PyQt5 QDateTimeEdit – 设置当前部分
在本文中,我们将了解如何以编程方式在 QDateTimeEdit 小部件中设置当前部分。 QDateTimeedit 小部件中有许多部分,例如年、月、小时、分钟部分。用户可以借助鼠标或键盘选择任何部分,并对当前部分执行递增和递减操作。
为了做到这一点,我们将使用带有 QDateTimeEdit 对象的setCurrentSection
方法。
Syntax : datetimeedit.setCurrentSection(section)
Argument : It takes section object as 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)
# creating a push button
push = QPushButton("Press", self)
# setting geometry to the push button
push.setGeometry(120, 160, 120, 35)
# when push button get clicked connect to the method
push.clicked.connect(lambda: push_method())
def push_method():
# set the current section
datetimeedit.setCurrentSection(QDateTimeEdit.MonthSection)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
