting to the label
        label.setText(str(mask))
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
window.spin.setFocus()
# start the app
sys.exit(App.exec())

输出 ：
