So a couple of questions arise. Would it be possible to have the entire source code? We are ready to sign an NDA or any other contract if necessary. I am asking this because I am having difficulties to imagine how we could make the changes without being able to check how it works in the program. If there is a way to do it rapidly then of course we won't need the entire code source.
The library that handles the touch events (touchDown, touchUpdate, touchRemove) is written in C++ (would wrap it of course). It gives basically the coordinates of the touches and updates the coordinates when dragging the finger. So we would need to replace mouse events with those and make zooming, translating and rotating functions available by using only the fingers. We would also make a new menu bar with only a couple of functions to be able to demonstrate the concept.
Hi, I implemented a multi-touch interface using the iPhone controller Chimera. For what you're describing, you don't need the C++ source code, just the Python code. Here's what I did. I embedded a threaded web server in Chimera using the standard Extension mechanism. That web server receives external multi-touch interface events and converts them to Chimera Python code. In your case, you would wrap your C++ event library in Python instead of using a web server. Here's an example when touch info comes in. RecordPosition gets called when a user presses down on the iPhone. TranslateXYCommand gets called when user drags 1 finger. ScaleXYCOmmand gets called when user pinches or expands two fingers. elif isinstance(item, RecordPositionCommand): chimera.viewer.recordPosition(time.time(), int(item.x), int(item.y), None) elif isinstance(item, TranslateXYCommand): chimera.viewer.translateXY(int(item.x), int(item.y), False) elif isinstance(item, ScaleXYCommand): chimera.viewer.zoom(int(item.x), int(item.y), False) Dave
