HIERARCHY¶
Glib::Interface
+----Goo::Canvas::Item
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.
$item->set_child_properties ($child, ...)¶
