wxStreamToTextRedirector newlines are lost

Question

I am getting result from wxStreamToTextRedirector as one line. The newlines are lost .... wxStreamToTextRedirector with just one parameter supposed to redirect output to cout, I have no clue why the newlines are not treated by cout, as such...

Update: a simplified example: produces the same result i.e newlines are lost.

    textctrl = new wxTextCtrl(this, -1, wxT(""), wxPoint(-1, -1),
     wxSize(250, 150));
{
    wxStreamToTextRedirector redirect(textctrl);
       string result = "line1\n Line2\n";
      cout << result;

}

Output ---> line1 Line2, as appears in the textctrl window. May it be that textctrl  
window does not interpret
\n correctly? I am using wxWidets on a Windows machine.

When creating a wxTextCtrl, by default it is created without support for multiple lines. You have to tell it that you intend to use multiple lines. If you are using Code::Blocks with wxSmith (which I recommend), you can specify that in the properties of the wxTextCtrl:

If you are creating it manually with code, you only need to specify wxTE_MULTILINE in the style parameter of the constructor, like this:

textctrl = new wxTextCtrl(this, -1, wxT(""), wxPoint(-1, -1), wxSize(250, 150),wxTE_MULTILINE);

For more information, you can check this page about the possible styles, and in particular, this section about the constructor.
