PyQt5 标签 - 检查标签是否为窗口类型

在本文中,我们将了解如何检查标签是否为窗口类型。窗口类型是告诉对象是否为窗口类型的属性。

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 label
        label = QLabel("Label", self)
  
        # setting alignment
        label.setAlignment(Qt.AlignCenter)
  
        # setting geometry to the label
        label.setGeometry(200, 100, 150, 60)
  
        # setting border
        label.setStyleSheet("border : 8px solid black;"
                            "background : white;")
  
  
        # checking if label is window type
        check = label.isWindowType()
  
        # making label
        result = QLabel(self)
  
        # setting geometry
        result.setGeometry(200, 200, 300, 30)
  
        # setting text
        result.setText("Window type ? : " + 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 :
