Gnome2::Canvas::Item

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.

$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)

$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)

• $x (double)
• $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)

• $positions (integer)

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

• $dx (double)
• $dy (double)

$canvasgroup = $item->parent

Fetch $item's parent group item.

$item->raise ($positions)

• $positions (integer)

$item->reparent ($new_group)

• $new_group (Gnome2::Canvas::Group)

$item->reset_bounds

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

$item->ungrab ($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)
