Yes and no :). The most confusing part of all this is that nothing has been set in stone, least of which the terminology. I believe Daniel is just noting the desired functionality, which will likely be implemented using "grabs". However, touch grabs may behave a little differently in that it will be possible to have tentative, not-for-you-yet touch events sent to multiple clients. -- Chase _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
