如何实例化qsystemtrayicon

Question

如何修复以下错误？

from PyQt5 import Qt
import sys
app = Qt.QApplication(sys.argv)
systemtray_icon = Qt.QSystemTrayIcon(app,    
Qt.QIcon(r'C:UserspsivabalDesktopo-SWAMI-VIVEKANANDA-facebook.jpg'))
systemtray_icon.show()
systemtray_icon.showMessage('Title', 'Content')

错误：

Traceback (most recent call last):
  File "C:/Users/psivabal/Desktop/Udacity/My_Examples/Cricket Score trying/TRial.py", line 4, in <module>
    systemtray_icon = Qt.QSystemTrayIcon(app, Qt.QIcon(r'C:UserspsivabalDesktopo-SWAMI-VIVEKANANDA-facebook.jpg'))
TypeError: arguments did not match any overloaded call:
  QSystemTrayIcon(parent: QObject = None): too many arguments
  QSystemTrayIcon(QIcon, parent: QObject = None): argument 1 has unexpected type 'QApplication'

Answer 1

根据文档，您应该实例化qsystemtrayicon如下：

Qt.QSystemTrayIcon(Qt.QIcon(r'icon.jpg'), app)

提示：qObject是在图标实例
