PyQt5 QSpinBox - 检查文本是否删除

在本文中,我们将看到如何检查旋转框的文本是否被删除。 Strike out/through 是单词的印刷表示,其中一条水平线穿过它们的中心,从而产生这样的文本。与经过审查或净化的文本相反,这些文字仍然可读。此演示文稿表示两种含义之一。我们可以借助setStrikeOut方法使旋转框的文本删除。

为了做到这一点,我们使用带有旋转框的 QFont 对象的strikeOut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, 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 font of the spin box
        font = self.spin.font()
  
        # setting strike out
        font.setStrikeOut(True)
  
        # reassigning this font to the spin box
        self.spin.setFont(font)
  
        # creating a label
        label = QLabel(self)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 60)
  
        # checking if text is strike out
        check = font.strikeOut()
  
        # setting text to the label
        label.setText("Strike Out ? : " + str(check))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
