通过任务计划程序执行时，如何为Qt应用加载任务栏图标？

Question

我有一个带有qt designer ui的python应用程序，我使用pyinstaller将.py转换为exe，托盘图标在手动执行时有效，但是一旦我尝试使用任务计划程序运行它，该应用程序就会运行，但是我没有任何图标。我已附上两张显示这两种情况的图像

手动运行时会发生什么

由任务计划程序运行时会发生什么

我使用pyinstaller --log级DEBUG -F -d imports -w sample.py将.py转换为.exe

在更改为.exe之前，samply.py

#!/usr/bin/python
# -*- coding: utf-8 -*-
import os
import sys

from PySide.QtGui import QApplication, QMainWindow, QIcon, QMenu, QSystemTrayIcon

from test import Ui_MainWindow


class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self):

        super(MainWindow, self).__init__()
        self.setupUi(self)

        icon = QIcon("logo.png")
        menu = QMenu()
        menu = QMenu()
        hideAction = menu.addAction("Hide")
        hideAction.triggered.connect(self.hide)
        showAction = menu.addAction("Show")
        showAction.triggered.connect(self.show)
        self.setWindowIcon(QIcon("logo.png"))
        self.tray = QSystemTrayIcon()
        self.tray.setIcon(icon)
        self.tray.setContextMenu(menu)
        self.tray.setToolTip("Restart Scheduler!")
        self.show()


def main():

    app = QApplication(sys.argv)
    mainWin = MainWindow()
    ret = app.exec_()
    sys.exit(ret)


if __name__ == "__main__":
    main()

。ui文件转换为.py

        MainWindow.setWindowTitle(QtGui.QApplication.translate("MainWindow", "MainWindow", None, QtGui.QApplication.UnicodeUTF8))

Answer 1

资源的相对路径（例如徽标）是相对于sample.py的，但是当它们转换为.exe时，它们是相对于.exe的，因此有以下选项：

1. 将徽标复制到同一可执行文件夹中。

2. 使用--add-data命令设置为“数据”：pyinstaller --log-level DEBUG -F -d imports --add-data="logo.png;." -w sample.py并将sample.py修改为：

   # ...
   def resource_path(relative_path):
       """ Get absolute path to resource, works for dev and for PyInstaller """
       try:
           # PyInstaller creates a temp folder and stores path in _MEIPASS
           base_path = sys._MEIPASS
       except Exception:
           base_path = os.path.abspath(".")
   
       return os.path.join(base_path, relative_path)
   
   
   class MainWindow(QMainWindow, Ui_MainWindow):
       def __init__(self):    
           super(MainWindow, self).__init__()
           self.setupUi(self)    
           icon = QIcon(resource_path("logo.png"))
   
           menu = QMenu(self)
           hideAction = menu.addAction("Hide")
           hideAction.triggered.connect(self.hide)
           showAction = menu.addAction("Show")
           showAction.triggered.connect(self.show)
           self.setWindowIcon(QIcon(resource_path("logo.png")))
           self.tray = QSystemTrayIcon()
           self.tray.setIcon(icon)
           self.tray.setContextMenu(menu)
           self.tray.setToolTip("Restart Scheduler!")
           self.show()
   # ...
   

3. 创建一个.qrc，将其转换为.py并将其导入到sample.py：

   resource.qrc

   <RCC>
       <qresource prefix="/">
           <file>logo.png</file>
       </qresource>
   </RCC>
   

   pyside-rcc resource.qrc -o resource_rc.py
   

   sample.py

   # ...
   import resource_rc
   # ...
   class MainWindow(QMainWindow, Ui_MainWindow):
       def __init__(self):    
           super(MainWindow, self).__init__()
           self.setupUi(self)    
           icon = QIcon(":/logo.png")
   
           menu = QMenu(self)
           hideAction = menu.addAction("Hide")
           hideAction.triggered.connect(self.hide)
           showAction = menu.addAction("Show")
           showAction.triggered.connect(self.show)
           self.setWindowIcon(QIcon(":/logo.png"))
           self.tray = QSystemTrayIcon()
           self.tray.setIcon(icon)
           self.tray.setContextMenu(menu)
           self.tray.setToolTip("Restart Scheduler!")
           self.show()
   # ...
