Expected class-name before '{' token error

[tomy]

Hi guys,

I'm working on an example program. The program is finished but I get this error when running:

error: expected class-name before '{' token
{
^

This is sortdialog.h which the error belongs to:

#ifndef SORTDIALOG_H
#define SORTDIALOG_H

#include <QDialog>
#include "ui_sortdialog.h"

class SortDialog : public QDialog, public Ui::SortDialog
{                                 // The error points to this line
    Q_OBJECT

public:
    SortDialog(QWidget* parent = 0);
    void setColumnRange(QChar first, QChar last);
};

#endif // SORTDIALOG_H

This in the main.cpp file too:

#include <QApplication>
#include "sortdialog.h"

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    SortDialog* dialog = new SortDialog;
    dialog -> setColumnRange('C', 'F');
    dialog -> show();
    return app.exec();
}

What is this error for please?

i think you need a namespace when you want to take this classname. i could be wrong. try to change the classname or namespace it.

Hi, did you check if uic (User Interface Compiler) ran without error? It seems that the compiler does not recognize Ui::SortDialog as a proper class name. Double check the contents of ui_sortdialog.h, you should see something like

namespace Ui {
    class SortDialog: public Ui_SortDialog {};
} // namespace Ui

in the end.

Thank you. The problem belonged to the .pro file.
It's solved now.
