error: expected class-name before "{" token

[freekill]

So here's what I came up with my webcam.h:

#ifndef WEBCAM_H
#define WEBCAM_H
 
#include <QWaitCondition>
#include <QWidget>
#include "ui_webcam.h"
 
class CapturingThread;
class ImageBuffer;
class RenderingThread;
 
class WebcamWidget : public QWidget
{
    Q_OBJECT
 
    public:
       WebcamWidget(QWidget *parent=0);
       ~WebcamWidget();
 
    protected:
       void paintEvent(QPaintEvent* event);
 
    private slots:
       void startThreads();
       void haltThreads();
       void updatePixmap(QImage& image);
 
    private:
       Ui::webcam ui;
       CapturingThread* capturingThread;
       ImageBuffer* imageBuffer;
       RenderingThread* renderingThread;
       QPixmap pixmap;
       QWaitCondition waitCondition;
       QWaitCondition* pWaitCondition;
};
 
#endif

#ifndef WEBCAM_H
#define WEBCAM_H

#include <QWaitCondition>
#include <QWidget>
#include "ui_webcam.h"

class CapturingThread;
class ImageBuffer;
class RenderingThread;

class WebcamWidget : public QWidget
{
    Q_OBJECT

    public:
       WebcamWidget(QWidget *parent=0);
       ~WebcamWidget();

    protected:
       void paintEvent(QPaintEvent* event);

    private slots:
       void startThreads();
       void haltThreads();
       void updatePixmap(QImage& image);

    private:
       Ui::webcam ui;
       CapturingThread* capturingThread;
       ImageBuffer* imageBuffer;
       RenderingThread* renderingThread;
       QPixmap pixmap;
       QWaitCondition waitCondition;
       QWaitCondition* pWaitCondition;
};

#endif
