<h2>Get a Grid Graphical Object</h2>
<h3>Description</h3>
<p>
Retrieve a grob or a descendant of a grob.
</p>
<h3>Usage</h3>
<pre>
grid.get(gPath, strict = FALSE, grep = FALSE, global = FALSE,
allDevices = FALSE)
getGrob(gTree, gPath, strict = FALSE, grep = FALSE, global = FALSE)
</pre>
<h3>Arguments</h3>
<table summary="R argblock">
<tr valign="top"><td><code>gTree</code></td>
<td>
A gTree object.</td></tr>
<tr valign="top"><td><code>gPath</code></td>
<td>
A gPath object. For <code>grid.get</code> this
specifyies a grob on the display list. For <code>getGrob</code> this
specifies a descendant of the specified gTree. </td></tr>
<tr valign="top"><td><code>strict</code></td>
<td>
A boolean indicating whether the gPath must be
matched exactly. </td></tr>
<tr valign="top"><td><code>grep</code></td>
<td>
A boolean indicating whether the <code>gPath</code> should
be treated as a regular expression. Values are recycled across
elements of the <code>gPath</code> (e.g., <code>c(TRUE, FALSE)</code> means
that every odd element of the <code>gPath</code> will be treated as
a regular expression).
</td></tr>
<tr valign="top"><td><code>global</code></td>
<td>
A boolean indicating whether the function should affect
just the first match of the <code>gPath</code>, or whether all matches
should be affected.
</td></tr>
<tr valign="top"><td><code>allDevices</code></td>
<td>
A boolean indicating whether all open devices
should
be searched for matches, or just the current device.
