Control.focus Event

Raised when the Control is focused.

Namespace: MindFusion.Mapping
Package: Control.js

 Syntax

JavaScript

EventDispatcher focus

 Event Data

The event handler method receives the following arguments:
sender
A Control instance, which is the source of the event. This object will be passed to the handler function as the first argument.
args
An EmptyEventArgs instance, which contains event data. This object will be passed to the handler function as the second argument.

 Example

The following example creates a new MapView using a <DIV> element called "mapview" that we've declared in the HTML code of the page. Then it handles the focus event. The MapView class derives from Control.

JavaScript

var m = MindFusion.Mapping;// create a new instance of the mapView
var view = new m.MapView(document.getElementById("mapView"));
view.theme = "light";
...................
.....................
view.focus.addEventListener( handleFocus );function handleocus( sender, args )
{
    if (sender == view)
    {
       //do something
    }
}
