示例1: targetContent
nsresult
nsImageMap::HandleEvent(nsIDOMEvent* aEvent)
{
nsAutoString eventType;
aEvent->GetType(eventType);
bool focus = eventType.EqualsLiteral("focus");
NS_ABORT_IF_FALSE(focus == !eventType.EqualsLiteral("blur"),
"Unexpected event type");
//Set which one of our areas changed focus
nsCOMPtr<nsIDOMEventTarget> target;
if (NS_SUCCEEDED(aEvent->GetTarget(getter_AddRefs(target))) && target) {
nsCOMPtr<nsIContent> targetContent(do_QueryInterface(target));
if (targetContent) {

for (i = 0; i < n; i++) {
Area* area = mAreas.ElementAt(i);
if (area->mArea == targetContent) {
//Set or Remove internal focus
area->HasFocus(focus);
//Now invalidate the rect
if (mImageFrame) {
nsRect dmgRect;
area->GetRect(mImageFrame, dmgRect);
mImageFrame->Invalidate(dmgRect);
}
break;
}
}
}

}示例2: nsRect
nsresult
nsImageMap::GetBoundsForAreaContent(nsIContent *aContent,
nsRect& aBounds)
{
