QDebug output in qtcreator after setting custom QtMessageHandler

I want to save the QDebug message to a log file, so I set QtMessageHandler.

And I still want the message display in qtcreator's view Application Output,

so I use std::cout/std::cerr to print the message in my custom QtMessageHandler.

When I run app, msg can display both in mingw and msvc build kit, but things differs when I debug app :

The msg can display in mingw/gdb, but can't in msvc/cdb.

Is it an issue of qtc?
