PyQt5 QDateEdit – 获取样式表

在本文中，我们将了解如何将样式表用于日期编辑。设置样式表使日期编辑看起来独一无二，借助样式表我们可以为日期编辑设置颜色、边框和许多其他内容。我们可以借助setStyleSheet方法设置样式表。

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

Syntax : date.styleSheet()

Argument : It takes no argument

Return : It returns string

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)
  
        # setting style sheet
        date.setStyleSheet("QDateEdit"
                           "{"
                           "border : 2px solid black;"
                           "background : white;"
                           "padding : 5px;"
                           "}"
                           "QDateEdit::up-arrow"
                           "{"
                           "border : 2px solid black;"
                           "background-color : lightgreen;"
                           "}"
                           "QDateEdit::down-arrow"
                           "{"
                           "border : 2px solid black;"
                           "background-color : red;"
                           "}"
                           )
  
        # creating a label
        label = QLabel("GeeksforGeeks", self)
  
        # setting geometry
        label.setGeometry(100, 150, 250, 60)
  
        # making label multiline
        label.setWordWrap(True)
  
        # getting style sheet
        value = date.styleSheet()
  
  
        # setting text to the label
        label.setText("Style Sheet : " + 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 ：
