A Web Map Context document is just one type of model supported.
|
| 6 |
|
|
The configuration for this page demonstrates the mapbuilder
|
| 7 |
|
|
implementation for Context Collections.
|
| 8 |
|
|
This is an XML document which contains a list of context document URLs and a title.

|

<div id="collectionList"></div>
|
| 12 |
|
|
|
| 13 |
|
|
<table width="100%">
|
| 14 |
|
|
<tr>
|
| 15 |
|
|
<td id="mainButtonBar" align="left" valign="top" width="18"/>
|
| 16 |
|
|
<td id="mainMapPane"/>
|
| 17 |
|
|
</tr>
|
| 18 |
|

</table>
|

|
The widget for a context Collection is a text listing of the map titles
|
| 22 |
|
|
to be selected and is also generated by an XSL stylesheet.
|
| 23 |
|
|
Other widgets could defined to support a dynamic menu system for example.
|
| 24 |
|
|
</p>
|
| 25 |
|
|
|
| 26 |
|
|
<p>
|
| 27 |
|
|
In this case, the tools of the model are simply HTML links which execute
|
| 28 |
|
|
a JavaScript method. Note how the context model is set as the target of the
|
| 29 |
|
|
action using the <tagetModelId> property in the CollectionList widget.
|
| 30 |
|
|
The links call the JavaScript config[targetModelId].loadModel(modelUrl) method.
|
| 31 |
|
|
</p>
|
| 32 |
|
|
|
| 33 |
|
|

|
| 34 |
|
|
The MVC design pattern allows other document types to be supported very easily.

Please see the mapbuilder-lib Software Design Description
