Thanks so much for taking a stab at it. I tried setting the experimental.preferredMinimumContentsWidth to numbers ranging from 1 to 10000, but it doesn't seem to have any sort of affect for me.
I have tried playing around with experimental.page.scale. I found setting it to 1200/webview.width gives something similar to what I'm looking for. It prevents the page from shrinking when resizing. However, everything ends up getting very blurry, so it can't be a solution for me.
I'll try digging through the experimental settings some more. It's too bad that it isn't better documented.
It is so sad that this zooming "feature" can't be turned off. It looks like QWebView behaves properly by default, but it is a Qt widget, not a Qt Quick widget. So I won't be able to use it in my application.
If anyone out there knows how to fix this, please help!
