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

My current .pro file looks as:

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


./release\editorwidget.o:editorwidget.cpp:(.text+0x3 13): undefined reference to `_imp___ZN6EditorC1EP7QWidget'

./release\moc_editor.o:moc_editor.cpp:(.text+0x26): undefined reference to `_imp___ZN6Editor16staticMetaObjectE'

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.
