The attached patch addresses this bug. The idea is to leave the TOC
(e.g.) open when closing one buffer, if there is still one open.
This seems slightly dangerous, so I won't push to commit this now,
though if people think it's a good idea and it seems safe, then we
could. For what it's worth, there is nearly identical code in
LyXFunc::closeBuffer():
void LyXFunc::closeBuffer()
{
// goto bookmark to update bookmark pit.
for (size_t i = 0; i < LyX::ref().session().bookmarks().size(); ++i)
gotoBookmark(i+1, false, false);
if (theBufferList().close(lyx_view_->buffer(), true) && !quitting) {
if (theBufferList().empty()) { //NOTE THIS LINE
// need this otherwise SEGV may occur while
// trying to set variables that don't exist
// since there's no current buffer
lyx_view_->getDialogs().hideBufferDependent();
} else {
lyx_view_->setBuffer(theBufferList().first());
}
}
}
So I doubt the attached patch could cause any problems that aren't
already here. So if anyone thinks it's good for 1.5.0, let me know.
