PyQt5 - 检索复选框的标题

在本文中，我们将看到如何检索复选框的标题。当我们创建一个复选框时，我们可以选择为复选框设置标题，或者在 setText 的帮助下，我们可以设置或更改标题。
为了检索标题，我们将使用 text 方法。

Syntax : checkbox.text()
Argument : It takes no argument.
Return : It returns string.

下面是实现。

Python3

# 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 the check-box
        checkbox = QCheckBox('Geek ?', self)
 
        # setting geometry of check box
        checkbox.setGeometry(200, 150, 100, 30)
 
        # getting the caption
        caption = checkbox.text()
 
        # creating label to print the
        label = QLabel("caption of check box = " +
                                     caption, self)
 
        # adjusting the size of label
        label.adjustSize()
 
        # moving the label
        label.move(200, 200)
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出：
