PyQt5 QCalendarWidget 鼠标抓取器属性
在这篇文章中,我们将看到如何获得QCalendarWidget的鼠标抓取器属性。我们可以在mouseGrabber方法的帮助下访问鼠标抓取器属性,这个方法会返回当前正在抓取鼠标输入的日历或其子女。如果这个应用程序中没有任何小部件当前正在抓取鼠标,则返回无。我们可以在grabMouse方法的帮助下抓取鼠标。
为了做到这一点,我们将使用QCalendarWidget对象的mouseGrabber方法。
语法: calendar.mouseGrabber()
参数: 它不需要参数
返回: 它返回QWidget对象
下面是实现的过程
# 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, 650, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for components
def UiComponents(self):
# creating a QCalendarWidget object
self.calendar = QCalendarWidget(self)
# setting geometry to the calendar
self.calendar.setGeometry(50, 10, 400, 250)
# setting cursor
self.calendar.setCursor(Qt.PointingHandCursor)
# grabbing the keyboard for the calendar
self.calendar.grabKeyboard()
# creating label to show the properties
self.label = QLabel(self)
# setting geometry to the label
self.label.setGeometry(100, 280, 250, 60)
# making label multi line
self.label.setWordWrap(True)
# getting mouse grabber property
value = self.calendar.mouseGrabber()
# setting text to the label
self.label.setText("Calendar Mouse grabber : " + 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:
