Problem with connect

Hey all,

I have a problem using connect. Currently i am using the QXmpp library to make chat a program that can be used over the google network.

Now i am following there examples to create a basic application, specifically this example http://qxmpp.googlecode.com/svn/trun...les/GuiClient/ .

In there constructor they have this line of code:

Code:

---

check = connect(&m_xmppClient.rosterManager(),
                         SIGNAL(rosterChanged(const QString&)),
                         this, SLOT(rosterChanged(const QString&)));

---

Where m_xmppClient is:

Code:

---

QXmppClient m_xmppClient;

---

That should return this.

But when i do this in my application:

Code:

---

connect(&chatClient.rosterManager(), SIGNAL(rosterReceived()), this, SLOT(rosterReceived()));

---

With chatClient being:

Code:

---

QXmppClient chatClient;

---

I get the following error:

Code:

---

../ChatApp/maindialog.cpp: In member function 'void mainDialog::createActions()':
../ChatApp/maindialog.cpp:56: error: no matching function for call to 'mainDialog::connect(QXmppRosterManager*, const char*, mainDialog* const, const char*)'

---

But i don't get this error on there example

looks like Qt::ConnectionType missing where you call function mainDialog::connect(QXmppRosterManager*, const char*, mainDialog* const, const char*, right_here)

It has nothing to do with the 5th parameter. You are missing a header file which tells the compiler that QXmppRosterManager is a QObject. So try

Code:

---

#include "QXmppRosterManager.h"

---

Thanks that worked
