[Avogadro-Discuss] can an Extension have a QDockWindow?

[B.W.H. v. B. <bw...@xs...>]

Hi,

I'm experimenting building a new extension for Avogadro. 
Is it possible to have for an extension a dockWindow(), just like the
"Tool Settings..." and "Display Settings" dock windows?
There is a virtual interface function

QDockWidget* Extension::dockWidget()

which, according to the documentation is supposed to return a list (?)
of  QDockWidgets , but I don't understand how I should use this  function.
Can somebody explain how this can be done?

Kind Regards,
Bertwim
