Dynamic structure error

AlvaroS

Hi to all.
First of all thank for helping me and reading this post.

I am trying to create a dynamic structure.
My code is:

Header:

typedef struct { //We define the line structure
    std::double_t x_start;
    std::double_t x_end;
    }struc_lines;

private
    std::vector<struc_lines> lines_struct;

Now I would like to add x_start and x_end to the structure which we do not know the size (so because of that it is a dynamic structure).

I have tried with

 lines_struct[i].y_start=(1.25); //For example

It compiles fine but it does not work.
How can I use .push_back for example in lines_struct.x_start???

Thanks a lot.

Hi
You mean

struc_lines Line;
Line.x_start=100;
lines_struct.push_back(Line);

Now it has 1 entry so
QDebug() << lines_struct[0].x_start;
should give 100.
