pointers in c++

Hello folks

I have a simple question regarding pointers. I have a programe which should make some of the items of a qlistview bold. I have declared a pointer to the class where i have functions who can distinguish which items should be bold. But the crashes on that pointer.

Here is my code

Code:

---

pItem->bold = false;
 
		if (pItem->m_pHL)
		{
 
	// programe crashes here		if (pItem->m_pHL->STestt()->IsTested())
			{
				pItem->bold = true;
				pItem->setOpen(true);
			}
 
			QListViewItem *p = pItem->parent();
 
			while(p)
			{
				((CTestViewItem*)p)->bold = true;
				p = p->parent();
 
			}
		}

---

and this the declaration of the pointer

Code:

---

CHL m_pHL;

---

Can someone tell what i am doing wrong?

There are several possibilities.

* pItem->m_pHL is a dangling pointer. This means it once pointed to something which is deleted by this point. When you dereference (->) it, the program crashes.

* pItem->m_pHL->STestt() is a dangling pointer.

* pItem->m_pHL->STestt() is NULL.
