[SOLVED] Automatic children freeing for objects derived from QObject

[jacek]

will QT handle this itself when "destructing" the parent QTreeWidget?

Yes, it will:

#include <QObject>
#include <QtDebug>
 
class Test : public QObject
{
   public:
      Test( QObject * parent = 0 ) : QObject( parent ) { qDebug() << "Test::Test()"; }
      ~Test() { qDebug() << "Test::~Test()"; }
};
 
int main()
{
   Test *t1 = new Test();
   Test *t2 = new Test( t1 );
 
   delete t1;
 
   return 0;
}

#include <QObject>
#include <QtDebug>

class Test : public QObject
{
   public:
      Test( QObject * parent = 0 ) : QObject( parent ) { qDebug() << "Test::Test()"; }
      ~Test() { qDebug() << "Test::~Test()"; }
};

int main()
{
   Test *t1 = new Test();
   Test *t2 = new Test( t1 );

   delete t1;

   return 0;
}

Result:

Test::Test()
Test::Test()
Test::~Test()
Test::~Test()
