[solved] unable to accessing signal 'textChanged' from base 'QLineEdit' class

[hans977]

I have a class like this:

@class MathEditPoint : public QLineEdit {
Q_OBJECT

public:
MathEditPoint(QWidget * parent);

 . . . . .

public slots:
void upDateSize( const QString & text );

 . . . . .  

};

MathEditPoint::MathEditPoint(QWidget * parent)
: QLineEdit(parent) {
connect(this, SIGNAL( textChanged( const QString & text ) ),
this, SLOT( upDateSize( const QString & text ) ));

. . . . .

}@

I get the following error when running:
Object::connect: No such signal MathEditPoint::textChanged( const QString & text ) in MathEditPoint.cpp

According the the documentation the base class QlineEdit has a single “void QLineEdit::textChanged ( const QString & text ) [signal]”. Why can I not access it?

Thanks

You should write:

@
connect(this, SIGNAL(textChanged(QString)), this, SLOT(upDateSize(QString)));

[utcenter]

you don't need identifiers in the signals, just the type

Thanks for the fast reply. The example I was looking at did not have parameters so I missed that.
