{
  mKeySplines.Clear();
  SetKeySplinesErrorFlag(PR_FALSE);
  mHasChanged = PR_TRUE;
}

Example #2

File: nsSMILAnimationFunction.cpp Project: houzhenggang/ExMail

void
nsSMILAnimationFunction::UnsetKeySplines()
{
    mKeySplines.Clear();
    SetKeySplinesErrorFlag(false);

}

Example #3

File: nsSMILAnimationFunction.cpp Project: lofter2011/Icefox

void

  if (!HasAttr(nsGkAtoms::keySplines)) {
    SetKeySplinesErrorFlag(PR_FALSE);
    return;
  }

  if (mKeySplines.Length() < 1) {
    // keyTimes isn't set or failed preliminary checks
    SetKeySplinesErrorFlag(PR_TRUE);
    return;
  }

  // ignore splines if there's only one value
  if (aNumValues == 1 && !IsToAnimation()) {
    SetKeySplinesErrorFlag(PR_FALSE);
    return;
  }

  // no. keySpline specs == no. values - 1
  PRUint32 splineSpecs = mKeySplines.Length();
