Bug 102790 – PageViewportControllerClient::didChangeViewportAttributes called twice

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit2

[Allan Sandfeld Jensen]

Both PageViewportController::updateMinimumScaleToFit and PageViewportController::didChangeViewportAttributes calls didChangeViewportAttributes on the PageViewportControllerClient, and since the former calls the later this means we end up firing didChangeViewportAttributes twice on the client.

wouldn't it be nicer if it returned a bool instead?

Perhaps. I am fine with either way.

I also think returning a bool indicating whether it updated the minimum size or not is the preferred pattern instead of a bool argument.

Maybe that should ahve IfNeeded() added?

I don't feel that is necessary for a method name starting with update, since update usually means to change something if needed.
