PyQt5 - 检查标签是否为多行

在本文中，我们将看到如何检查标签是否为多行，当我们创建标签并为其设置文本时，如果文本长度大于标签额外文本的长度，则不显示多行label 使额外的文本进入另一行。下面是正常和多行标签的表示形式

为了检查标签是否为多行，我们使用wordWrap方法。

Syntax : label.ordwWrap()

Argument : It 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
        label1 = QLabel(self)
  
        # setting geometry to the label
        label1.setGeometry(200, 150, 100, 50)
  
        # adding border to the label
        label1.setStyleSheet("border : 2px solid black;")
  
        # creating label
        label2 = QLabel("Multi label i.e With multi line", self)
  
        # setting geometry to the label
        label2.setGeometry(200, 250, 100, 50)
  
        # adding border to the label
        label2.setStyleSheet("border : 2px solid black;")
  
        # making it multi line
        label2.setWordWrap(True)
  
        # check
        check = label2.wordWrap()
  
        # checking if label2 is multi line or not
        if check:
            label1.setText("YESSS")
  
        else:
            label1.setText("NOO")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
window.show()
  
# start the app
sys.exit(App.exec())

输出：
