qt ui 转python

news 来源：原创 2025/6/6 7:45:34

系统没有 pyside6-uic，只能自己搞一个；同时将 pyside 和 pyqt 合并到代码\bin\pyside-uic.py里；

用法: python pyside-uic.py [PyQt6/PyQt5/PySide6/PySide2] <输入路径> [-o <输出路径>] [--skip/--force]

可以根据自己的要求选择转为PyQt6 、PyQt5、PySide6、PySide2的python代码；

--skip：检测文件对应输出的python代码是否已生成，每个生成输出的py文件都包含ui文件的MD5，MD5用于判断ui文件是否有修改，如果没有修改就跳过；

--force：不检查ui文件是否有修改，强制将ui文件转换生成对应的py文件；

\bin\pyside6-uic

#!/bin/bash
#pyside-uic "PySide6" "$@"
exec /ucrt64/bin/python.exe /ucrt64/bin/pyside-uic.py "PySide6" "$@"

\bin\pyside2-uic

#!/bin/bash
# uic.exe -g python
#pyside-uic "PySide2" "$@"
exec /ucrt64/bin/python.exe /ucrt64/bin/pyside-uic.py "PySide2" "$@"

\bin\pyuic6

#!/bin/sh
#exec /ucrt64/bin/python.exe -m PyQt6.uic.pyuic ${1+"$@"}
#pyuic PyQt6 ${1+"$@"}
exec /ucrt64/bin/python.exe /ucrt64/bin/pyside-uic.py "PyQt6" "$@"

\bin\pyuic5

#!/bin/sh
#exec /ucrt64/bin/python.exe -m PyQt5.uic.pyuic ${1+"$@"}
#pyuic PyQt5 ${1+"$@"}
