You have to add "GB_HOOK_CHECK(xxxx)," to the class description, where 
"xxxx" is the name of a function declared that way:

int xxxx(void *object)
{
   // Return 1 if the Gambas object "object" is invalid,
   // and 0 if it is valid.
}

You have an example with CWIDGET_check() in the CWidget.cpp files of 
gb.gtk, gb.gtk3, gb.qt4 or gb.qt5.
