[Qt-interest] Slots in threads ?

[Patric]

Hi John,
actually my connection is:

 connect(ui->gameBoard_Widget, SIGNAL(continueAuto()),
ui->gameWorld_Widget->getSimulationEngine(), SLOT(continueAuto()));


and the error is :

mainwindow.cpp: In constructor `MainWindow::MainWindow(QWidget*)':
mainwindow.cpp:35: error: no matching function for call to 
`MainWindow::connect(GameBoard*&, const char*, SimulationEngine*, const 
char*)'

c:/Qt/2009.03/qt/include/QtCore/../../src/corelib/kernel/qobject.h:202: 
note: candidates are: static bool QObject::connect(const QObject*, const 
char*, const QObject*, const char*, Qt::ConnectionType)

c:/Qt/2009.03/qt/include/QtCore/../../src/corelib/kernel/qobject.h:308: 
note: bool QObject::connect(const QObject*, const char*, const char*, 
Qt::ConnectionType) const



where the getSimulationEngine() returns a pointer, gameBoard_Widget is 
actually promoted widget and continueAuto() is slot in the thread. 
SimulationEngine is a thread.

Regards
