Hi guys, I am sending this mail to both xorg-devel and multi-touch-dev maillists just in case.
I've started using experimental XI 2.1 from Chase's personal ubuntu repository and noticed a few issues I would like to ask about: - I get XI_TouchMotion without ever getting XI_TouchBegin That happens with Apple Magic Trackpad when you move the mouse pointer out of the window, then touch the trackpad with one finger and move the pointer to the touch-enabled window. - Even worse - receiving XI_TouchBegin without ever getting XI_TouchEnd Just start touching over the window and then move the cursor outside of its boundaries. That screws up things for me as I have no way of knowing that touch sequence has ended. Is it a bug it intentional behavior? - Multiple XISelectEvents calls result in BadValue if you call XISelectEvents twice with the same mask value on XIAllDevices, it gives BadValue back. Currently in Qt with client-side widgets I do not store the information whether the widget has already selected touch events through the native toplevel and just always call XISelectEvent on the toplevel whenever a touch-aware widget appears. - What is the point of XI_TouchMask? It looks useless to me as I cannot use it in XISetMask as I would have expected. - Crash when disconnecting Magic Trackpad not that I care :) I don't have debugging symbols so can't give you the backtrace Chase, Daniel: would be nice to put packages with debugging symbols to the ppa. - Who is going to "adjust" valuators values for different devices? For example the Touch Minor and Touch Major valuators give me totally different values for N-Trig touch screen and for the Apple Magic Trackpad. On the N-Trig I usually get values around 400 for my finger pressing gently while the range is from 0 to 9600; while with the magic trackpad it is around 100 in the range 0 to 255. Another example is the MTAbsX valuator coming from the N-Trig - the range announced to be from 0 to 9600, while the value is actually in screen coordinates. Other than that it seems to be working fine and I am looking forward to having grabs implemented :) Awesome job guys! -- Best regards, Denis. _______________________________________________ Mailing list: https://launchpad.net/~multi-touch-dev Post to : multi-touch-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~multi-touch-dev More help : https://help.launchpad.net/ListHelp
