<h2>Focusing Items and Groups</h2>
<p>Elements of Better ListView controls can be focused independently on
control focus state. Items, sub-items and groups can be focused using
mouse or keyboard.</p>
<p>When item or group is clicked, it gets focus within the Better
ListView Control. The focused item is usually displayed slightly darker
than other items (Aero theme) when selected.</p>
<p>The focused item can be recognized by <strong><em>focus
rectangle</em></strong>, which is apparent when item is focused, but not
selected:</p>
<p class="images"><img src="focus-item.png"><img src="focus-group.png"></p>
<p>When graphic theme is turned off, focus rectangle is displayed after
item or group is focused by keyboard for the first time. To hide focus
rectangle again, call <span class="code">ResetFocusRectangleDisplay</span>
method.</p>
<h2>Focusing Sub-Items</h2>
<p>Sub-items can be focused in <strong><em>Details</em></strong> view with
columns.</p>
<p>Sub-items cannot be focused by mouse, but when an item is focused,
using <span class="code">Left</span> and <span class="code">Right</span> arrow keys allows you to
move focus rectangle to subsequent sub-items:</p>
<p class="images"><img src="sub-items.png"></p>
<p>Having a sub-item focused allows you to invoke label editing of
sub-items using keyboard (see <strong><em><a href="chapter-label-edit.html">Label Editing</a></em></strong> for more
information).</p>
<h2>Detecting Focused Element</h2>
<p>Better ListView provides several properties to check which element
is currently focused:</p>
<ul>
<li>
<p><span class="code">FocusedGroup</span></p>
</li>
<li>
<p><span class="code">FocusedItem</span></p>
</li>
<li>
<p><span class="code">FocusedSubItem</span></p>
</li>
</ul>
<br><hr>
<p class="note">When a sub-item is focused (<span class="code">FocusedSubItem</span> property
is not <span class="code">null</span>), the item is focused as well.</p>
<hr>
<br><p>To detect when focused element has been change, use the
<span class="code">FocusedItemChanged</span> event. Event data contains information
about both previous and recent focused element.</p>
