I don't know how this is made with wxWindows, but in
GIO for Port the container for the button is specified
as argument to "button" function. Once created the
button cann't change its parent. I the trouble here is
with "layout" attribute. Its setter should chech when
all widget inside the Layout data are assigned to the
target widget. I suppose that with wxWindows the case
is similar with the Port.
