Call a function in a higher level class?

[JVene]

Some code or pseudo code would be useful here.

I'll try to surmise.

class Acct
{
 AcctTabs * m_tbctrl;
};

class AcctTabs
{
 AcctList * tabAcctList;
};

class AcctList
{
 Acct * acct;

 void func()
   {
     acct->UpdateNames();
   }
};

AcctList is a child of a child which needs to 'know' the parent of it's parent in order to make the call.

AcctList must therefore obtain a pointer to the appropriate instance of Acct, by whatever initialization path can be fashioned.

There must be some point where the m_tbctrl is set to the appropriate child. At that point, AcctTabs should probably obtain a pointer to it's parent.

Likewise, there must be some point where tabAcctList is set to it's child, and at that point the AcctList could receive it's parent.

class Acct
{
 AcctTabs * m_tbctrl;
};

class AcctTabs
{
 Acct *parent;
 AcctList * tabAcctList;
};

class AcctList
{
 AcctTabs *parent;
 Acct * acct;

 void func()
   {
     parent->parent->UpdateNames();
   }
};

Obviously this parent to parent is uncomfortable, but workable, so at the point where AcctList sets it's AcctTabs * parent, it could also obtain acct...

acct = parent->parent;
