Bug 127760 – Change a logic for touching slider in "RangeInput::handleTouchEvent"

• Component: WebKit EFL
• Status: NEW

[Byung Jun Kim]

If we touch slider and other side ,It weren't recognized as multi touch.
So change "TargetTouches" to "touches" in RangeInput::handleTouchEvent.

This is in non-iOS code, so I probably won't be the final reviewer, but why would you want to change from targetTouches to touches here?

Could you try to better describe the scenario you're fixing? I am having trouble understanding your comment in the ChangeLog.

In slider, nomal operation of Multi touch is changed from first touch.
So, thumb of slider should move only first touch.
But, If we touch thumb first and track second, slider moves from second touch.
Thumb and track is not same target. It isn't recognized multi touch because of "TargetTouch"
So we should change "touch" to "targetTouch".

You'd better redescribe the change log as the sentences are not grammatical and it is hard to understand.

If we touch thumb and track, slider should move from first touch. 
In current, slider is changed by second touch because of "targetTouches"
Thumb and track is not same target. So it isn't recognized multi touch.
So we should change "targetTouches" to "touches".

I don't still understand this description. So, I'm not 100% sure if my change is correct though, I modify this description as below,

When we touch thumb or track widget, *slider* on the thumb or track widgets is moved by first touch. However the slider under current implementation is worked by second touch. Because the slider is influenced by targetTouches() function as well. However, thumb and track widgets aren't same target widget, so those aren't able to be recognized by multiple touches. To fix this problem, we need to use *touches()* function instead of the *targetTouches()*
