Detailed Description

The QWebPage.ViewportAttributes class describes hints that can be applied to a viewport.

QWebPage.ViewportAttributes provides a description of a viewport, such as viewport geometry, initial scale factor with limits, plus information about whether a user should be able to scale the contents in the viewport or not, ie. by zooming.

ViewportAttributes can be set by a web author using the viewport meta tag extension, documented at Safari Reference Library: Using the Viewport Meta Tag.

All values might not be set, as such when dealing with the hints, the developer needs to check whether the values are valid. Negative values denote an invalid qreal value.
