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)
