how do I look at class variables in debug mode? [message #760474]

I have a class which contains a pointer to a vector, the content of which I'd like to see, how can I do this in debug mode? I'm using indigo on ubuntu.

Use the Expressions view and add the name of the pointer you want to look at.

I went to expressions and clicked "add new expression", but I'm not familiar with the way expressions work. I tried to find documentation on this but it was either to broad or for java. Maybe you could get me started by providing a way of looking up the content of a vector pointed to in a class:

struct mystruct {
   vector<float> * vec // I want to know the content of this vector
}

Thanks!

If you declare variable

mystruct myvar;

you would then put in the expressions view:

myvar.vec

However, to see the content of a vector in nice readable format you need to enable pretty-printing:
