如何检测Palm Pre上手势区域中的水龙头？

Question

Playing with my Palm Pre phone. I want to detect the user tapping in the gesture area (the area directly below the screen). How do I do that?

I haven't found anything obvious in the framework API's or service API's.

Answer 1

The gesture area is treated as the metaKey modifier on tap and key events. Listen for Mojo.Event.tap anywhere on the page, rest your finger on the gesture area, and then tap where you are listening. The event should have event.metaKey set to true .

Answer 2

I found this page, which describes capturing gesture-area inputs using the SDL_PollEvent method in the Plug-in Development Kit (PDK):

Unfortunately, I haven't figured out how to use the PDK yet...

Answer 3
