How to set resolution higher on Flex desktop native (Air) app?

问题

I'm trying to change the resolution for a flex native app (air) app running on a retina macbook. Flex apps in the browser render everything smoothly at 160dpi automatically but if I build the same app as Air install app, it renders at 72dpi and doesn't look as good. I know you can set a resolution in the application descriptor file for a mobile app but this isn't one. Also, I've tried setting the applicationDPI property on the WindowedApplication tag as well with no luck. Any ideas? Thanks...

回答1:

For the record, to enable high resolution rendering in AIR desktop apps running on e.g. Retina Macbook Pros, set <requestedDisplayResolution>high</requestedDisplayResolution> in the <initialWindow> part of your app descriptor XML. Requires Adobe AIR 3.6 or newer.

to scale the app based on the user’s resolution. Here’s the code:
