Unofficial Mojo FAQ

ps: that opacity setting, assuming its an OS support, could be a good way to easily overlay the status window maybe ? the alternative is however the volume controls show up sometime (green bars on top of the screen)

It's easy to overlay an image. It's easy to make the overlaid image translucent. There are APIs in Windows that allow applications to do these things, and they have been in Windows for years.

The problems are (1) moving the overlay as fast as a cursor moves and (2) not creating visual artifacts as it moves.

If you're willing to hook DLLs and go outside the normal OS APIs, it's a different story. I assume that's what Innerspace does. But that's not practical for Mojo.

Edit: Or if you wrote your own device driver and manipulated video hardware directly -- I guess that's a theoretical possibility but it's not practical.

If I'm overlooking something, somebody please tell me!

I just realized, given the changes in Vista and Win 7, if the new DWM stuff is enabled and video card is present, these things may not be a problem anymore, especially in Win 7, especially with a fast video card.

I'll put a test implementation in Mojo so we can see.
