[SOLVED]QObject subclass compile error

fluca1978

Hi all,
I cannot see the problem within this class:

@

class TableViewHandler : public QObject
{
Q_OBJECT
public:
TableViewHandler( QObject* parent = 0 );
...
}

// implementation
TableViewHandler::TableViewHandler( QObject* parent) : QObject(parent) {
// do stuff
}
@

which I cannot compile getting the error:

@tableviewhandler.o: In function TableViewHandler': /sviluppo/c/WHR-build-desktop/../WHR/tableviewhandler.cpp:5: undefined reference to vtable for TableViewHandler'
/sviluppo/c/WHR-build-desktop/../WHR/tableviewhandler.cpp:5: undefined reference to vtable for TableViewHandler' tableviewhandler.o: In function ~TableViewHandler':

make: *** [WHR] Error 1
The process "/usr/bin/make" exited with code 2.
Error while building project WHR (target: Desktop)
When executing build step 'Make'@

no matter what my constructor does. Any suggestion?

Clean the project and re-run qmake.

That should do the trick.

I did a clean all and build again, but it did not solved the problem.

...and ran qmake? I usually get those errors when the generated moc files no longer matches the class as it is now. I would also recommend manually deleting all generated files.

A clean alone does not remove the generated files, nor does it cause qmake to run.

Correct, the right sequence is clean all, run qmake, build all.
