METHODS
item = Gnome2::Canvas::Item->new ($parent, $object_class, ...)
o $parent (Gnome2::Canvas::Group)
o $object_class (string)
o ... (list) property name => value pairs
Factory constructor for Gnome2::Canvas::Item subclasses.
$item->affine_absolute ($affine)
o $affine (arrayref) affine transformation matrix
Replaces $item's transformation matrix.
$item->affine_relative ($affine)
o $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)
o $event_mask (Gtk2::Gdk::EventMask)
o $cursor (Gtk2::Gdk::Cursor)
o $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.
(x, y) = $item->i2w ($x, $y)
o $x (double)
o $y (double)
$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)
o $positions (integer)
$item->lower_to_bottom
$item->move ($dx, $dy)
o $dx (double)
o $dy (double)
$canvasgroup = $item->parent
Fetch $item's parent group item.
$item->raise ($positions)
o $positions (integer)
$item->raise_to_top
$item->reparent ($new_group)
o $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)
o $etime (unsigned)
$item->update_bbox ($x1, $y1, $x2, $y2)
o $x1 (integer)
o $y1 (integer)
o $x2 (integer)
o $y2 (integer)
Set $item's bounding box to a new rectangle, and request a full repaint.
(x, y) = $item->w2i ($x, $y)
o $x (double)
o $y (double)
