PyQt5 QDateEdit - 可设置的设置时间范围

在本文中，我们将了解如何为 QDateEdit 设置时间范围。有时需要设置时间范围，以便用户无法输入/存储超出时间范围的时间。我们可以借助setTime方法设置时间到日期编辑。可以借助setMinimumTime和setMaximumTime方法将最小和最大时间设置为日期编辑。

为了做到这一点，我们使用带有 QDateEdit 对象的setTimeRange方法

Syntax : date.setTimeRange(t1, t2)

Argument : It takes two QTime object as argument

Return : It returns None

编程需要懂一点英语

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 QDateEdit widget
        date = QDateEdit(self)
  
        # setting geometry of the date edit
        date.setGeometry(100, 100, 200, 40)
  
        # alignment
        a_flag = Qt.AlignCenter
  
        # setting alignment of date
        date.setAlignment(a_flag)
  
        # QTime object
        t1 = QTime(1, 30)
        t2 = QTime(5, 45)
  
        # setting minimum time
        date.setTimeRange(t1, t2)
  
        # creating a label
        label = QLabel("GeeksforGeeks", self)
  
        # setting geometry
        label.setGeometry(100, 150, 250, 60)
  
        # making label multiline
        label.setWordWrap(True)
  
        # getting time
        value1 = date.minimumTime()
        value2 = date.maximumTime()
  
  
        # setting text to the label
        label.setText("Min and Max Time : " + str(value1) + " " + str(value2))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
