Thank you for the suggestion. However, this kind of feature in non-trivial since you’d have to stream-back the drawn data (in the desktop application) to the tablet. This whould cause very much network overhead and also it would be laggy drawing too. You’re not alone with your wish. We’ve often heard this request already, but I’m sorry to say that it will not come to gfxtablet for a while…
Many thanks for your very prompt response. However, I didn’t mean that GfxTablet should stream-back the drawn data to the tablet - what would be drawn on the tablet would just help in locating already drawn letters (resp. lines, curves) on screen ; having exactly the same drawing/image/figure on the computer and on the tablet is not needed ; respecting colors (say) would be nice, but not necessary. The simplest way would be to have an option that stylus displacement (when appled on tablet) would draw a segment between consecutive position events on the tablet, that’s it, so the only cost in time would be sending a call to the SurfaceFlinger widget on Android, that’s it - (possibly additionally enlarging the protocol to include “new color” events, optionally, but this is not a real priority for me …)
I enclose here a very simple app I am developping on my linux box to make white board presentations (righ now, either with a wacom tablet “blindly”, or with a Boogie Board - much more satisfactory, as the Boogie board actually draws what you are writing ; this small enhancement in GfxTablet would allow doing the same with the Galaxy Note).
