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.
