Reliable position to pop context menus for tray icon on left click with Wayland

glgl-schemer

I got from the guidelines that I should not rely on QCursor::pos when I pop a menu on Wayland. But how could I get a reliable position when I click a tray icon by left click? I wrote a simple script with QSystemTrayIcon as below, but the member function geometry always returns a point at (0, 0) inside on_left_click. I also tried to override event and eventFilter to get a position from an event, but the functions were never called.

from PyQt6.QtGui import QAction, QCursor, QIcon
from PyQt6.QtWidgets import QApplication, QMenu, QSystemTrayIcon

class MyTray(QSystemTrayIcon):
  def __init__(self):
    super().__init__(QIcon.fromTheme('start-here'))
    self.activated.connect(lambda reason: self.on_left_click(reason))

  def on_left_click(self, reason):
    if reason == QSystemTrayIcon.ActivationReason.Trigger:
      self.contextMenu().popup(QCursor.pos()) # not accurate on Wayland

def main():
  app = QApplication([])
  app.setQuitOnLastWindowClosed(False)

  menu = QMenu()
  action = QAction()
  action.setText('Hello')
  menu.addAction(action)

  tray = MyTray()
  tray.setVisible(True)
  tray.setContextMenu(menu)
  app.exec()

if __name__ == '__main__':
  main()

I installed MyTray as the filter of QApplication, so MyTray is updated as follows:


class MyTray(QSystemTrayIcon):
  pos = None

  def __init__(self, app):
    super().__init__(QIcon.fromTheme('start-here'))
    self.activated.connect(lambda reason: self.on_left_click(reason))
    app.installEventFilter(self)

  def on_left_click(self, reason):
    if reason == QSystemTrayIcon.ActivationReason.Trigger:
      print('Clicked!!!')
      self.contextMenu().popup(self.pos if self.pos else QCursor.pos())

  def eventFilter(self, _, event):
    print(event)
    return False

And I got the following events:

Clicked!!!

It seems none of them can provide a position.

Hi,

I am unsure about what you are trying to achieve.

Did you take a look at the System Tray Icon example ? Does it do what you want ?

There is a restriction in Wayland in that the standard protocol that does allow positioning windows (see https://bugreports.qt.io/browse/QTBUG-110119 ).
