Название: Не могу создать производный класс от QComboBox
Отправлено: xintrea от Январь 13, 2014, 00:00
Делаю следующий примитивный класс: Заголовок: C++ (Qt) #ifndef __MTCOMBOBOX_H__
#define __MTCOMBOBOX_H__
#include <QObject>
#include <QWidget>
#include <QComboBox>
#include <QStyledItemDelegate>
class MtComboBox : public QComboBox
{
Q_OBJECT
public:
MtComboBox(QWidget *parent=0);
virtual ~MtComboBox();
private:
QStyledItemDelegate* itemDelegate;
};
#endif /* __MTCOMBOBOX_H__ */
Реализация: C++ (Qt) #include "main.h"
#include "MtComboBox.h"
MtComboBox::MtComboBox(QWidget *parent) : QComboBox(parent)
{
Q_UNUSED(parent);
itemDelegate = new QStyledItemDelegate();
this->setItemDelegate(itemDelegate);
}
MtComboBox::~MtComboBox()
{
if(itemDelegate!=NULL)
delete itemDelegate;
}
Использование: C++ (Qt) #include "libraries/MtComboBox.h"
...
MtComboBox *language;
...
language=new MtComboBox(this);

Не пойму, что сделал не так? Недавно вернулся к C++, многое подзабыл, посему ошибок у себя не вижу. Если кого интересует для чего такой класс нужен, то вот: http://stackoverflow.com/questions/13308341/qcombobox-abstractitemviewitem

Ты его не сишным ли компилятором пытаешься собирать? :)

Нет, это часть Qt-шного проекта, собирается через qmake. В *.pro файле в секциях сырцов и хидеров оба файла прописаны. Что еще нужно не пойму.

в чистом проекте тоже такие ошибки?
