METHODS

item = Gnome2::Canvas::Item->new ($parent, $object_class, ...)

$parent (Gnome2::Canvas::Group)
$object_class (string)
... (list) property name => value pairs

Factory constructor for Gnome2::Canvas::Item subclasses.

$item->affine_absolute ($affine)

$affine (arrayref) affine transformation matrix

Replaces $item's transformation matrix.

$item->affine_relative ($affine)

$affine (arrayref) affine transformation matrix

Combines $affine with $item's current transformation.

(x1, y1, x2, y2) = $item->get_bounds

$canvas = $item->canvas

Fetch the Gnome2::Canvas to which $item is attached.

grabstatus = $item->grab ($event_mask, $cursor, $etime=GDK_CURRENT_TIME)

$event_mask (Gtk2::Gdk::EventMask)
$cursor (Gtk2::Gdk::Cursor)
$etime (unsigned)

$item->grab_focus

$item->hide

$affine = $item->i2c_affine

Fetch the affine transform that converts from item-relative coordinates to canvas pixel coordinates.

Note: This method was completely broken for all $Gnome2::Canvas::VERSION < 1.002.

$affine = $item->i2w_affine

Fetch the affine transform that converts from item's coordinate system to world coordinates.

Note: This method was completely broken for all $Gnome2::Canvas::VERSION < 1.002.

$item->lower ($positions)

$positions (integer)

$item->lower_to_bottom

$item->move ($dx, $dy)

$dx (double)
$dy (double)

$canvasgroup = $item->parent

Fetch $item's parent group item.

$item->raise ($positions)

$positions (integer)

$item->raise_to_top

$item->reparent ($new_group)

$new_group (Gnome2::Canvas::Group)

$item->request_update

$item->reset_bounds

Reset the bounding box of $item to an empty rectangle.

$item->show

$item->ungrab ($etime=GDK_CURRENT_TIME)

$etime (unsigned)

$item->update_bbox ($x1, $y1, $x2, $y2)

$x1 (integer)
$y1 (integer)
$x2 (integer)
$y2 (integer)

Set $item's bounding box to a new rectangle, and request a full repaint.

(x, y) = $item->w2i ($x, $y)

$x (double)
$y (double)
