This can be implemented using different animation equations to control the speed of the animation. See:<br><br><a href="http://www.robertpenner.com/easing/">http://www.robertpenner.com/easing/</a><br><br>Ryan<br><br><div><span class="gmail_quote">

<br>><br>> Thank you. I added your report to the wiki, and reorganized the mails<br>> so that a human being can try to contribute :p<br>><br>> <a href="http://wiki.openmoko.org/wiki/UI_Improvements">http://wiki.openmoko.org/wiki/UI_Improvements
</a><br>> Please take a look if interested to help.<br>><br>> If you have some spare time to continue reporting about the<br>> touchscreen, there are some questions on the wiki, but anybody having<br>> access to hardware can do it.
<br>><br>> Why do i keep asking for this? Because i'm not sure apple's ibooks<br>> have multi-touch pads, but if you slide 2 fingers in parallel, it<br>> makes scrolling. Which means: if it's not multitouch at it's base
<br>> (and, if it was, there would be more of it), then they detect it using<br>> a hack. So can we do too, but we have to know exactly how the<br>> touchscreen reports "exotic" uses.<br><br>The synaptics touchpad driver for X supports 2- and 3-finger taps but requires
<br>hardware support for this. The apple touchpad appears to be a variant on this<br>(see <a href="http://www.popies.net/atp/">http://www.popies.net/atp/</a>). I've never tried a 2-finger drag on my<br>synaptics pad so I don't know what it would do.
<br><br>Of course the apple/synaptics pad may have a similar hack in firmware, so the<br>questions are still valid.<br><br>><br>> Regards<br>><br>> Florent<br>><br>> _______________________________________________
