It is a subclass of <a class="link" href="class-canvas-item-model-simple.html" title="goocanvas.ItemModelSimple"><code class="classname">goocanvas.ItemModelSimple</code></a>
and so inherits all of the style properties such as "stroke-color", "fill-color" and "line-width".
It also implements the <a class="link" href="class-canvas-item-model.html" title="goocanvas.ItemModel"><code class="classname">goocanvas.ItemModel</code></a>
interface, so you can use the <a class="link" href="class-canvas-item-model.html" title="goocanvas.ItemModel"><code class="classname">goocanvas.ItemModel</code></a>
functions such as <code class="methodname"><a class="link" href="class-canvas-item-model.html#method-goocanvasitemmodel--raise-" title="goocanvas.ItemModel.raise_">goocanvas.ItemModel.raise_()</a></code>
and <code class="methodname"><a class="link" href="class-canvas-item-model.html#method-goocanvasitemmodel--rotate" title="goocanvas.ItemModel.rotate">goocanvas.ItemModel.rotate()</a></code>.
To respond to events such as mouse clicks on the ellipse you must connect to the signal handlers
of the corresponding <a class="link" href="class-canvas-grid.html" title="goocanvas.Grid"><code class="classname">goocanvas.Grid</code></a>
objects. (See <code class="methodname"><a class="link" href="class-canvas.html#method-goocanvas--get-item" title="goocanvas.Canvas.get_item">get_item</a></code> and
GooCanvas::item-created.)

Creates a new canvas grid model.

Here's an example showing how to create a grid model:
</p><pre class="programlisting">
grid = goocanvas.GridModel(parent=root,
x=100,
y=100,
width=400,
height=200,

x_offset=10,
y_offset=10,

horz_grid_line_color="yellow",
vert_grid_line_width=2.0,
vert_grid_line_color="red",
border_width=3.0,
