Querying Screen Capabilities in Windows

So how does one do this reliably? I have a dual monitor setup, with twin 1280x1024 monitors. CgScreen will only admit to one 1280x1024 monitor and CgDisplay only knows about one screen.

Re: Querying Screen Capabilities in Windows

Hi Tom,

What are the drawable dimensions for 'CgScreen default rootWindow'

I believe this is what I used for the code assist popup/multiple screen support.

Specifically, VAContentAssistPointRelativeLayout>>computePosition has logic

that gets the virtual screen size from the root window, which I believe creates one large logical desktop size that captures both your monitors.

It's been a while so some of the details are fuzzy, but see if that gets you anywhere.

And we have a winner! This gives me a drawableWidth of 2560 and a drawableHeight of 1024.

Thanks,
