- Welcome to GooCanvas
- ====================
-
- (a cairo-based canvas widget for GTK+)
-
- GooCanvas Home Page : http://live.gnome.org/GooCanvas
-
-
- GooCanvas is similar in many ways to GnomeCanvas and FooCanvas.
- But it uses cairo for rendering, has an optional model/view split,
- and uses interfaces for items & models (so you can easily turn any
- application object into a canvas item or model).
-
- NOTE: I am no longer actively developing GooCanvas, so no major new
- features will be added (unless a new maintainer takes over). I'll still
- try to fix any bugs that appear though, and may accept minor patches.
-
- To build it run './configure' and 'make'. To run the demo cd into 'demo' and
- run './demo'. (Or run ./simple-demo for the very simple demo, or ./mv-demo
- for the model-view demo.)
-
- Features:
-
- o Optional model/view split.
- o Uses interfaces for items & views.
- o Basic items - rect/ellipse/polyline/text/image/grid/group.
- o Path item, using SVG path specification strings.
- o Table item for layout of other items (similar to the GtkTable widget).
- (This also supports items whose requested height changes according to
- their allocated width, such as text items.)
- o Embedded GTK+ widgets.
- o Layers/stacking order with raise/lower functions.
- o Cascading styles - line width/style/dashes, colors, fill patterns.
- o Affine transformations for all items - rotations/scales/skews.
- o Clip paths to support clipping items.
- o Event handling - button/motion events, "pointer-events" property like SVG.
- o Grabs - support for pointer & keyboard grabs.
- o Keyboard focus traversal.
- o Accessibility (item title & description properties and hierarchy stuff).
- o Printing (output to a given cairo_t).
- o Scrolling.
- o Zooming.
- o Static items that don't move as the canvas is scrolled or zoomed.
- o Tooltips.
- o Item visibility setting - on/off/above zoom threshold.
- o Simple animation.
- o Scalable - support for thousands of items over a large canvas area.
- o Support for different units - pixels/points/inches/millimeters.
- o API docs.

- (FooCanvas can be found in GNOME svn in the 'foocanvas' module.
- FooCanvas was based on GnomeCanvas, which is in the 'libgnomecanvas' module.)
