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。
Syntax : font.strikeOut()
Argument : It takes no argument
Return : It returns bool
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 :
