Passing a path to the QUrl constructor is wrong. This could be done with KUrl, \
but here you should use QUrl::fromLocalPath("/home/test/"), to avoid getting invalid \
QUrl objects.
Moreover, if do replace the manual slash search with KIO::upUrl, as I suggested \
in the other comment, then you might have to add trailing slashes to all paths in the \
test.
src/urlutil.h (line 60)
<https://git.reviewboard.kde.org/r/123253/#comment62939>
Instead of messing around manually with the slashes, you could use KIO::upUrl(), \
something like
QUrl firstChildUrl(const QUrl& lastUrl, const QUrl& currentUrl)
{
if (!currentUrl.isParentOf(lastUrl)) {
return QUrl();
}
QUrl childUrl = lastUrl;
QUrl parentUrl = KIO::upUrl(childUrl);
while (parentUrl != currentUrl) {
// childUrl is not the first child URL yet.
childUrl = parentUrl;
parentUrl = KIO::upUrl(childUrl);
if (!currentUrl.isParentOf(childUrl)) {
// Not sure if this can happen, but better prevent an infinite \
loop if there is // a bug in KIO::upUrl().
return QUrl();
}
}
return childUrl;
}
