errors:
mainwindow.cc: in member function ‘gtk::window* mainwindow::init()’:
mainwindow.cc:74:21: error: no matching function call ‘gtk::window::size_allocate()’
mainwindow.cc:74:21: note: candidate is:
/usr/include/gtkmm-3.0/gtkmm/widget.h:460:8: note: void gtk::widget::size_allocate(const allocation&)
/usr/include/gtkmm-3.0/gtkmm/widget.h:460:8: note: candidate expects 1 argument, 0 provided

im sure function call expecting parameter , hpaned should paned. use helping hand on one.

that function expects allocation object. tried google , had trash.
seems me have create or allocation object somehow.
more careful in api methods return allocation.
