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。
In order to do this we use isWindowType
method
Syntax : label.isWindowType()
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 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 :
