Making custom QProgressBar

Question

I'm getting the undefined reference to vtable for CustomProgressBar' error when trying to launch following code:
customprogressbar.h

#ifndef CUSTOMPROGRESSBAR_H
#define CUSTOMPROGRESSBAR_H
#include <QProgressBar>
#include "task.h"

class CustomProgressBar : public QProgressBar
{
Q_OBJECT
public:
    CustomProgressBar(DayTask, QWidget* parent = 0);
protected:
    void paintEvent(QPaintEvent *) Q_DECL_OVERRIDE;

private:
    DayTask task;
};

#endif // CUSTOMPROGRESSBAR_H

customprogressbar.cpp

#include "customprogressbar.h"
#include <QPainter>

CustomProgressBar::CustomProgressBar(DayTask task, QWidget* parent) :
    task{task},
    QProgressBar(parent)
{

}
//paintevent

What could cause the problem?

For further readers, this seems to be an issue becaus the `paintEvent` method is virtual and declared but not defined. — maxik, Jul 29 '16 at 20:12

Maybe moc (meta object compiler) is not being run for your header? Anyway, it's duplicate for this question

This should be a comment, not an answer. I realize you don't have the comment privilege yet, but it still stands. – jonspaceharper Jul 29 '16 at 11:24
