示例1: while
void QGLIndexBufferPrivate::append
(const QGLIndexBufferPrivate *other, uint offset, int start)
{
if (elementType == GL_UNSIGNED_SHORT &&
other->elementType == GL_UNSIGNED_SHORT) {
// Both buffers are ushort.
const ushort *data = other->indexesShort.constData() + start;
int count = other->indexesShort.count() - start;
indexesShort.reserve(indexesShort.count() + count);
indexCount += count;
while (count-- > 0)
indexesShort.append(ushort(*data++ + offset));
} else if (elementType == GL_UNSIGNED_SHORT) {
// Only first buffer is ushort: convert it to int first.
const ushort *indexes = indexesShort.constData();
int count = indexesShort.count();
indexesInt.reserve(count + other->indexesInt.count());
while (count-- > 0)
