connection error in QObject::connect()

[Pogi]

how do i make syntax highlighting for c++ when creating thread in this forum?

no matching function for call to 'MainWindow::connect(ServerManager*, const char*, MainWindow*, const char*)'
QObject::connect(&server,SIGNAL(display()),this,SLOT(display()));

why i keep getting this error.

class MainWindow
{
ServerManager server;
MainWindow()
{
QObject::connect(&server,SIGNAL(display()),this,SLOT(display()));
}
private slots:
void display();
};

void MainWindow::display()
{
std::string m;
sf::Int32 i;
server.getPacket() >> m >> i;
if ( i == 0 )
{
ui->clientList->addItem(QString::fromStdString("m"));
}
}

class ServerManager
{
public:
void test();
signals:
void display();
}

void ServerManager::test()
{
emit display();
}

Both your classes need to inherit from QObject for the signal/slot mechanism to work.

Code blocks are either preceded by 4 spaces (good for one liners):

int variable;

or they can be enclosed by `` ` (triple back ticks, good for inline elements and longer blocks):

#include <iostream>

int main (int argc, char * argv[]) {
   std::cout << "Hello, World!\n";
}
