error: expected class-name before "{" token

I'm getting this compile-time error pointing to the widget class that I inherited from QWidget. I only recycled the previous code I was using I don't know why I'm getting this error.

In the file included from main.cpp:2:
webcam.h:13: error: expected class-name before "{" token

Attached are the files main.cpp and webcam.h

Both QWidget and Ui::webcam are QObject children while you can inherit from 1 QObject only (inheritance from multiple QObject's will not work ). You can try to encapsulate Ui::webcam as member.

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

Code:

---

#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

This time, flagged me 2 errors.
error: using-declaration for non-member at class scope
error: expected ";" before "ui"

Explore/show ui_webcam.h file. Imho there is no Ui::webcam class.

Or it should be something like:

Code:

---

webcam ui;

So I see. I didn't name the Ui webcam it was Ui::camWidget. This is what flagged me the error. Thanks.
