I'm pretty much new to palmos development.
I have a question about digitizer input. I've been reading the api manual and trying to get the idea but I haven't grasped it yet.
The thing is this: I want to be able to modify the digitizer input before it reaches any app, for example I want all programs (including the launcher) to ignore a specific spot on the screen. So I thought I should do a hack.
I know there are traps I can use like sysTrapEvtGetPen, but I want to understand if that will catch all pen input or only "lonely" strokes that don't get queued, and if there are other methods to get pen input besides the tipical GetPen. What are PenRawToScreen PenGetRawPen and PenOpen used for?
