No Matching function to call...

Hy,

I'm a bit new to Qt and C++ (even if I have program in different languages).

I've got a search box with this in (searchFiled is a QLineEdit):

connect(this->m_ui->searchField, SIGNAL(textEdited(const QString &)),
            this, SIGNAL(searchStringChanged(const QString &)));

connect(this->m_ui->searchField, SIGNAL(textEdited(const QString &)),
            this, SIGNAL(searchStringChanged(const QString &)));

To copy to clipboard, switch view to plain text mode 

In my main window constructor I dot that:

m_searchdialog = new searchDialog();
m_searcher = new searcher();
 
connect(m_searchdialog, SIGNAL(searchStringChanged(const QString &)),
        m_searcher, SLOT(newResearch(const QString &)));

m_searchdialog = new searchDialog();
m_searcher = new searcher();

connect(m_searchdialog, SIGNAL(searchStringChanged(const QString &)),
        m_searcher, SLOT(newResearch(const QString &)));

To copy to clipboard, switch view to plain text mode 

And when I compile I've got this error:

mainwindow.cpp:19: error: no matching function for call to ‘mainWindow::connect(searchDialog*&, const char [38], searcher*&, const char [30])’

Any idea ?
Because I'm stuck for 2 hours... I'm a little bit bored now :P

3 possibilites:

1) the place you call connect in is not a subclass of QObject
2) m_searcher is not a subclass of QObject
3) m_searchdialog is not a subclass of QObject

usually it's 1)

HTH

PS: if it is 1), you may fix it with

receiver->connect(sender, SIGNAL(...), SLOT(...));

receiver->connect(sender, SIGNAL(...), SLOT(...));

Actually it was 2).

May I worship you ? :P
