Problem regarding C++ STL

[vermarajeev]

Hi guys,
I'm working on a project where I need to remove Qt libraries and use C++ STL.
I need to replace QPtrList::findRef defined in Qt with C++ STL alternative . But unable to get any solution.

For example
I have used STL's find(InputIterator first, InputIterator last, const T& value) to replace QPtrList::find. The code can be seen as below

Defined in Qt3

if( -1 == steps.find( s ) )

if( -1 == steps.find( s ) )

To copy to clipboard, switch view to plain text mode 

Alternative in C++ STL

StepListIterator sIt = find( steps.begin(), steps.end(), s);
if (sIt == steps.end())
 { 
    //not found perform relevant operation
 }

StepListIterator sIt = find( steps.begin(), steps.end(), s);
if (sIt == steps.end())
 { 
    //not found perform relevant operation
 }

To copy to clipboard, switch view to plain text mode 

Similar way I need to replace Qt's QPtrList::findRef with an C++ STL alternative.
Please help me

Waiting for your reply

Thankx in advance
