PyQt5 QCalendarWidget 插入QAction
在这篇文章中,我们将看到如何在QCalendarWidget中插入QAction。为了做到这一点,我们使用insertAction方法,这个方法将动作插入到日历的动作列表中,在给出的动作之前。如果before是None或者before对这个部件来说不是一个有效的动作,它就会添加这个动作。
为了做到这一点,我们将使用QCalendarWidget对象的insertAction方法。
语法 : calendar.insertAction(before, action)
参数: 它需要两个QAction对象作为参数,第一个是已经添加的QAction,第二个是将被插入到’before’QAction之前的QAction。
返回: 它返回无。
下面是实现方法

# QCalendarWidget Class
class Calendar(QCalendarWidget):
# constructor
def __init__(self, parent = None):
super(Calendar, self).__init__(parent)

super().__init__()
# setting title
self.setWindowTitle("Python ")
# setting geometry

def UiComponents(self):
# creating a QCalendarWidget object
# as Calendar class inherits QCalendarWidget
self.calendar = Calendar(self)
# setting geometry to the calendar
self.calendar.setGeometry(50, 10, 400, 250)
# setting cursor
self.calendar.setCursor(Qt.PointingHandCursor)
# creating a QAction objects
action1 = QAction("Geek", self)
action2 = QAction("Python", self)
# creating action list
action_list = [action1, action2]
# adding actions to calendar
self.calendar.addActions(action_list)
# 3 rd action
action_mid = QAction("BTech", self)
# inserting action in before second action
self.calendar.insertAction(action2, action_mid)
# creating label to show the properties
self.label = QLabel(self)
# setting geometry to the label
self.label.setGeometry(100, 280, 300, 100)
# making label multi line
self.label.setWordWrap(True)
# getting action of the calendar
value = self.calendar.actions()
# setting text to the label
self.label.setText("Actions : " + 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:
