VS QT - ui does not display newly added members (controls) || code is silent

Scenario 1: Create a new project, after editing in the ui, the newly added controls do not display code hints.

Scenario 2: Member ui reports an error Incomplete type is not allowed

Because I just started learning, it took two or three days to find a solution.

Online method: Recompile the ui file + rescan the solution (but I still can't solve it here)

Root cause: The header file of xxx.ui (ie ui_xxx.h) is missing. The header file is generated under debug/uic by default, so it is not added to the project by default, so it cannot be recognized.

There is no ui_xxx.h header file by default

Under the ui_xxx.h file, you can see that the members in the ui are included

Solution: Just add this header file.directory project\Debug\uic\ui_xxx.h

Solution:

Add to main.cpp

#if _MSC_VER >= 1600#pragma execution_character_set("utf-8")// This instruction only supports VS environment#endif
