PyQt5标签 – 检查标签是否为部件类型
在这篇文章中,我们将看到如何检查标签是否为widget类型。widget类型是告诉我们该对象是否是widget的属性。
为了达到这个目的,我们使用isWidgetType方法
语法: label.isWidgetType()
参数: 它不需要参数
返回: 它返回bool
下面是实现方法
# 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 widget type
check = label.isWidgetType()
# making label
result = QLabel(self)
# setting geometry
result.setGeometry(200, 200, 300, 30)
# setting text
result.setText("Widget 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 :
