I'm getting pressure 1 when pressed and 0 when released on a touchscreen. Many touchscreens don't offer pressure valuators. If you are getting -1 I think that's a bug. What kind of touch hardware are you using? Since you mentioned the tablet example, maybe it's an Intuos 5 or something like that? We hope to support it eventually; I'm trying to acquire one for testing. > Why?! because Qt5 removed X11 and Xi relatived part? > https://github.com/krre/AprilBrush-Desktop/blob/master/cpp/wacom/wacom_unix.cpp#L31 We've been adding functionality, but Xi2 is different than Xi1 which Qt 4 was using. It is not allowed to use both APIs... they're quite incompatible. Xi1 is obsolete; we need to use Xi >= 2.2 in order to have multi-touch support at all. So now it seems there is more work to be done to get the Intuos touch support working correctly with Xi2.
