示例1: add
void NoteHistory::add(Note note, int cursorPosition) {
if (!note.exists()) {
return;
}
NoteHistoryItem item(¬e, cursorPosition);
if (noteHistory->contains(item)) {
// decrease current index if we are going to remove an item before it
if (noteHistory->indexOf(item) < currentIndex) {
currentIndex--;
}
// remove found item
noteHistory->removeAll(item);
}
noteHistory->prepend(item);
if (currentIndex < lastIndex()) {
// increase current index
currentIndex++;
}
