<pre>While working on kinetic scrolling (<a class="bz_bug_link
bz_status_NEW "
title="NEW - [GTK] Add kinetic scrolling"
href="show_bug.cgi?id=155750">bug #155750</a>) I noticed that webkit doesnt have support for touch emulation on the view layer. Touch emulation is only supported in the WebCore layer (<a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - Implement touch event emulation in the WebCore layer"
href="show_bug.cgi?id=77105">bug #77105</a>), but the events there are not propagated to the view (only to the page), meaning testing things like kinetic scrolling (which requires touch events) wouldnt work without a real touchscreen device.
As I didnt have a touchscreen device available, I decided to add a basic support (single touch) for emulation on the view, by sending synthetic touch events when receiving mouse events. The impl uses the GTK_TEST_TOUCHSCREEN env variable to decide whether to enable emulation (as already done by other official GTK+ widgets).
While I believe this wont get integrated, I wanted to leave it here in case someone needs something similar in the future.
Patch to come.</pre>
