The code i was using already made use of those methods. However, i could go
down no further than the root level. I am wondering how to obtain the children
for the keys i've only been able to get. Here's is the current, relevant part
of the code i am using:
//
{
QList<DSword::TreeNode> sectionsList;
sword::TreeKey *tk = dynamic_cast<sword::TreeKey*>(swModule->getKey());
if (tk->firstChild())
{
while (tk->nextSibling())
{
DSword::TreeNode node;
node.name = tk->getText();
node.parent = NULL;
sectionsList << node;
}
}
return sectionsList;
}
//
Let's say i load the English GenBook, "Immitation." I only get the following:
/Foreword
/Book 1
/Book 2
/Book 3
/Book 4
though the last four have children. Trying to figure out how to obtain the
children through trial and error have so far led me no where.
