PyQt5 QDateTimeEdit – 获取特殊日期时间文本
在这篇文章中,我们将看到如何获得QDateTimeEdit小组件的特殊日期时间文本。在setSpecialValueText方法的帮助下,QDateTimeEdit会在当前值等于最小日期时间时显示这个特殊的文本而不是日期时间值。
为了做到这一点,我们将使用QDateTimeEdit对象的specialValueText方法。
语法: datetimeedit.specialValueText()
参数: 它不需要参数
返回: 它返回字符串
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)
# minimum date time
min_dt = QDateTime(2020, 10, 10, 11, 30)
# setting minimum date time
datetimeedit.setMinimumDateTime(min_dt)
# text
text = "GfG Date Time"
# setting special text to the date time edit
datetimeedit.setSpecialValueText(text)
# 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 special text
value = datetimeedit.specialValueText()
# setting text to the label
label.setText("Special Text : " + 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 :
