You could start a web browser in QProcess. If you like to have an external browser.

Within Qt how about "QWebView":http://doc.qt.nokia.com/4.7/qwebview.html#QWebView ?

Hello i have write this c++:
@#include "widget.h"
#include "ui_widget.h"
#include <QWebView>

Widget::Widget(QWidget *parent) :
QWidget(parent),
ui(new Ui::Widget)
{
ui->setupUi(this);
connect(ui->pushButton, SIGNAL(clicked()), this, SLOT(apro_pagina()));
connect(&vista,SIGNAL(loadStarted()),this,SLOT(inizio_caricamento()));
connect(&vista,SIGNAL(loadProgress(int)),this,SLOT(stato(int)));
connect(&vista,SIGNAL(loadFinished(bool)),this,SLOT(finito(bool)));

}

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

void Widget::apro_pagina(){
vista.setHtml("test_page.html");
}

void Widget::inizio_caricamento(){
ui->label->setText("Inizio Caricamento");
}

void Widget::stato(int perc){
ui->label->setText(QString::number(perc));
}

void Widget::finito(bool vero){
ui->label->setText("Caricamento Finito");
vista.show();
}@

But when the widget is open i see only a white page with written inside test_page.html

What is wrong

Thanks
Luca

vista.setHtml() should have the HTML as argument, not the path to a file!

For a file, you should call load() with a QUrl as parameter (denoting the complete path to your html file).

Thanks for your time, now works

QDesktopServices::openUrl(QUrl("file:///C:/Documents and Settings/All Users/Desktop", QUrl::TolerantMode));

I guess you have checked already that the signals are triggered and that you are arriving the appropriate slots.

Have a look to the "previewer example":http://doc.qt.nokia.com/4.7/webkit-previewer.html
I guess your problem is
@
void Widget::apro_pagina(){
vista.setHtml("test_page.html");
}
@
I would have passed a string containing the web page content, but not the name of file with the content.
If you debug through the example, you should see what you have to pass.

Hi,

I see that the issue is already solved thanks to Volker but I want to advertise two very simple code snippets related to the topic that I have added lately to the wiki :)
"Open Web Page in QWebView":http://developer.qt.nokia.com/wiki/Open_Web_Page_in_QWebView
"How to launch Web Browser":http://developer.qt.nokia.com/wiki/How_to_Launch_Web_Browser

Cheers,
Leon
