Я использую Code::Blocks 8.02 и компилятор mingw 5.1.6. Я получаю эту ошибку, когда компилирую свой проект Qt:
C:\Documents and Settings \ Fuzz\Desktop\GUI\App_interface.cpp | 33 | undefinedссылка на `vtable для AddressBook '
Файл AddressBook.h:
#ifndef ADDRESSBOOK_H
#define ADDRESSBOOK_H
#include <QWidget>
class QLabel;
class QLineEdit;
class QTextEdit;
class AddressBook : public QWidget
{
Q_OBJECT
public:
AddressBook(QWidget *parent = 0);
private:
QLineEdit *nameLine;
QTextEdit *addressText;
};
#endif
Файл AddressBook.cpp:
#include <QtGui>
#include "addressbook.h"
AddressBook::AddressBook(QWidget *parent)

{
QLabel *nameLabel = new QLabel(tr("Name:"));
nameLine = new QLineEdit;
QLabel *addressLabel = new QLabel(tr("Address:"));
addressText = new QTextEdit;
QGridLayout *mainLayout = new QGridLayout;
mainLayout->addWidget(nameLabel, 0, 0);
mainLayout->addWidget(nameLine, 0, 1);
mainLayout->addWidget(addressLabel, 1, 0, Qt::AlignTop);
mainLayout->addWidget(addressText, 1, 1);
setLayout(mainLayout);
setWindowTitle(tr("Simple Address Book"));
}
