Qt, no such slot error
- by Martin Beckett
I'm having a strange problem with slots in Qt4.6
I have a tree control that I am trying to fire an event back to the mainwindow to edit something.
I have boiled it down to this minimal example:
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
MainWindow(int argc, char **argv );
private Q_SLOTS:
void about() {QMessageBox::about(this, "about","about"); } // Just the defaul about box
void doEditFace() {QMessageBox::about(this, "test","doEditFace"); } // pretty identical
....
}
class TreeModel : public QAbstractItemModel
{
Q_OBJECT
Q_SIGNALS:
void editFace();
...
}
In my Mainwindow() I have
connect(treeModel, SIGNAL(editFace()), this, SLOT(about())); // returns true
connect(treeModel, SIGNAL(editFace()), this, SLOT(doEditFace())); // returns false
When I run it the second line gives a warning.
Object::connect: No such slot MainWindow::doEditFace() in \src\mainwindow.cpp:588
As far as I can see the doEditFace() is in the moc_ qmeta class perfectly correctly.
And the edit event fires and pops up the about box.
The order doesn't matterm if I connect the about box second it still works but my slot doesnt!
