How to make QML WebView Element use Qt::openUrlExternally instead of some visual newWindowComponent?

Answer 1

I don’t think there is a simple way to do this using QML. You can do this with the standard QWebView, but there isn’t a way to access this functionality from within QML. You would need to re-wrap QWebView and expose more functions.

An example using the standard C++ interfaces:

test.cpp

#include <QtGui>
#include <QtWebKit>
#include "handler.hpp"

int main(int argc, char** argv)
{
    QApplication app(argc, argv);

    QWebView view;
    view.load(QUrl::fromUserInput("http://qt-project.org/"));

    view.page()->setLinkDelegationPolicy(QWebPage::DelegateAllLinks);

    LinkHandler handler;

    QObject::connect(
        &view, SIGNAL(linkClicked(const QUrl&)),
        &handler, SLOT(open(const QUrl&)));

    view.show();

    return app.exec();
}

handler.hpp

#ifndef _HANDLER_HPP_
#define _HANDLER_HPP_

#include <QtGui>

class LinkHandler : public QObject
{
    Q_OBJECT
    public:
        LinkHandler();

    public slots:
        void open(const QUrl& url);
};

#endif

handler.cpp

#include "handler.hpp"

LinkHandler::LinkHandler() : QObject() {}

void LinkHandler::open(const QUrl& url)
{
    QDesktopServices::openUrl(url);
}
