Hi,
I'm quite new to Qt and am planning on using it for an upcoming project. I'm
currently just writing small test programs that implement each bit of
functionality I need before I throw myself into properly learning Qt, so
apologies if this is a bit of a newbie question.
I'm currently trying to get a webkit widget with a transparent background so
that if, in an HTML document, the html and body nodes are styled to have
their background-color set to transparent then the Widgets behind the
WebView Widget are visible through. I've had a play myself, browsed the API
documentation and done some searching and come up with a couple of things
but nothing has worked properly so far.
This is the code I have currently:
#include <QApplication>
#include <QWebView>
#include <QWebSettings>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QWidget window;
window.resize(1280, 720);
QWebSettings::globalSettings()->setAttribute(QWebSettings::DeveloperExtrasEnabled,
true);
QWebView *view = new QWebView(&window);
QPalette pal = view->palette();
pal.setBrush(QPalette::Base, Qt::transparent);
view->setPalette(pal);
// view->setAutoFillBackground(false);
// view->setAttribute(Qt::WA_OpaquePaintEvent);
view->load(QUrl("test.html"));
view->setGeometry(10, 10, 1260, 680);
window.show();
return app.exec();
}
and the HTML document I'm displaying:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "
http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;
charset=UTF-8" />
<title>Transparency Test</title>
<style type="text/css">
html,body,div,img {
background-color: transparent;
}
</style>
</head>
<body>
<h1>Hello World!</h1>
</body>
</html>
This does makes some bits transparent, unfortunately it also seems to make
the parent QWidget window transparent as well and just shows the console
window beneath the window. How do I go about making just the QWebView's
background transparent?
Thanks for any help,
Mike
