PySide6直接载入UI文件实现界面和代码分离

2024-01-15 19:48:16

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
