How to use LinkQuery widget

[Julien-Samuel Lacroix <jlacroix (at) dmsolutions.ca>]

Hi,
Here's an example. In short the LinkQuery widget will open a custom 
popup if you click on the map and your query return a result:

<cwc2 type="LinkQuery" DEFAULT="TRUE" PopupWidth="770" PopupHeight="600" 
SCROLLBARS="FALSE" TOOLBAR="FALSE" MENUBAR="FALSE" STATUS="FALSE" 
RESIZABLE="FALSE"  image="icons/icon_query.png" 
ResultScript="popup.php?id=%id_attribute%&param2=%param2%" 
LinkQueryLayer="LayerName" styleresource="NavButtons" imagewidth="24" 
imageheight="24" toolset="Navigation" imagetip="Clic here">
    <image state="normal"/>
    <image state="hover"/>
    <image state="selected"/>
</cwc2>

In the example above, popup.php will be a custom php script of your own. 
Also replace the "?id=%id_attribute%&param2=%param2%" by what you want 
to pass to the php script. All %param% strings will be replaced by the 
corresponding attributes from your layer. You can see all the attributes 
of ou layer with ogrinfo.
