Reference Viewer Interactivity

This page is about user-driven interactivity between the Viewer and the third-party map.

When the user executes the “Zoom to Extent” action on a resource, all Views zoom to the extent of a single Resource. The reference viewer should do the same.

In order to implement this, you can listen to the onZoomToExtent Signal. When the event is dispatched, it will have a payload of type Extent. You can use this extent to perform the same zoom in the reference viewer.

When the user executes the “Move View” or “New View” functions, the user can use any View to select a position to respectively move to or open a new View at. The user should also be able to use the reference viewer to select a position.

In order to implement this, 2 Signals are available :

• onPickPositionRequested : Dispatched when a position is needed. If your user uses the reference viewer to select one, use the setPickPosition() to pass it along.
• onPickPositionCancelled : Dispatched when a position is no longer needed. The user may have used one of the other Views to pick a position.
