Kai Koehne authoredQtDeclarative generates anonymous wrapper functions for QML bindings and slots, e.g. onPressed(): { i++ } becomes (function (onPressed) { i++ } ) v8 will by default break when the anonymous function is called, not when the actual code is executed. If we now hit this outer function we'll relocate the breakpoint to column = 1, and continue. Change-Id: Ieea4f4ea4fbf21d7245a6243fc36d141948ef2ce Reviewed-by:
