模拟用户单击QSystemTrayIcon [英] Simulate user clicking in QSystemTrayIcon

问题描述

即使通过activated插槽正在执行，菜单仍未显示.我通过手动单击托盘图标和模拟单击来跟踪，并通过相同的执行逻辑进行跟踪.

Even through the activated slot is being executed, the menu is still not showing. I traced through manually clicking the tray icon and the simulated click, and its going through the same execution logic.

目前我有

class MyClass(QObject):
   def __init__():
       self._testSignal.connect(self._test_show)
       self.myTrayIcon.activated.connect(lambda reason: self._update_menu_and_show(reason))

   def show():
       self._testSignal.emit()

   @pyqtSlot()
   def _test_show():
       self._trayIcon.activated.emit(QtWidgets.QSystemTrayIcon.Trigger)

   @QtCore.pyqtSlot()
   def _update_menu_and_show(reason):
       if reason in (QtWidgets.QSystemTrayIcon.Trigger):
        mySystemTrayIcon._update_menu()

...
class MySystemTrayIcon(QSystemTrayIcon):

   def _update_menu(self):
      # logic to populate menu
      self.setContextMenu(menu)
...
MyClass().show()

推荐答案

下面是我弹出与托盘图标关联的上下文菜单的方式

Here is how I made the context menu associated with the tray icon pop up

class MyClass(QObject):
   def __init__():
       self._testSignal.connect(self._test_show)
       self.myTrayIcon.activated.connect(lambda reason: self._update_menu_and_show(reason))

   def show():
       self._testSignal.emit()

   @pyqtSlot()
   def _test_show():
       self._trayIcon.activated.emit(QSystemTrayIcon.Context)

   @QtCore.pyqtSlot()
   def _update_menu_and_show(reason):
       if reason in (QSystemTrayIcon.Trigger, QSystemTrayIcon.Context):
           mySystemTrayIcon._update_menu()
           # Trigger means user initiated, Context used for simulated
           # if simulated seems like we have to tell the window to explicitly show

           if reason == QSystemTrayIcon.Context:
               mySystemTrayIcon.contextMenu().setWindowFlags(QtCore.Qt.WindowStaysOnTopHint|QtCore.Qt.FramelessWindowHint)
               pos = mySystemTrayIcon.geometry().bottomLeft()
               mySystemTrayIcon.contextMenu().move(pos)
               mySystemTrayIcon.contextMenu().show()

...
class MySystemTrayIcon(QSystemTrayIcon):

   def _update_menu(self):
      # logic to populate menu
      self.setContextMenu(menu)
...
MyClass().show()

似乎您必须在上下文菜单上设置WindowStaysOnTopHint，以便它出现. 此解决方案特定于mac，因为它假定任务栏位于顶部.

It seems you have to set the WindowStaysOnTopHint on the context menu so that it will appear. This solution is specific to mac since it assumes the taskbar is on the top.

一个副作用是，即使用户单击其他位置，上下文菜单也始终位于顶部.我在上下文菜单上放置了一个事件过滤器，它注册的唯一有用的事件是QEvent.Leave

One side effect is that the context menu is always on top, even if the user clicks somewhere else. I placed an event filter on the context menu, the only useful event that it registered was QEvent.Leave
