How to redirect qml's console.log() to cpp stdout

[singingsingh]

I am using qml( qtCreator ) and cpp (visual studio).

Usually the error messages are shown to the console, both from cpp and qml.

My requirement is that I should not have a console.

So I wrote a window application.

But when a flag has been set, I should launch a console. And show the corresponding error messages there.

I have used the following code in a function to set up this.

@HANDLE handle_out = GetStdHandle(STD_OUTPUT_HANDLE);
int hCrt = _open_osfhandle((long) handle_out, _O_TEXT);
FILE* hf_out = _fdopen(hCrt, "w");
setvbuf(hf_out, NULL, _IONBF, 128);

// redirecting the buffers to the file handle
*stdout = *hf_out;
*stderr = *hf_out;

//attach std input to console
HANDLE handle_in = GetStdHandle(STD_INPUT_HANDLE);
hCrt = _open_osfhandle((long) handle_in, _O_TEXT);
FILE* hf_in = _fdopen(hCrt, "r");
setvbuf(hf_in, NULL, _IONBF, 128);
*stdin = *hf_in;@

This will print the error log from stdout and stderr to a console.

To redirect qt error logs we can use.

How to redirect qDebug, qWarning, qCritical etc output?

But how do we redirect the output from console.log() of qml to the console.

Thanks in advance.
