示例1: maybeTip
/**
* Displays a tool-tip according to the current location of the mouse
* pointer.
* @param pt The mouse pointer coordinates
*/
void ListToolTip::maybeTip(const QPoint& pt)
{
QString str;

// Get the item at the given point
pList = m_pList->getList();
pItem = pList->itemAt(pt);
if (pItem == NULL)
return;
// Get the tip string for this item
if (!m_pList->getTip(pItem, str))
return;
// Get the bounding rectangle of the item
const QRect rcItem = pList->itemRect(pItem);
if (!rcItem.isValid())
return;
// Get the header coordinates
const QRect rcHead = pList->header()->rect();
if (!rcHead.isValid())
return;
// Calculate the tool-tip rectangle
QRect rcCell(rcHead.left(), rcItem.top(), rcItem.width(), rcItem.height());
// Display the tool-tip
