ISO C++ forbids declaration of 'QPushButton' with no type in QT Creator
- by Mohit Deshpande
I am running QT Creator on a Linux Ubuntu 9.10 machine. I just got started with QT Creator, and I was going through the tutorials when this error popped up while I was trying to build my project: "ISO C++ forbids declaration of 'QPushButton' with no type". This problem appears in my header file:
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QtGui/QWidget>
namespace Ui
{
class MainWindow;
}
class MainWindow : public QWidget
{
Q_OBJECT
public:
MainWindow(QWidget *parent = 0);
~MainWindow();
public slots:
void addContact();
void submitContact();
void cancel();
private:
Ui::MainWindow *ui;
QPushButton *addButton;
QPushButton *submitButton;
QPushButton *cancelButton;
QLineEdit *nameLine;
QTextEdit *addressText;
QMap<QString, QString> contacts;
QString oldName;
QString oldAddress;
};
#endif // MAINWINDOW_H
