问题描述
使用 Kubuntu 18.04 (qt5 5.9.5),Python 3.6.我无法使用此代码来显示托盘图标;其他图标(如 Dropbox 等)也会显示,但不会显示:
Using Kubuntu 18.04 (qt5 5.9.5), Python 3.6. I can't get this code to show the tray icon; other icons like Dropbox, etc. are shown, but this not:
import sys
from PyQt5.QtWidgets import QApplication, QMenu, QSystemTrayIcon, qApp, QMessageBox
from PyQt5.QtGui import QIcon
def run_something():
print("Running something...")
if __name__ == '__main__':
print("Creating application...")
app = QApplication(sys.argv)
print("Creating menu...")
menu = QMenu()
checkAction = menu.addAction("Check Now")
checkAction.triggered.connect(run_something)
quitAction = menu.addAction("Quit")
quitAction.triggered.connect(qApp.quit)
print("Creating icon...")
icon = QIcon.fromTheme("system-help")
print("Creating tray...")
trayIcon = QSystemTrayIcon(icon, app)
trayIcon.setContextMenu(menu)
print("Showing tray...")
trayIcon.show()
trayIcon.setToolTip("unko!")
trayIcon.showMessage("hoge", "moge")
print("Running application...")
sys.exit(app.exec_())
显示了消息(hoge"、moge"),但我在任何地方都找不到图标......左上角都没有,如 其他帖子说.
The message ("hoge", "moge") is shown, but I can't find the icon anywhere... Neither in the left upper corner, as other post says.
推荐答案
不知道为什么,但是这段代码有效,sing PySide2(基本上和上面的代码是一样的...):
No idea why, but this code works, sing PySide2 (basically is the same code than above...):
import logging
import sys
from PySide2.QtGui import QIcon
from PySide2.QtWidgets import QSystemTrayIcon, QMenu, QApplication, QAction, QMessageBox
def run_something():
print("Running something...")
def show_message():
msg = QMessageBox()
msg.setIcon(QMessageBox.Information)
msg.setWindowTitle("MessageBox demo")
msg.setText("This is a message box")
msg.setInformativeText("This is additional information")
msg.setDetailedText("The details are as follows:")
msg.setStandardButtons(QMessageBox.Ok | QMessageBox.Cancel)
msg.exec_()
def show_tray_message(tray: QSystemTrayIcon):
tray.showMessage("Hoooo", "Message from tray")
if __name__ == '__main__':
app = QApplication([])
app.setQuitOnLastWindowClosed(False)
tray = QSystemTrayIcon(QIcon("acorn.png"), app)
menu = QMenu()
action_test = QAction("Show a message box")
action_test.triggered.connect(show_message)
menu.addAction(action_test)
action_tray_message = QAction("Show a message from tray")
action_tray_message.triggered.connect(lambda: show_tray_message(tray))
menu.addAction(action_tray_message)
action_exit = QAction("Exit")
action_exit.triggered.connect(app.exit)
menu.addAction(action_exit)
tray.setContextMenu(menu)
tray.setToolTip("Tool tip")
tray.show()
sys.exit(app.exec_())
