PyQt5 QDateTimeEdit - 清除布局方向属性

在本文中，我们将看到如何删除/清除 QDateTimeEdit 小部件的选定布局方向。清除布局方向会将布局方向恢复为默认值。布局方向指定 QDateTime 的方向，默认情况下增加或减少日期时间的箭头按钮在右侧，尽管通过setLayoutDirection方法设置布局方向，它们可以出现在左侧。

为了做到这一点，我们将使用带有 QDateTimeEdit 对象的unsetLayoutDirection方法。

Syntax : datetimeedit.unsetLayoutDirection()

Argument : It takes no argument

Return : It returns None

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, 500, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for components
    def UiComponents(self):
  
        # creating a QDateTimeEdit widget
        datetimeedit = QDateTimeEdit(self)
  
        # setting geometry
        datetimeedit.setGeometry(100, 100, 150, 35)
  
        # setting layout direction
        datetimeedit.setLayoutDirection(1)
  
        # clearing layout direction
        datetimeedit.unsetLayoutDirection()
  
        # creating a label
        label = QLabel("GeeksforGeeks", self)
  
        # setting geometry to the label
        label.setGeometry(100, 160, 200, 60)
  
        # making label multi line
        label.setWordWrap(True)
  
        # getting layout direction
        value = datetimeedit.layoutDirection()
  
        # setting text to the label
        label.setText("Layout Direction " + str(value))
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
