point / STL vector, change element question

true_atlantis · 09-17-2005, 01:25 PM

ok, i have a STL vector of type cadElement, where cadElement is a struct...

Code:

struct cadElement{
  int cad_type;
  int cad_pick;
  double cad_x;
  double cad_y;
  double cad_z;
  double cad_r;
  double cad_g;
  double cad_b;
  double cad_zoom;
};
vector<cadElement> elements;

how can i change a value of one of the elements in the vector??

Code:

((cadElement)elements.at(1)).cad_x=x;

does not work, it will not change the value in the actual vector...

You could use the subscript operator:

Code:

elements[0].cad_x = x;

Just make sure there's actually an instance of the struct at the given index.
