Re: TreeView path and iter

["Paul Davis" <pjdavis engineering uiowa edu>]

John,

Not exactly sure about the functions you listed, but this is a simple
recursive function to find a given row.

bool
CellEventsModule::FindRow( int parent, Gtk::TreeModel::Children
children, Gtk::TreeModel::Row& row )
{
   if( children.empty() )
   {
       return false ;
   }

   Gtk::TreeModel::Children::iterator iter ;

   iter = children.begin() ;
   while( iter != children.end() )
   {
       if( (*iter)[ _event_columns.id ] == parent )
       {
           row = (*iter) ;
           return true ;
       }

       if( FindRow( parent, (*iter).children(), row ) )
       {
           return true ;
       }

       iter++ ;
   }

   return false ;
}

Its not the best, but it should get the idea acroos.
