PySide6直接载入UI文件实现界面和代码分离
作者：互联网
直接载入，无需再生成相应的py文件。
参考：Using .ui files from Designer or QtCreator with QUiLoader and pyside6-uic — Qt for Python
入口文件 simpleApp.py
from mainWindow import Window
from qt import QApplication, QIcon, _exec
if __name__ == '__main__':
app = QApplication([])
app.setWindowIcon(QIcon("logo.png")) # 添加图标
w = Window()
w.ui.show()
#w.win.show()
_exec(app)
simpleApp.py
界面控件属性设置文件 mainWindow.py

mainPage.ui
以下文件用于扩展相关功能，但是入口文件中会用到，需要import：
PyQt6和PySide6兼容设置 qt.py：
import sys
if 'PyQt6' in sys.modules:
# PyQt6
from PyQt6 import QtGui, QtWidgets, QtCore
from PyQt6.QtCore import pyqtSignal as Signal, pyqtSlot as Slot
else:
# PySide6
from PySide6 import QtGui, QtWidgets, QtCore
from PySide6.QtCore import Signal, Slot
from PySide6.QtWidgets import QApplication
from PySide6.QtGui import QIcon
def _enum(obj, name):
parent, child = name.split('.')
result = getattr(obj, child, False)
if result: # Found using short name only.
return result
obj = getattr(obj, parent) # Get parent, then child.
return getattr(obj, child)
def _exec(obj):
if hasattr(obj, 'exec'):
return obj.exec()
else:
return obj.exec_()
qt.py
打包部署需要用到的，实现dll文件整理到dist\lib文件夹下（试了一下功能未实现，仅做记录，寻找解决方案，如有解决方案的朋友请不吝赐教）
import sys
import os
currentdir = os.path.dirname(sys.argv[0]).replace("/","\\")
libdir = os.path.join(currentdir, "lib")
sys.path.append(libdir)
os.environ['path'] += './lib'
print(sys.path)
print(f"\n{os.environ['path']}")
runtimehook.py
调用命令，结束后需要拷贝相应的UI文件到生成的目录：
pyinstaller simpleapp.py --noconsole --hidden-import PySide6.QtXml --workpath D:\Projects\PythonAPP\SimpleAPP\build --distpath D:\Projects\PythonAPP\SimpleAPP\build\dist --runtime-hook="runtimehook.py"Command line
