I gave a go to #2, and effectively we can't get too far with it nowadays. Even if GTK+ itself can be made to work reasonably, the vast majority of applications have done nothing wrt the adoption of GDK_TOUCH_MASK or GtkGesture, which causes major regressions on touch all around. I won't dare go that way until the adoption of GtkGesture is wider (or is the canonical way to handle input), so I'm attaching a patch that goes along the lines of the current one. It will enforce crossing events when the user switches between real and emulated pointer events, and only if these lie on different windows. This makes the balance of enter and leave events right on the GDK side. NB, The mutter patches from <a class="bz_bug_link bz_status_NEW " title="NEW - Only pointer serials are compared when popping up a window" href="show_bug.cgi?id=756296">bug #756296</a> are also needed so you can trigger the popup through touch, in addition to being able to operate with it afterwards.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
