Pyuic4-o file name. py Project name. UI

The-X option indicates whether additional test code is generated to display the window, and it is recommended that this parameter be added so that it is easy to debug and run directly.

– The generated PY file

Contains the Ui_dialog class as the interface description code

– can be edited directly as the project master file

Run if you add the following code

If__name__ == "__main__":  ImportSys App= Qtgui.Qapplication(Sys.Argv)  Dialog = Qtgui.Qdialog()  ui = ui_dialog ()   ui. (dialog)  < Span class= "PLN" > dialog. ()   sysexit (app.exec_ ())

– Dependent

MSVCP90.dll (I don't know why I just want this file, the other MSVCPxxx.dll doesn't seem to work)

Placed under the C:\Windows\System32

– Using the project directory where you want to package the file, double-click Execute when you want to package, generate the executable file under dist/(the name specified in the file setup.windows)
