[Qt-interest] Export Visual Studio 2008 projects to Qt

[Pedro Silva Vicente]

I initially created a .pro project from scratch and added each project file 
name on the .vcproj file  by hand  (vcproj  has an XML like syntax), but 
since the solution has thousands of files, I gave up quickly.

I ended up changing a Qt application that I am developing to just read the 
.vcproj  file  and export the file names to a text file that I used for the 
"SOURCES" and "HEADERS" part of the .pri Qt file.

The relevant code is here, feel free to use, with some tweaking this code 
can be changed to generate the .pro or .pri files directly.
The code reads the .vcproj  file and extracts each file name, located in the 
.vcproj file with the keyword "RelativePath" and saves each name to a new 
file "out.txt".

"file_name " in the parameter list is the name of the .vcproj file , 
obtained from

 fileName = QFileDialog::getOpenFileName(this,
        tr("Open File"), ".",
        tr("HDF5 files (*.h5);;All files (*.*)"));


void MainWindow::convert( const char* file_name )
{

    FILE       *fr;
    FILE       *fw;
    char       s[512];
    int        c;
    int        index;
    int        len;
    QString    name;
    QByteArray ba;


    fr = fopen(file_name, "r");
    fw = fopen("out.txt", "w");
    if ( fr == NULL )
    {
        return;
    }


    c = getc(fr);
    while (c != EOF)
    {

        fscanf( fr, "%s", s );

        QString str( s );
        QString path ( "./src/" );

        if ( str.contains( "RelativePath" ) )
        {

            index = str.lastIndexOf ( QChar('\\' ) );
            len   = str.length();
            name  = str.right( len - index - 1 );
            name.chop( 1 );
            path.append( name );
            path.append( " \\" );

            ba = path.toLatin1();
            fwrite( ba.data(), sizeof( char ), path.length(), fw );
            fwrite( "\n", sizeof( char ), 1, fw );
        }


        c = getc(fr);
    }
    fclose(fr);
    fclose(fw);

    return;



}
