    <summary>Base class for widgets which contain other widgets</summary>
    <remarks>
      <para>
      A Gtk# user interface is constructed by nesting widgets inside widgets. <see cref="T:Gtk.Container" /> widgets are the inner nodes in the resulting tree of widgets: they contain other widgets. So, for example, you might have a <see cref="T:Gtk.Window" /> containing a <see cref="T:Gtk.Frame" /> containing a <see cref="T:Gtk.Label" />. If you wanted an image instead of a textual label inside the frame, you might replace the <see cref="T:Gtk.Label" /> widget with a <see cref="T:Gtk.Image" /> widget.
      </para>
      <para>
      There are two major kinds of <see cref="T:Gtk.Container" /> widgets in Gtk#. Both are subclasses of the abstract <see cref="T:Gtk.Container" /> base class.
      </para>
      <para>
      The first type of <see cref="T:Gtk.Container" /> widget has a single child widget and derives from <see cref="T:Gtk.Bin" />. These containers are decorators, which add some kind of functionality to the child. For example, a <see cref="T:Gtk.Button" /> makes its child into a clickable button; a <see cref="T:Gtk.Frame" /> draws a frame around its child and a <see cref="T:Gtk.Window" /> places its child widget inside a top-level <see cref="T:Gtk.Window" />.
      </para>
      <para>
      The second type of <see cref="T:Gtk.Container" /> can have more than one child; its purpose is to manage layout. This means that these containers assign sizes and positions to their children. For example, a <see cref="T:Gtk.HBox" /> arranges its children in a horizontal row, and a <see cref="T:Gtk.Table" /> arranges the widgets it contains in a two-dimensional grid.
      </para>
      <para>
      To fulfill its task, a layout <see cref="T:Gtk.Container" /> must negotiate the size requirements with its parent and its children. This negotiation is carried out in two phases, size requisition and size allocation.

          <para>
	  Typically used for simple containers such as <see cref="T:Gtk.Window" />, <see cref="T:Gtk.Frame" />, or <see cref="T:Gtk.Button" />; for more complicated layout containers such as <see cref="T:Gtk.Box" /> or <see cref="T:Gtk.Table" />, this function will pick default packing parameters that may not be correct. So consider functions such as <see cref="M:Gtk.Box.Packstart" /> and <see cref="M:Gtk.Table.Attach" /> as an alternative to <see cref="M:Gtk.Container.Add" /> in those cases. A <see cref="T:Gtk.Widget" /> may be added to only one <see cref="T:Gtk.Container" /> at a time; you can not place the same widget inside two different containers.

        <param name="evnt">an object of type <see cref="T:Gdk.EventExpose" /></param>
        <remarks>
          <para>
	  When a <see cref="T:Gtk.Container" /> receives an expose event, it must send synthetic expose events to all children that do not have their own <see cref="T:Gdk.Window" />s. This function provides a convenient way of doing this. A <see cref="T:Gtk.Container" />, when it receives an expose event, calls <see cref="M:Gtk.Container.PropagateExpose(Gtk.Widget,Gdk.EventExpose)" /> once for each child, passing in the event the <see cref="T:Gtk.Container" /> received.
	  </para>
          <para>
            <see cref="M:Gtk.Container.PropagateExpose(Gtk.Widget,Gdk.EventExpose)" /> takes care of deciding whether an expose event needs to be sent to the child, intersecting the event's area with the child area, and sending the event.
	  </para>
          <para>
	  In most cases, a <see cref="T:Gtk.Container" /> can either simply inherit the expose implementation from <see cref="T:Gtk.Container" />, or do some drawing and then chain to the expose implementation from <see cref="T:Gtk.Container" />.

        <remarks>
          <para>
	  In principle each <see cref="T:Gtk.Widget" /> in the chain should be a descendant of the <see cref="T:Gtk.Container" />, but this is not enforced by this method, since it is allowed to set the focus chain before you pack the widgets, or have a widget in the chain that is not always packed. The necessary checks are done when the focus chain is actually traversed.	   
	  </para>
          <para>
	  If no focus chain has been explicitly set, gtk# computes the focus chain based on the positions of the children. in that case, gtk# stores <see langword="null" /> in focusable_widgets and returns <see langword="false" />.
