     This function is only for use in widget implementations. Obtains
     'widget->requisition', unless someone has forced a particular
     geometry on the widget (e.g. with 'gtkWidgetSetSizeRequest'), in
     which case it returns that geometry instead of the widget's
     requisition.

_U_s_a_g_e:

     gtkWidgetGetChildRequisition(object)

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

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

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

     This function differs from 'gtkWidgetSizeRequest' in that it
     retrieves the last size request value from 'widget->requisition',
     while 'gtkWidgetSizeRequest' actually calls the "size_request"
     method on 'widget' to compute the size request and fill in
     'widget->requisition', and only then returns
     'widget->requisition'.

     Because this function does not call the "size_request" method, it
     can only be used when you know that 'widget->requisition' is
     up-to-date, that is, 'gtkWidgetSizeRequest' has been called since
     the last time a resize was queued. In general, only container
     implementations have this information; applications should use
     'gtkWidgetSizeRequest'.

_V_a_l_u_e:

     A list containing the following elements: 

'requisition': ['GtkRequisition']  a 'GtkRequisition' to be filled in

_A_u_t_h_o_r(_s):

     Derived by RGtkGen from GTK+ documentation
