Error when playing exercises

[lima_will]

Guys,
I'm trying to reproduce this example:

http://www.codeprogress.com/cpp/libr...ectHeaderClick

I'm using QT5, only returns me the error:

/home/will/Qt - Projetos/Telas/Variaveis.h:15: error: 'setClickable' was not declared in this scope

My current class is as follows:

#include <QMessageBox>
#include <QHeaderView>
#include <iostream>
#include <QtGui>
 
class myHeaderView : public QHeaderView
{
Q_OBJECT
public:
      myHeaderView():QHeaderView(Qt::Horizontal)
      {
        he
          setClickable(true);
        connect(this,SIGNAL(sectionClicked(int)),this,SLOT(sectionClicked(int)));
      }
      ~myHeaderView(){}
 
public slots:
      void sectionClicked(int index)
      {
        QMessageBox::about(this,"Hi! Header Click Detected!","Index:"+QString::number(index));
      }
 
};

#include <QMessageBox>
#include <QHeaderView>
#include <iostream>
#include <QtGui>

class myHeaderView : public QHeaderView
{
Q_OBJECT
public:
      myHeaderView():QHeaderView(Qt::Horizontal)
      {
        he
          setClickable(true);
        connect(this,SIGNAL(sectionClicked(int)),this,SLOT(sectionClicked(int)));
      }
      ~myHeaderView(){}

public slots:
      void sectionClicked(int index)
      {
        QMessageBox::about(this,"Hi! Header Click Detected!","Index:"+QString::number(index));
      }

};

Hello,
just look at the link you sent its not the same code... Syntax Errors.
you missed a couple of ; and you added he by mistake etc... fix the errors.
is it your first day of programming ?
good luck.
