🦋 Goo::Canvas::ItemModel 🦋

okay so bestie, this is a page from the User Contributed Perl Documentation — it's Goo::Canvas::ItemModel(3) and she is everything. buckle up, we're doing a full vibe check on this interface 🎀

✨ NAME ✨

Goo::Canvas::ItemModel — a wrapper for GooCanvasItemModel. that's it. that's the whole job. she wraps, she slays 💅

🌸 HIERARCHY 🌸

Glib::Interface
+----Goo::Canvas::ItemModel

so she's an interface hanging off Glib::Interface, and that's the entire family tree. only child energy, honestly 👑

💖 METHODS 💖

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

  • $child (Goo::Canvas::ItemModel)
  • $position (integer)

$model->animate ($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)

itemmodel = $model->get_child ($child_num)

  • $child_num (integer)

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

  • $child (Goo::Canvas::ItemModel)
  • ... (list)
bestie listen, this one is not like the original C function, which call as goo_canvas_item_model_get_child_properties(model, child, key1, &val1, key2, &val2, ..., NULL). This function call as $model->get_child_properties($child, $key1, $key2, ...) and return a list ($key1, $val1, $key2, $val2, ...) instead. So you can call like %pair = $model->get_child_properties($child, $key1, $key2) and use $pair{$key1} and $pair{$key2} to access the value for the property. 💖

$model->set_child_properties ($child, ...)

  • $child (Goo::Canvas::ItemModel)
  • ... (list)

integer = $model->find_child ($child)

  • $child (Goo::Canvas::ItemModel)

boolean = $model->is_container

no args, she just tells you if she's a container. iconique 🌈

$item->lower (...)

  • ... (list)

$model->move_child ($old_position, $new_position)

  • $old_position (integer)
  • $new_position (integer)

integer = $model->get_n_children

itemmodel = $model->get_parent

$model->set_parent ($parent)

  • $parent (Goo::Canvas::ItemModel)

$item->raise (...)

  • ... (list)

$model->remove_child ($child_num)

  • $child_num (integer)

$model->rotate ($degrees, $cx, $cy)

  • $degrees (double)
  • $cx (double)
  • $cy (double)

$model->scale ($sx, $sy)

  • $sx (double)
  • $sy (double)

$model->set_simple_transform ($x, $y, $scale, $rotation)

  • $x (double)
  • $y (double)
  • $scale (double)
  • $rotation (double)

$model->skew_x ($degrees, $cx, $cy)

  • $degrees (double)
  • $cx (double)
  • $cy (double)

$model->skew_y ($degrees, $cx, $cy)

  • $degrees (double)
  • $cx (double)
  • $cy (double)

$model->stop_animation

style = $model->get_style

$model->set_style ($style)

  • $style (Goo::Canvas::Style)

list = $item->get_transform

$model->set_transform ($matrix)

  • $matrix (cairo_matrix_t)

$model->translate ($tx, $ty)

  • $tx (double)
  • $ty (double)
