METHODS

  $item->add_child ($child, $position)

•   $child (Goo::Canvas::Item)

•   $position (integer)

  $item->allocate_area ($cr, $requested_area, $allocated_area, $x_offset, $y_offset)

•   $cr (cairo_t)

•   $requested_area (GooCanvasBounds)

•   $allocated_area (GooCanvasBounds)

•   $x_offset (double)

•   $y_offset (double)

  $item->animate ($x, $y, $scale, $degrees, $absolute, $duration, $step_time, $type)

•   $x (double)

•   $y (double)

•   $scale (double)

•   $degrees (double)

•   $absolute (boolean)

•   $duration (integer)

•   $step_time (integer)

•   $type (Goo::Canvas::AnimateType)

  GooCanvasBounds = $item->get_bounds

  canvas = $item->get_canvas

  $item->set_canvas ($canvas)

•   $canvas (Goo::Canvas)

  item = $item->get_child ($child_num)

•   $child_num (integer)

  list = $item->get_child_properties ($child, ...)

•   $child (Goo::Canvas::Item)

•   ... (list)

Not like the original C function, which call as goo_canvas_item_get_child_properties(item, child, key1, &val1, key2, &val2, ..., NULL). This function call as $item->get_child_properties($child, $key1, $key2, ...) and return a list ($key1, $val1, $key2, $val2, ...) instead. So you can call like %pair = $item->get_child_properties($child, $key1, $key2) and use $pair{$key1} and $pair{$key2} to access the value for the property.
