QT WebKit with WebGl not Working with Qt 5.2

[Viraj Bhatt]

Hi All,

I have to developed sample application to see webGL supported to Qt webKit,

I want to know that, can we open webGL on QT WebKit with QT 4.8.4 or upper QT Version?

if yes, can you guide how to configure QT Webkit and How to build a same?

Thanks

"Not working" is hardly a good description of anything.

Official Qt 5.2.0 binaries on 64-bit Linux with this code:

#include <QApplication>
#include <QWebView>
 
int main(int argc, char **argv) {
    QApplication app(argc, argv);
    QWebView view;
    view.setUrl(QUrl("http://www.webkit.org/blog-files/webgl/SpiritBox.html"));
    view.show();
    return app.exec();
}

#include <QApplication>
#include <QWebView>

int main(int argc, char **argv) {
    QApplication app(argc, argv);
    QWebView view;
    view.setUrl(QUrl("http://www.webkit.org/blog-files/webgl/SpiritBox.html"));
    view.show();
    return app.exec();
}

To copy to clipboard, switch view to plain text mode 

work just fine. (Actually exiting the program is causing issues but the web component does work)

Looks like you do not have suitable OpenGL libraries present on your system.
