How to display a html page in qgraphicswebview

**ejoshva** · 9th February 2015, 06:29

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:

Qt Code:

Switch view

#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();
}

#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();
}

To copy to clipboard, switch view to plain text mode

So does this:

Qt Code:

Switch view

#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();
}

#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();
}

To copy to clipboard, switch view to plain text mode

with page.html being:

html Code:

Switch view

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

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

To copy to clipboard, switch view to plain text mode

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.

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()

By setUrl() , I am able to load the .html from local machine.
I want to the load the .html file from server and not local machine.

So pass a URL of the file on the server.
