Ouch! Yes of course, and by adding / changing SigTest :

private slots:
     void setLegend(const QString &) ;

if (connect(pTest, SIGNAL(Boo(const QString &)), this, 
SLOT(setLegend(const QString &)), Qt::QueuedConnection))

void SigTest::setLegend(const QString & msg)
{
     ui.pushButton->setText(msg) ;
}

Success.

But with that said my original submission still stands, it still doesn't 
work even though the slots have been defined in the main UI header and 
implemented in source.

I can see why the original test doesn't work, after all it is a bit of a 
screamer, but why my original doesn't is beyond me.

I have since included the SignalTest class and the slot definition and 
implementation from SigTest in to my original application and it still 
doesn't work.

private slots:
	void setLegend(const QString &) ;

void MyApp::setLegend(const QString & msg)
{
	ui->statusBar->showMessage(msg, 0) ;
}

pTest = new SignalTest() ;
if (connect(pTest, SIGNAL(Boo(const QString &)), this, 
SLOT(setLegend(const QString &)), Qt::QueuedConnection))
{
	pTest->Start() ;
}

Object::connect: No such slot MyApp::setLegend(const QString &) in 
MyApp.cpp:268
Object::connect:  (receiver name: 'MyApp')

Anyone?
