pointers in c++

[:db:sStrong]

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

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();
 
			}
		}

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();

			}
		}

To copy to clipboard, switch view to plain text mode 

and this the declaration of the pointer

CHL m_pHL;

CHL m_pHL;

To copy to clipboard, switch view to plain text mode 

Can someone tell what i am doing wrong?
