vector declaration?

[Michael Sgier]

Hi
with:

dataStart = dbt.item[j].start;

i get that error:

src/Database/DBDatabase.cpp:272: error: request for member 'start' in
'((CDatabase*)this)->CDatabase::dbt.CDatabaseTemplate::item.
std::vector<_Tp, _Alloc>::operator[] [with _Tp = CDatabaseTemplateItem*,
_Alloc = std::allocator<CDatabaseTemplateItem*>](((long unsigned
int)j))', which is of non-class type 'CDatabaseTemplateItem*'

class CDatabaseTemplate {

//protected:
std::vector<CDatabaseTemplateItem* item; ///< Vector of template
items
actually i have start like that:

class CDatabaseTemplateItem {

public:
int start, end;

Why do i get an error? How should i declare/define start?
Thanks
Michael

Change

dataStart = dbt.item[j].start;

to

dataStart = dbt.item[j]->start;

Your vector is holding pointers. 'dbt.item[i]' return an element of
the vector, which is a pointer type, which is why you have to
dereference it.
