1) tick in Settings->GDB/CDB debugger->Default->Evaluate expression under cursor
2) Create a project with this source for example:
#include <iostream>
using namespace std;
struct test {
int a;
double b;
};
int main()
{
cout << "Hello world!" << endl;
test t;
t.a = 1;
t.b = 1.1;
cout << t.a << endl << t.b << endl;
return 0;
}
3) place a breakpoint in the line before return.
4) Start debugging
5) Hover with the mouse over one t element
6) The popup of cc and dbg will kick in an overriede each other.
With this example it is quite hard to reproduce, because cc is probably to fast. I have attached a screenshot for example.
