Ossi showed me what I missed.
We cannot just change stdout unconditionally.
So no reason to not do this, as long as the application call is prefixed
with "start /wait" to run it in the foreground.

#include <QApplication>
#include <qt_windows.h>
#include <cstdio>
#include <fcntl.h>
#include <io.h>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
HANDLE h = GetStdHandle(STD_OUTPUT_HANDLE);
if (h == INVALID_HANDLE_VALUE || h == NULL) {
if (!AttachConsole(ATTACH_PARENT_PROCESS))
return 1;
h = GetStdHandle(STD_OUTPUT_HANDLE);
int fd = _open_osfhandle((intptr_t)h, _O_TEXT);
if (fd <= 0)
return 2;
*stdout = *_fdopen(fd, "w");
setvbuf(stdout, NULL, _IONBF, 0 );
}
printf("Hello World from GUI app!\n");
QMetaObject::invokeMethod(&a, "quit", Qt::QueuedConnection);
return a.exec();
}
