Python 使用 PyQt5 设计一个查询IP对话框程序

当前环境：Win10 x64 + Python 3.8.10 + PyQt==5.15.2 + PyQt-tools==5.15.9.33

1 打开 designer.exe ,新建一个 Dialog without Buttons , 设计窗体。
C:\Python\Python38-32\Lib\site-packages\qt5_applications\Qt\bin\designer.exe

2 使用命令转换为 py
C:\Python\Python38-32\Scripts\pyuic5.exe -x dialog.ui -o dialog.py

说明: -x 会产生 __main__ 函数。

3 实现查询和调用。

dialog.py

4 运行 mydialog.py
