MXML Namespaces
If you want to use custom components (outside of the mx or flash packages),
first you'll have to setup a namespace tell Flex where to find your custom controls.
(Using custom controls in your MXML can be a little tricky at first.)
See the end of this document for some links to external information about Namespaces.
The Default Namespace
http://www.adobe.com/2006/mxml
An MXML document created by Flex Builder will automatically bind
the mx namespace to the Flex Core Library.
Using Custom Namespaces
Example, setup a namespace referencing the package my.custom.controls:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:mycontrols="my.custom.controls.*" >
The "xmlns:mycontrols" declares an XML namespace, "mycontrols".
You can now refer to your custom components in the MXML using the namespace.
<mycontrols:CustomComponent id="abc" ... />
The declaration of your (mycontrols:CustomComponent) element has the following parts:
- mycontrols - The namespace you setup, tells Flex the package your components are in
- CustomComponent - The name of the class/component in the package
Of course you can setup several package/namespace bindings in MXML.
