[QScintilla] No syntax highlighting with provided example

[DYNAWORKS, Tools]

Hello,
I have just compiled source code of QScintilla to use it in an editor. All seems good, but I have no syntax highlighting whereas I have created a QsciLexerCPP and set it to the QsciScintilla object. Here is the code I use to test some functionalities :

#include <QApplication>
#include <QScintilla/Qsci/qsciscintilla.h>
#include <QScintilla/Qsci/qscilexercpp.h>

int main(int argc, char* argv[])
{
     QApplication app(argc, argv);

     QsciLexerCPP *lexerCPP = new QsciLexerCPP;
     lexerCPP->setColor(Qt::magenta, QsciLexerCPP::Comment);

     QsciScintilla *scintilla = new QsciScintilla;
     scintilla->setLexer(lexerCPP);
     scintilla->SendScintilla(QsciScintilla::SCI_SETHSCROLLBAR, 0);
     scintilla->setMinimumSize(600, 450);
     scintilla->setText("#include <toto.hg>\n#define titi 12\n\n\n\n");

     scintilla->show();

     return app.exec();
}

Here is what I get at program execution, there is no color for specific syntax elements, someone might have an idea of my problem ?
Thanks, regards
Julien
