示例1: showPopup
void RenderMenuList::showPopup()
{
if (m_popupIsVisible)
return;
if (document()->page()->chrome().hasOpenedPopup())
return;
// Create m_innerBlock here so it ends up as the first child.
// This is important because otherwise we might try to create m_innerBlock
// inside the showPopup call and it would fail.
createInnerBlock();
if (!m_popup)
m_popup = document()->page()->chrome().createPopupMenu(this);
m_popupIsVisible = true;
// Compute the top left taking transforms into account, but use
// the actual width of the element to size the popup.
FloatPoint absTopLeft = localToAbsolute(FloatPoint(), UseTransforms);
IntRect absBounds = absoluteBoundingBoxRectIgnoringTransforms();
absBounds.setLocation(roundedIntPoint(absTopLeft));
HTMLSelectElement* select = selectElement();
m_popup->show(absBounds, document()->view(), select->optionToListIndex(select->selectedIndex()));
