PyQt5 QDateTimeEdit – 设置当前部分
在这篇文章中,我们将看到如何在QDateTimeEdit小组件中以编程方式设置当前部分。在QDateTimeedit小组件中有许多部分,如年、月、小时、分钟部分。用户可以用鼠标或键盘选择任何部分,并对当前部分进行增量和减量操作。
为了达到这个目的,我们将使用QDateTimeEdit对象的setCurrentSection方法。
语法: datetimeedit.setCurrentSection(section)
参数: 它接受section对象作为参数
返回: 它返回无。
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, 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())
