<h1 id="BiGridHeaders">BiGridHeaders</h1>
<p>
This class represents the headers for a <code><a href="BiGrid.html">grid</a></code>
or a <code><a href="BiTree.html">tree</a></code>.
The headers contain several <code><a href="BiGridHeader.html">header cells</a></code>.
</p>
<p>This class extends
<code><a href="BiComponent.html">BiComponent</a></code>
and therefore all methods and fields available for
<code><a href="BiComponent.html">BiComponent</a></code>
are also available for <code>BiGridHeaders</code>.</p>

<h2>Constructor</h2>
<p><code>
new BiGridHeaders()</code></p>
<h3>Parameters</h3>
<p>No parameters.</p>
<h2>Properties</h2>
<table>
<thead>
<tr>
<td>Name</td>
<td>Type</td>
<td class="get-header">get</td>
<td class="set-header">set</td>

<td class="set-column"><img src="check.png" alt="checked"></td>
<td>
If this is <code>true</code> then the sorting should be done
ascending, if <code>false</code> descending and if <code>null</code>
no sort. This is also reflected on the <code><a href="BiGridHeader.html#ascending">ascending</a></code> property for the
<code><a href="BiGridHeader.html">header</a></code> this applies to.

<td class="get-column"><img src="check.png" alt="checked"></td>

<td class="get-column"><img src="check.png" alt="checked"></td>
<td class="set-column"><img src="check.png" alt="checked"></td>
<td>
The order in which the cell headers should be displayed in. A
value of <code>[2,0,1]</code> means that the third cell comes first,
then comes the first cell and last the second.

<td class="set-column"></td>
<td>
Returns the header acting as the filler. This is the part that is
shown after the last column if the grid is wider than all the columns
combined.

<h2>Methods</h2>
<p>None.</p>
<h2>Events</h2>
<table>
<thead>
<tr>
<td>Name</td>
<td>Type</td>
<td class="bubbles-header">Bubbles</td>
<td>Descripton</td>
</tr>
</thead>
<tbody>
<tr>
<td><a name="ascendingchanged"></a><code>ascendingchanged</code></td>
<td><code class="type"><code><a href="#BiEvent">BiEvent</a></code></code></td>
<td class="bubbles-column"></td>
<td>
Fired when the ascending property changes. This happens when either
the user clicks on a column header cell that is already sorted or
this property is changed through script.<br>
<br>
Note that if the <code><a href="#ascending">ascending</a></code> property changed due to
a change of the <code><a href="#sortColumn">sortColumn</a></code> this event is not fired.
This is by design to prevent preformance issues.
</td>
</tr>
<tr>
<td><a name="columnorderschanged"></a><code>columnorderschanged</code></td>
<td><code class="type"><code><a href="#BiEvent">BiEvent</a></code></code></td>
<td class="bubbles-column"></td>
<td>
Fired when the column orders are changed. This happens when either
the user has reordered the columns or the order is
changed through script.
</td>
</tr>
<tr>
<td><a name="columnwidthschanged"></a><code>columnwidthschanged</code></td>
<td><code class="type"><code><a href="#BiEvent">BiEvent</a></code></code></td>
<td class="bubbles-column"></td>
<td>
Fired when the column widths are changed. This happens when either
the user has finished resized a column or the column widths are
changed through script.
</td>
</tr>
<tr>
<td><a name="columnwidthschanging"></a><code>columnwidthschanging</code></td>
<td><code class="type"><code><a href="#BiEvent">BiEvent</a></code></code></td>
<td class="bubbles-column"></td>
<td>
Fired when the column widths are changing. This happens when
the user is resizing a column.
</td>
</tr>
<tr>
<td><a name="sortcolumnchanged"></a><code>sortcolumnchanged</code></td>
<td><code class="type"><code><a href="#BiEvent">BiEvent</a></code></code></td>
<td class="bubbles-column"></td>
<td>
Fired when the sort column is changed. This happens when either
the user has clicks on a sortable column or the sort column is
changed through script.<br>
<br>
Note that when the user clicks on the currently sorted column this
event is not fired. Instead the <code><a href="#ascendingchanged">ascendingchanged</a></code> event
is triggered because the sorting is changed from ascending to
descending or the other way around.
