Subject: Use QMetaObjectPrivate::signalOffset() where appropriate
X-Git-Tag: 071012110112~629
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0d86ca432ae39574dd644de1ebc73597a2e43974;hp=e051819983bc6625f8c3f4b8158cb67c2bd8dd52;p=profile%2Fivi%2Fqtbase.git

Use QMetaObjectPrivate::signalOffset() where appropriate

computeOffsets() was unnecessarily computing the method index, when
only the signal index is needed.
