Hi Jocelyn,
Also, setting the following will make the WebView completely ignore any
viewport settings:
QQuickWebViewExperimental::setFlickableViewportEnabled(false);
But if I don't disable the flickable viewport, then mouse and touch clicks
(with the mouse) behave strangly - AND double-click will zoom.
hmmm... I guess I am back to some hack needed by deriving from
QQuickWebView and setting the zoom factor directly based on the
relationship between the width in the meta tag and the window width.
This seemed to work when using QWebView - but I still havent found the
equivalent for QQuickWebView:
void MainWebView::resizeEvent ( QResizeEvent * event )
{
QWebView::resizeEvent(event);
QWebPage::ViewportAttributes va =
page()->viewportAttributesForSize(page()->viewportSize());
qreal zf = ((qreal)width())/va.size().width();
setZoomFactor(zf);
}
br
