[Cartoweb-users] new tool to the Toolbar

[Pierre GIRAUD]

Hello,

I think I know the functionnalities you are about to add to the routing 
plugin. We developped some similar tools for one of our customers.

The first thing you need to know is that there is a generic way to add 
tools to the toolbar. You cannot get what you want with simply adding 
code in the templates.

This generic way uses the ToolProvider interface.
So, your php class that extends ClientRouting needs to implement the 
ToolProvider interface.
Then, you'll have to define 4 methods (handleMainmapTool, 
handleKeymapTool, handleApplicationTool, and getTools). The last one 
will probably look something like :

    const TOOL_ROUTING_FROM = 'routing_from';
    const TOOL_ROUTING_TO = 'routing_to';
   
    /**
     * Returns the routing tools : RoutingFrom, RoutingTo
     * @see ToolProvider::getTools()
     * @return array of ToolDescription
     */
    public function getTools() {
        $toolsArray = array();

        $toolsArray[] = new ToolDescription(self::TOOL_ROUTING_FROM, 
true, 101);
        $toolsArray[] = new ToolDescription(self::TOOL_ROUTING_TO, true, 
102);

        return $toolsArray;
    }

That done, you should be able to see the new tools in the toolbar. To 
get images within those tools, you need "routing_from.gif" and 
"routing_to.gif" files in the correct directory 
(plugins/routing/htdocs/gfx/).

The next step is to write the javascript methods for the tools. Edit a 
new javascript file "plugins/routing/htdocs/js/dhtmlRouting.js" (loaded 
in your templates) with the needed functions.

Map.prototype.routing_from = function(aDisplay) {
...
}

Hope this helps.
Don't hesitate to ask if this isn't clear or if you are not able to go 
further.

Regards

Pierre
