HSLayers.InfoPanel
==================
`HSLayers.InfoPanel <http://www.bnhelp.cz/wwwlibs/hslayers/3.0/doc/symbols/HSLayers.InfoPanel.html>`_
is again `Ext.Panel <http://www.extjs.com/deploy/dev/docs/?class=Ext.Panel>`_ which is used for displaying any relevant textual information to the user. I is used among others by query tool, but also information about line length and area, measured by specified controls, are displayed too.

Let's have a look at the example http://dev.bnhelp.cz/wwwlibs/hslayers/branches/editace/examples/InfoPanel.html

First we have to include yet another javascript

.. literalinclude:: ../../../../branches/hslayers-3.0/examples/InfoPanel.html
    :language: html
    :linenos:
    :lines: 14

Then we will create some map, with one Marker within the
OpenLayers.Layer.Marker, and will bound some functionality to the `Clear`
button of the InfoPanel (or better: we will add listener to `clearPanel`
event)


.. literalinclude:: ../../../../branches/hslayers-3.0/examples/InfoPanel.html
    :language: javascript
    :linenos:
    :lines: 16-56
