<h2>Description</h2>
<p>
<span class="emphasis"><em>FLtabs</em></span> is a <span class="quote">“<span class="quote">file card tabs</span>”</span> interface that is useful to display several areas containing widgets in the same windows, alternatively. It must be used together with <a class="link" href="FLgroup.html" title="FLgroup"><em class="citetitle">FLgroup</em></a>, another container that groups child widgets.

<div class="refsect1" title="Syntax">

<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>FLtabs</strong></span> iwidth, iheight, ix, iy</pre>
</div>
<div class="refsect1" title="Initialization">
<a id="idp22865232"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>iwidth</em></span> -- width of widget.
</p>
<p>
<span class="emphasis"><em>iheight</em></span> -- height of widget.
</p>
<p>
<span class="emphasis"><em>ix</em></span> -- horizontal position of upper left corner of the valuator, relative
to the upper left corner of corresponding window. Expressed in pixels.
</p>
<p>
<span class="emphasis"><em>iy</em></span> -- vertical position of upper left corner of the valuator, relative to the upper left corner of corresponding window. Expressed in pixels.
</p>
</div>
<div class="refsect1" title="Performance">
<a id="idp22867576"></a>
<h2>Performance</h2>
<p>
Containers are useful to format the graphic appearance of the widgets. The most important container is <a class="link" href="FLpanel.html" title="FLpanel"><em class="citetitle">FLpanel</em></a>, that actually creates a window. It can be filled with other containers and/or valuators or other kinds of widgets.
</p>
<p>
There are no k-rate arguments in containers.
</p>
<p>
<span class="emphasis"><em>FLtabs</em></span> is a <span class="quote">“<span class="quote">file card tabs</span>”</span> interface that is useful to display several alternate areas containing widgets in the same window.
