Hello Everybody:

    I'm a wxWidget newbie, when I follow the tutorial in the wxwidget
website and i got a segment fault when i close the window, I'm using
Debian testing,  wxWidget ver is 2.6.3.2.1.5(Debian testing package),
the following is the code:

wxTestApp.h
==========================
#include "wx/wx.h"
#include "wxTestFrame.h"

#ifndef _WXTEST_APP_H
#define _WXTEST_APP_H

class wxTestApp : public wxApp
{
    virtual bool OnInit();
};

//IMPLEMENT_APP_NO_MAIN(wxTestApp)
IMPLEMENT_APP(wxTestApp)
#endif
==========================


wxTestApp.cpp
==========================
#include "wxTestApp.h"

bool wxTestApp::OnInit()
{
    wxTestFrame *frame = new wxTestFrame(_T("Hello World"),
wxPoint(50,50), wxSize(450,340) );
    frame->Show(TRUE);
    SetTopWindow(frame);
    return TRUE;
}
==========================

wxTestFrame.h
==========================
#include "wx/wx.h"

#ifndef _WXTEST_FRAME_H
#define _WXTEST_FRAME_H

class wxTestFrame: public wxFrame
{
public:
    wxTestFrame(const wxString& title, const wxPoint& pos, const wxSize& size);

    void OnQuit(wxCommandEvent& event);
    void OnAbout(wxCommandEvent& event);

    DECLARE_EVENT_TABLE()
};

#endif
==========================

wxTestFrame.cpp
==========================
#include "wxTestFrame.h"

typedef enum
{
    wxID_QUIT = 0,

};


BEGIN_EVENT_TABLE(wxTestFrame, wxFrame)
    EVT_MENU(wxID_QUIT, wxTestFrame::OnQuit)
END_EVENT_TABLE()

wxTestFrame::wxTestFrame(const wxString& title, const wxPoint& pos,
const wxSize& size)
: wxFrame((wxFrame *)NULL, -1, title, pos, size)
{
    wxMenu *menuFile = new wxMenu;

    menuFile->AppendSeparator();
    menuFile->Append( wxID_QUIT, _T("E&xit") );

    wxMenuBar *menuBar = new wxMenuBar;
    menuBar->Append( menuFile, _T("&File") );

    SetMenuBar( menuBar );

    CreateStatusBar();
    SetStatusText( _T("Welcome to wxWidgets!") );
}

void wxTestFrame::OnQuit(wxCommandEvent& WXUNUSED(event))
{
    Close(TRUE);
}
