    <title>Useful methods for a Grid widget</title>

    <list>
      <item><p>To attach a widget <code>child</code> in position <code>left, top</code> in a slot of given <code>width, height</code> use <code>attach(child, top, left, width, height)</code>. If a widget <code>sibling</code> is already in place, we can also use <code>attach_next_to(child, sibling, side, width, height)</code>, where <code>side</code> is one of <code>Gtk.PositionType.LEFT, Gtk.PositionType.RIGHT, Gtk.PositionType.TOP, Gtk.PositionType.BOTTOM</code>.</p></item>
      <item><p><code>insert_row(position)</code> and <code>insert_column(position)</code> do exactly what they say; children which are attached at or below this position are moved one row down, and children which span across this position are grown to span the new row. <code>insert_next_to(sibling, side)</code> inserts a row or column at the specified position. The new row or column is placed next to <code>sibling</code>, on the side determined by <code>side</code>; if side is <code>Gtk.PositionType.TOP</code> or <code>Gtk.PositionType.BOTTOM</code>, a row is inserted, if side is <code>Gtk.PositionType.LEFT</code> or <code>Gtk.PositionType.RIGHT</code>, a column is inserted.</p></item>
      <item><p><code>set_row_homogeneous(True)</code> and <code>set_column_homogeneous(True)</code> ensure that (respectively) every row or every column has the same width or height.</p></item>
      <item><p><code>set_row_spacing(spacing)</code> and <code>set_column_spacing(spacing)</code> force a spacing between (respectively) rows or columns. The value of <code>spacing</code> can be between <code>0</code>, which is the default value, and <code>32767</code>.</p></item>
