Layer - Vector "blank"

[adube]

Currently...

Currently, widgets that need to create blank vector layers do so independently. For examples, the shortcut widget create blank vector layers for the purpose of "highlighting" re-centered features, the redlining widget creates its own "cosmetic" vector layer, etc.

Need

We need to have a way for multiple widgets to use the same "blank" vector layer.

Solution

Modify the !Layer widget in order to be able to do so by using the "servicetype" equal to "vector" or something like that, thus creating a blank widget. By using the widget name, we can then use it after as an option value for other widgets.

Map widget

We need to be sure that this method will work with the Map widget as well.

r1017, featuring :

• new 'VectorLayer' widget. Because the 'Layer' widget needs to be binded to resources, we can't use it to create blank vector layers. For that reason, this new widget was added.
• added to the QueryOnClick 'multi' sample
• documentation
• support by both the MapPanel+Layer widgets and Map widgets.
• supported by the PGSQLMapContextConfig driver

Done.
