Unable to view .ico file format about qview

Not sure how useful this is but opening the .ico files in Firefox results in the highest quality being displayed. The best outcome would be something similar to how Preview on MacOS shows all the various quality versions of the .icns format.

Also, your fix totally works. Thanks!

@jurplel This happens when "Image scaling" is enabled (or even when it's not, if invoking "Original size"). The problem is, currentFileDetails.isMovieLoaded is true even though it ends up not being a valid movie. Although QMovie::isValid initially returns true, QMovie::start fails and causes QMovie::isValid to start returning false. QMovie::state also returns QMovie::MovieState::NotRunning when this happens. This fixes it for me.

As for picking the highest resolution image, I couldn't figure out how to do it. QImageReader::imageCount returns more than one, but I didn't have any luck loading anything other than the first, whether it was by calling QImageReader::read repeatedly, QImageReader::jumpToNextImage, or QImageReader::jumpToImage.
