<h2>Draw a grid grob</h2>
<h3>Description</h3>
<p>
Produces graphical output from a graphical object.
</p>
<h3>Usage</h3>
<pre>
grid.draw(x, recording=TRUE)
</pre>
<h3>Arguments</h3>
<table summary="R argblock">
<tr valign="top"><td><code>x</code></td>
<td>
An object of class <code>"grob"</code> or NULL.</td></tr>
<tr valign="top"><td><code>recording</code></td>
<td>
A logical value to indicate whether the drawing
operation should be recorded on the Grid display list.</td></tr>
</table>
<h3>Details</h3>
<p>
This is a generic function with methods for grob and gTree objects.
</p>
<p>
The grob and gTree methods automatically push any viewports in a
<code>vp</code> slot and automatically apply any <code>gpar</code> settings
in a <code>gp</code> slot. In addition, the gTree method pushes and
ups any viewports in a <code>childrenvp</code> slot and automatically
calls <code>grid.draw</code> for any grobs in a <code>children</code> slot.
</p>
<p>
The methods for grob and gTree call the generic hook functions
<code>preDrawDetails</code>, <code>drawDetails</code>, and <code>postDrawDetails</code>
to allow classes derived from grob or gTree to perform
additional viewport pushing/popping and produce additional
output beyond the default behaviour for grobs and gTrees.
</p>
<h3>Value</h3>
<p>
None.</p>
