extend QScintilla class

[creatio.x]

I've been trying to extend the QScintilla class to add some functionality that I'm missing, but I keep running into some errors. My header file looks like the following:

#ifndef EDITOR_H
#define EDITOR_H
 
#include <QKeyEvent>
#include <Qsci/qsciglobal.h>
#include <Qsci/qsciscintilla.h>
 
class QSCINTILLA_EXPORT Editor : public QsciScintilla
{
    Q_OBJECT
 
    public:
        Editor(QWidget* parent = 0);
        virtual ~Editor();
 
    signals:
 
    public slots:
        void keyPressEvent(QKeyEvent* e);
 
    private:
 
};
 
#endif // EDITOR_H

#ifndef EDITOR_H
#define EDITOR_H

#include <QKeyEvent>
#include <Qsci/qsciglobal.h>
#include <Qsci/qsciscintilla.h>

class QSCINTILLA_EXPORT Editor : public QsciScintilla
{
    Q_OBJECT

    public:
        Editor(QWidget* parent = 0);
        virtual ~Editor();

    signals:

    public slots:
        void keyPressEvent(QKeyEvent* e);

    private:

};

#endif // EDITOR_H

When I compile this though, I keep getting the following errors:

I have no clue what is going on here. My guess would be that I would have to define Editor in a separate project and export it's own .dll file and use that inside my project.

I think you should remove the QSCINTILLA_EXPORT from the class definition.
