Overview

This code snippet demonstrates how to use QTextBrowser. The QTextBrowser class extends QTextEdit and provides a rich text browser with hypertext navigation.

Note: In order to use this code, you need to have Qt installed on your platform.

Header

#include <QWidget>
#include <QTextBrowser>
#include <QVBoxLayout>
 
class MyWidget : public QWidget
    {
    Q_OBJECT
 
    public:
        MyWidget(QWidget *parent = 0);
        ~MyWidget();
        void setText(QString);
 
    private:
        QTextBrowser*   textBrowser;
    };

Source

MyWidget::MyWidget(QWidget *parent)
    : QWidget(parent)
    {
    // Create text browser
    textBrowser = new QTextBrowser(this);
 
    // Set it read only
    textBrowser->setReadOnly(true);
 
    // Do not show frames    
    textBrowser->setFrameStyle(true);
    textBrowser->setFrameStyle(QFrame::Plain);
 
    // NOTE: That allows to open links from the html code
    textBrowser->setOpenExternalLinks(true);
 
    // Use layout
    QVBoxLayout* layout = new QVBoxLayout;
    layout->addWidget(textBrowser);
    setLayout(layout);
    }
 
void MyWidget::setText(QString data)
    {
    // Set some html data into QTextBrowser
    textBrowser->setHtml(data);
    }
 
MyWidget::~MyWidget()
    {
    }

Postconditions

QTextBrowser shows HTML and the device's web browser follows the link when the user selects it.
