C++ (Cpp) setCurveColor Examples

Example #1

void KstQuickPSDDialogI::changeColor() {
  QColor c;
  c = curveColor();
  if ((int)KColorDialog::getColor(c) == (int)KColorDialog::Accepted ) {
    setCurveColor(c);
  }
  _curveAppearance->setColor(c);
}

Example #2

File: bspline.cpp Project: weidongguo/ecs175_computer_graphics

Bspline::Bspline(Graph *_graph, Point_2D *_ctrlPoints, int _numberOfCtrlPoints, int _k, float *_knotValues)
:Curve(_graph, _ctrlPoints, _numberOfCtrlPoints)
{
  k = _k;
  knotValues = new float[_numberOfCtrlPoints + _k];// n+1+k
  memcpy(knotValues, _knotValues, sizeof(float)*(_numberOfCtrlPoints+_k));
  setCurveColor(COLOR_CRIMSON);
  knotValuesCap = _numberOfCtrlPoints +_k;
}
