     Sets whether 'widget' should be mapped along with its when its
     parent is mapped and 'widget' has been shown with 'gtkWidgetShow'.

     gtkWidgetSetChildVisible(object, is.visible)

_A_r_g_u_m_e_n_t_s:

'object': ['GtkWidget']  a 'GtkWidget'

'is.visible': [logical]  if 'TRUE', 'widget' should be mapped along
          with its parent.

_D_e_t_a_i_l_s:

     The child visibility can be set for widget before it is added to a
     container with 'gtkWidgetSetParent', to avoid mapping children
     unnecessary before immediately unmapping them. However it will be
     reset to its default state of 'TRUE' when the widget is removed
     from a container.

     Note that changing the child visibility of a widget does not queue
     a resize on the widget. Most of the time, the size of a widget is
     computed from all visible children, whether or not they are
     mapped. If this is not the case, the container can queue a resize
     itself.

     This function is only useful for container implementations and
     never should be called by an application.
