PyQt5 QCalendarWidget – 工具按钮的背景颜色

在本文中,我们将了解如何为 QCalendarWidget 的工具按钮设置背景颜色。工具按钮是顶部可用的按钮,即转到左右页面的按钮,为 QCalendarWidget 设置边框与为其他小部件设置背景颜色不同,日历是具有许多子部件的小部件,我们可以将背景颜色设置为独立组件也是如此。下面是工具按钮上带有背景颜色的日历的外观

为了做到这一点,我们将使用 QCalendarWidget 对象的setStyleSheet方法,下面是样式表代码

QCalendarWidget QToolButton
{
background-color : lightgreen;
}
QCalendarWidget QToolButton::hover
{
background-color : cyan;
}
QCalendarWidget QToolButton::pressed
{
background-color : red;
}

注意:我们使用 QToolButton::hover 和 QToolButton::pressed 仅在鼠标悬停在它们上方或被按下时添加边框,还有 !hover 和 !pressed 这与悬停和按下状态完全相反。

下面是实现

Python3
# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
  
# QCalendarWidget Class
class Calendar(QCalendarWidget):
  
    # constructor
    def __init__(self, parent = None):
        super(Calendar, self).__init__(parent)
  
  
  
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 QCalendarWidget object
        # as Calendar class inherits QCalendarWidget
        self.calendar = Calendar(self)
  
        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)
  
        # setting size of the calendar
        self.calendar.resize(350, 240)
  
        # move the calendar
        self.calendar.move(10, 10)
  
        # setting stylesheet
        # adding background color to the calendar's tool buttons
        # adding background color for hover and pressed state
        self.calendar.setStyleSheet("QCalendarWidget QToolButton"
                                    "{"
                                    "background-color : lightgreen;"
                                    "}"
                                    "QCalendarWidget QToolButton::hover"
                                    "{"
                                    "background-color : cyan;"
                                    "}"
                                    "QCalendarWidget QToolButton::pressed"
                                    "{"
                                    "background-color : red;"
                                    "}"
                                    )
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())


输出 :
