How to display a html page in qgraphicswebview

Hi,
I want to load a html page in qgraphicswebview.
How do I do it?

I tried with something like below
QString path = "/Users/user/Desktop/tocSample/learnONNav.html";
m_p_TB_WebView->setHtml(path);

but it didn't work out.

Kindly let me know how do I display the html in qgraphicswebview.

Thanks in advance

setHtml() accepts the HTML of the page, not its file path. Have a look at setUrl().

m_p_TB_WebView.load(QUrl("File:/Users/user/Desktop/tocSample/learnONNav.html");

I used something like this and the html page got load.
But on click on the hyperlinks on this page, it navigates to browser(IE/Chrome) and not on the graphicwebview.

Kindly let me know, how to make the hyperlink open on graphicwebview itself.

Thanks

This works fine for me:

Code:

#include <QtWidgets>
#include <QGraphicsWebView>
 
int main(int argc, char **argv) {
  QApplication app(argc, argv);
  QGraphicsView view;
  QGraphicsScene scene;
 
  view.setScene(&scene);
  QGraphicsWebView *wv = new QGraphicsWebView;
  scene.addItem(wv);
  view.show();
  wv->setUrl(QUrl("http://www.google.com"));
  return app.exec();
}

So does this:

Code:

#include <QtWidgets>
#include <QGraphicsWebView>
 
int main(int argc, char **argv) {
  QApplication app(argc, argv);
  QGraphicsView view;
  QGraphicsScene scene;
 
  view.setScene(&scene);
  QGraphicsWebView *wv = new QGraphicsWebView;
  scene.addItem(wv);
  view.show();
  QUrl url = QUrl::fromLocalFile(QFileInfo("page.html").absoluteFilePath());
  qDebug() << url.toString();
  wv->setUrl(url);
  return app.exec();
}

with page.html being:

Code:

<html>
<body>
        <div>Link: <a href="http://www.google.com">Google</a></div>
</body>
</html>

Re: How to display a html page in qgraphicswebview

Can somebody throw light on how to make use of setHtml() or setContent() for QGraphicsWebView.

setUrl() is making use of file from local machine.

I want it to take file from server or from anywhere else and not from local machine.

Added after 53 minutes:

void QGraphicsWebView::setContent ( const QByteArray & data, const QString & mimeType = QString(), const QUrl & baseUrl = QUrl() )

I hope this function will suit my need as it sets the content of qgraphicswebview from the html

Can someone provide a sample for this function.
I searched a lot on net but couldn't find any for qgraphicswebview.

How to load a .html file onto QGraphicsWebView?

I need to load a .html file onto QGraphicsWebView.
If it's from a local machine, I could directly use
SetUrl()

But I dont want it be loaded from local machine. I want it to be loaded from the server or elsewhere.
How can this be done in Qt.

Thanks in Advance.

You already know: setUrl()

So pass a URL of the file on the server.
