如何使用QSystemTrayIcon区分左右键单击

Question

Problem

在MacOS上运行以下PyQt5代码时（Sierra 10.12.6）

self.tray_icon = QtWidgets.QSystemTrayIcon(QtGui.QIcon("icon/path"), self)
self.tray_icon.activated.connect(self.on_systray_activated)

[...]

def on_systray_activated(self, i_reason):
    logging.debug("entered on_systray_activated. i_reason = " + str(i_reason))

即使右键单击，我们也会获得activation reason QSystemTrayIcon::Trigger

在其他系统（例如XFCE）上，当用户右键单击时，我们会获得QSystemTrayIcon::Context

Answer 1

QApplication.mouseButtons方法可用于获取当前的state of the mouse buttons：

def on_systray_activated(self, i_reason):
    buttons = QtWidgets.qApp.mouseButtons()
    if buttons & QtCore.Qt.RightButton:
        logging.debug('on_systray_activated: right-button')
