<h1>B</h1>
<dl>
<dt><a name="+BlobField"><code>+BlobField</code></a>
<dd>A field that handles data stored in external files, i.e. "Blob - binary
large object".
<pre><code>
(gui '(+BlobField) '(txt : home obj) 72 20)
</code></pre>
The code above creates a textarea, size 72 x 20, and stores the text entered
there in an external file. A corresponding, global variable, is created in
main.l:
<pre><code>
(setq
*Pool "db/wiki/"
*Blob "db/wiki/blob/"
*Jnl (and (info "fifo/wiki") "fifo/wiki")
*Salt (16 . "$6$@1$")
*Css '("@lib.css" "wiki/lib.css")
*WikiCss "wiki/wiki.css"
*WikiPort 5000 )
</code></pre>
Here, <code>*Blob</code> holds a path to the place where content from
<code>+BlobField</code> will be stored. See also <a
href="refR.html#+/R">+/R</a>, <a href="refT.html#+TextField">+TextField</a>.
</dl>
<dl>
<dt><a name="+Button"><code>+Button</code></a>
<dd>A basic button. A +Button takes:
<ul>
<li>A label, which may be either a string or the name of an image file.</li>
<li>An optional, alternative label. This is shown when the button is disabled.</li>
<li>An executable expression</li>
</ul>
For example:<br/>
<pre><code>
(gui '(+Button) "Enabled" "Disabled" '(doSomething))
</code></pre>
