QTextBrowser for Helper

I am trying to make a helper with QTextBrowser. As I understood, home(), backward() and forward() are already implemented in QTextBrowser and required only connections to the buttons. Below there is .h and .cpp files

#ifndef HELPWINDOW_H
#define HELPWINDOW_H

#include <QDialog>

namespace Ui {
class HelpWindow;
}

class HelpWindow : public QDialog
{
    Q_OBJECT

public:
    explicit HelpWindow(QWidget *parent = 0);
    ~HelpWindow();

private slots:

private:
    Ui::HelpWindow *ui;
};


#endif // HELPWINDOW_H

and

#include "helpwindow.h"
#include "ui_helpwindow.h"

HelpWindow::HelpWindow(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::HelpWindow)
{
    ui->setupUi(this);

// connection
    connect(ui->pushButton_home,SIGNAL(clicked()),ui->textBrowser,SLOT(home()));
    connect(ui->pushButton_forward,SIGNAL(clicked()),ui->textBrowser,SLOT(forward()));
    connect(ui->pushButton_backward,SIGNAL(clicked()),ui->textBrowser,SLOT(backward()));
}

HelpWindow::~HelpWindow()
{
    delete ui;
}

enter image description here

There is no any error message. It is possible to read and click the links inside QTextBrowser. Only there are no any actions with buttons. What do I miss here?

Solution

  • I found why it did not work. The initial source should be specify:

    ui->textBrowser->setSource(QUrl::fromLocalFile("help/index.html"));

    Thank you, Jens for spending time.
