Thank you for your help.
I am trying that, but haven't found the module pointer yet (in swmodule SwModule*) that needs to passed to RegisterControl(). Any ideas where to look for that?
And I intend to try first to put RegisterControl in reportdesign/source/ui/misc/toolboxcontroller.cxx, where the buttons are instantiated.
