Which window receives input?

[kylekc@umich.edu]

Hi, I'm trying to develop a touch screen controls overlay to play Dolphin on a touch screen computer, and I'm doing this in C#. Basically, I need to send a key press message to one of Dolphin's windows where it will be processed as a keyboard input. The problem is, Spy++ shows me at least a dozen different windows under the Dolphin process, and I have no idea which one listens for the input. Does anyone know how I can proceed?

Additionally, if anyone is aware of another option for what I'm trying to accomplish, I'd love to hear it!

Maybe this is a good time to implement this feature much close to the dolphin Core, so we can make this code shared with the Android UI.
