示例1: Serialize
void
nsTreeContentView::SerializeItem(Element* aContent, int32_t aParentIndex,
int32_t* aIndex, nsTArray<UniquePtr<Row>>& aRows)
{
if (aContent->AttrValueIs(kNameSpaceID_None, nsGkAtoms::hidden,
nsGkAtoms::_true, eCaseMatters))
return;
aRows.AppendElement(MakeUnique<Row>(aContent, aParentIndex));
Row* row = aRows.LastElement().get();
if (aContent->AttrValueIs(kNameSpaceID_None, nsGkAtoms::container,
nsGkAtoms::_true, eCaseMatters)) {
row->SetContainer(true);
if (aContent->AttrValueIs(kNameSpaceID_None, nsGkAtoms::open,
nsGkAtoms::_true, eCaseMatters)) {
row->SetOpen(true);
nsIContent* child =
nsTreeUtils::GetImmediateChild(aContent, nsGkAtoms::treechildren);
if (child && child->IsXULElement()) {
// Now, recursively serialize our child.
int32_t count = aRows.Length();
int32_t index = 0;
Serialize(child, aParentIndex + *aIndex + 1, &index, aRows);
row->mSubtreeSize += aRows.Length() - count;
}
else
row->SetEmpty(true);
} else if (aContent->AttrValueIs(kNameSpaceID_None, nsGkAtoms::empty,
nsGkAtoms::_true, eCaseMatters)) {
row->SetEmpty(true);
}
}
}示例2: RemoveSubtree
void
nsTreeContentView::CloseContainer(int32_t aIndex)
{
Row* row = mRows[aIndex].get();
row->SetOpen(false);
int32_t count = RemoveSubtree(aIndex);
if (mBoxObject) {
mBoxObject->InvalidateRow(aIndex);
mBoxObject->RowCountChanged(aIndex + 1, -count);
}
}示例3: EnsureSubtree
void
nsTreeContentView::OpenContainer(int32_t aIndex)
{
Row* row = mRows[aIndex].get();
row->SetOpen(true);
int32_t count = EnsureSubtree(aIndex);
if (mBoxObject) {
mBoxObject->InvalidateRow(aIndex);
mBoxObject->RowCountChanged(aIndex + 1, count);
}
