Grepping in gwenhywfar trunk, I see an implementation of GWEN_Gui_Print() in src/gui/gui.c that does nothing except return GWEN_ERROR_NOT_IMPLEMENTED, a declaration for same in the corresponding header, a comment in gui/qt4/qt4_gui.hpp: * @todo: @ref GWEN_Gui_Print() needs to be implemented, and one in gwenhywfar//src/gui/gui_be.h: * Please see @ref GWEN_Gui_Print for details. It's not called anywhere in Gwen code.

So maybe the button has a callback and your plan was to pass this function as the callback once you implemented it, and GnuCash can pass register its own print function for that callback. Where's the register function?
