Gnome2::Canvas::Item(3User Contributed Perl DocumentaGnome2::Canvas::Item(3pm)

NAME
       Gnome2::Canvas::Item - Base class for all canvas items

HIERARCHY
	 Glib::Object
	 +----Glib::InitiallyUnowned
	      +----Gtk2::Object
		   +----Gnome2::Canvas::Item

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.

   (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->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)
