cout redirection problem: wxWidgets 2.8.7, MinGW, Windows XP

[MattPhillips]

Hello,

I am posting this to both C::B and wxWidgets boards, since I don't know where the problem it is.  Here it is, step by step:

1) I download CB 8.02 with the MinGW compiler and install in C:\CodeBlocks.  (OS: Windows XP)

2) I download wxWidgets (not wxPack) and install it in C:\SourceCode\Libraries\wxWidgets-2.8.7 (default).

3) I go into ...\include\wx\msw\setup.h and set wxUSE_STD_IOSTREAM to 1.  Just for good measure I do the same in setup0.h and setup_microwin.h

4) I create the following .bat file as per the instructions at http://wiki.wxwidgets.org/Compiling_WxWidgets_With_MSYS-MinGW, under "Setting up MinGW"

@echo off
set path=C:\CodeBlocks\MinGW\bin;%PATH%
set LIBRARY_PATH=C:\CodeBlocks\MinGW\lib
set C_INCLUDE_PATH=C:\CodeBlocks\MinGW\include
set CPLUS_INCLUDE_PATH=C:\CodeBlocks\MinGW\include\c++\3.4.5;C:\CodeBlocks\MinGW\include\c++\3.4.5\backward;C:\CodeBlocks\MinGW\include\c++\mingw32;C:\CodeBlocks\MinGW\include

5) I name this 'ConfigWX.bat' and put it in C:\SourceCode\Libraries\wxWidgets-2.8.7.

6) I open up the command line and cd C:\SourceCode\Libraries\wxWidgets-2.8.7, and then run ConfigWX.bat.

7) I enter gcc -v to make sure MinGW sees the directory; it does.

8 ) I cd build\msw and first run MinGW with the 'clean' option, since by now I have compiled and re-compiled several times:

mingw32-make -f makefile.gcc SHARED=1 MONOLITHIC=1 BUILD=debug UNICODE=0 USE_OPENGL=1 clean

Running this takes about a minute.

9) Now I compile:

mingw32-make -f makefile.gcc SHARED=1 MONOLITHIC=1 BUILD=debug UNICODE=0 USE_OPENGL=1

This takes about a half-hour.

10) Open C::B, using the wxWidgets default template, and modify the App.cpp file so that it cout is redirected to a wxTextCtrl I create, using wxTextCtrl:

#ifdef WX_PRECOMP
#include "wx_pch.h"
#endif

#ifdef __BORLANDC__
#pragma hdrstop
#endif //__BORLANDC__

#include "testTextApp.h"
#include "testTextMain.h"#include <wx/textctrl.h>
#include <iostream>
using namespace std;

IMPLEMENT_APP(testTextApp);

bool testTextApp::OnInit()
{
    testTextFrame* frame = new testTextFrame(0L);
    frame->SetIcon(wxICON(aaaa)); // To Set App Icon
    frame->Show();

    wxTextCtrl* textctl = new wxTextCtrl(frame, wxID_ANY);
    wxStreamToTextRedirector redirect(textctl);

    cout << "Please work...\n";

    textctl->Show();
    return true;
}

When I do this I get "error: 'wxStreamToTextRedirector' was not declared in this scope".  Note that I have included <wx/textctrl.h>, which is the only #includelisted in the wxStreamToTextRedirector doc page.

11) Trying to redirect using rdbuf() also doesn't work; the following includes test cut and pasted from the wxTextCtrl doc page:

#ifdef WX_PRECOMP
#include "wx_pch.h"
#endif

#ifdef __BORLANDC__
#pragma hdrstop
#endif //__BORLANDC__

#include "testTextApp.h"
#include "testTextMain.h"
#include <wx/textctrl.h>
#include <iostream>
using namespace std;

IMPLEMENT_APP(testTextApp);

bool testTextApp::OnInit()
{
    testTextFrame* frame = new testTextFrame(0L);
    frame->SetIcon(wxICON(aaaa)); // To Set App Icon
    frame->Show();

    wxTextCtrl* textctl = new wxTextCtrl(frame, wxID_ANY);
    textctl->Show();

    streambuf *sbOld = cout.rdbuf();
    cout.rdbuf(*textctl);

    cout << "To TextCtrl\n" << endl;

    cout.rdbuf(sbOld);

    cout << "To console\n";

    return true;
}

Now the error, at 'cout.rdbuf(*textctl);' is:

error: no matching function for call to `std::basic_ostream<char, std::char_traits<char> >::rdbuf(wxTextCtrl&)'|

This happens even when I include

#define NO_TEXT_WINDOW_STREAM

in the textctrl.h file.

So, what is going on?! Apparently nobody else is having this problem, but I can't figure out what's going on.  It seems particularly strange that wxStreamToTextRedirector isn't even defined in textctrl.h.

Definitely this problem is with wx; not with C::B.

BTW why have you added the poll?? :?:

Hi,

It's my first time on this board and it wouldn't let me post unless I selected two 'options'.  I really had no idea what it meant so I just put in keywords.

I see. Aparently most newbies are posting a poll. May be it's the reason behind. Thanks for posting it.

@Yiannis, Thomas: Can we fix this?

[MattPhillips]

Just to be clear--I had no intention of posting a poll, I just followed the defaults.

To clear my previous message, I was glad to know the problem other users faces.

Nothing to fix here, really.

If guys click on "Create new poll" instead of "Create new topic" we cannot do anything about that. Creating a new topic as newbie (first topic posted ever) just works fine.

Edit:
Thomas: As a newbie I was in fact still able to create a poll. So this "feature" of yours to avoid this does not work. ;-)

Okay, I get it... Oops... 8 pt. text isn't easy to read on my laptop, what can I say...

Best,
