I don't understand why we would need to modify the declaration of NPTouchEvent::points to be of type OwnArrayPtr. Can't we just define a local variable in this function of type OwnArrayPtr<NPTouchPoint> called touchPoints. Then set npTouchEvent.points = touchPoints.get() and remove "delete[] npTouchEvent.points" (line 559). The code would have the following form: ... OwnArrayPtr<NPTouchPoint> touchPoints; unsigned numberOfTouchPoints = touchList->length(); if (numberOfTouchPoints) { touchPoints = adoptArrayPtr(new NPTouchPoint[numberOfTouchPoints]); for (unsigned i = 0; i < numberOfTouchPoints; ++i) { Touch* touchItem = touchList->item(i); touchPoints[i].touchId = touchItem->identifier(); ... touchPoints[i].pageY = touchItem->pageY(); } } npTouchEvent.points = touchPoints.get(); NPEvent npEvent; npEvent.type = NP_TouchEvent; npEvent.data = &npTouchEvent; if (dispatchNPEvent(npEvent)) { ... } else if (npTouchEvent.type == TOUCH_EVENT_DOUBLETAP) { ... } > Source/WebCore/plugins/blackberry/PluginViewBlackBerry.cpp:1070 > + default: > + return false; > + } NPNVariable is an enum type. Instead of having a default statement we should list all of the other enums values here and fall through to a return false, like: case NPNVxDisplay: case NPNVxtAppContext: ... case NPNVprivateModeBool: return false; Then add an ASSERT_NOT_REACHED() after the switch statement and "return false;". By using this approach we'll get a compiler error should someone define a new enum value in NPNVariable. > Source/WebCore/plugins/blackberry/PluginViewBlackBerry.cpp:1158 > + default: > + return platformGetValueStatic(variable, value, result); > + // FIXME: Should we return false? > + } We should use a similar approach here. 520616 11 119141 charles.wei 2011-12-13 19:40:56 -0800 Created attachment 119141 Patch 520724 12 119167 charles.wei 2011-12-13 23:35:59 -0800 Created attachment 119167 Patch V5 Resubmit the patch and set the review flag and commit-queue flag. 520908 13 119167 tonikitoo 2011-12-14 07:02:15 -0800 Comment on attachment 119167 Patch V5 View in context: https://bugs.webkit.org/attachment.cgi?id=119167&action=review Looks good to me. > Source/WebCore/plugins/blackberry/PluginViewBlackBerry.cpp:680 > + // Clip against any frames that the widget is inside.
