Include help for libstdc into QtCreator

th.thielemann

I use doxygen style to document my c++ code. And for the different libraries I create .qch files to see the documentation within QtCreator. The used doxygen tags are:
GENERATE_QHP = YES
QCH_FILE = Mylib.qch
QHP_NAMESPACE = MyLibrary
QHP_VIRTUAL_FOLDER = doc
QHP_CUST_FILTER_NAME =
QHP_CUST_FILTER_ATTRS =
QHP_SECT_FILTER_ATTRS =
QHG_LOCATION = /usr/bin/qhelpgenerator

And if I select an item from my lib in sourcecode an press F1, the related documentation is shown. I tried the same for the libstdc. But if I select methods from eg. std::list I do not get any output or output for QML's list.
What do I'm wrong here?
