</div>
<div class="refsect1" title="Initialization">
<a id="idp20913440"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>ihandle</em></span> – an integer number used a univocally-defined handle for identifying a specific HVS box (see below).
</p>
<p>
<span class="emphasis"><em>inumlinesX, inumlinesY</em></span> - number of vertical and horizontal lines delimiting the HVS squared areas
</p>
<p>
<span class="emphasis"><em>iwidth, iheight</em></span> - width and height of the HVS box
</p>
<p>
<span class="emphasis"><em>ix, iy</em></span> - the position of the HVS box
</p>
<p>
<span class="emphasis"><em>image</em></span> – (optional, default 0) an integer number denoting an RGB image opened with the <span class="emphasis"><em>bmopen</em></span> opcode. A zero indicates no image.

<h2>Performance</h2>
<p>
<span class="emphasis"><em>FLhvsBox</em></span> is a widget able to visualize current position of the HVS cursor in an HVS box (i.e. a squared area containing a grid). The number of horizontal and vertical lines of the grid can be defined with the <span class="emphasis"><em>inumlinesX, inumlinesY</em></span> arguments. This opcode has to be declared inside an <a class="link" href="FLpanel.html" title="FLpanel"><em class="citetitle">FLpanel</em></a> - <a class="link" href="FLpanelEnd.html" title="FLpanelEnd"><em class="citetitle">FLpanelEnd</em></a> block. See the entry for <a class="link" href="hvs2.html" title="hvs2"><em class="citetitle">hvs2</em></a> for an example of usage of <span class="emphasis"><em>FLhvsBox</em></span>.
</p>
<p>
<a class="link" href="FLhvsBoxSetValue.html" title="FLhvsBoxSetValue"><em class="citetitle">FLhvsBoxSetValue</em></a> is used to set the cursor position of an <span class="emphasis"><em>FLhvsBox</em></span> widget.
