On the "Window" tab, in the "Order" group, click "Initialization".
In the window that appears, use the arrows on the right to change the order in which the controls are initialized.

Optional Event: Modification of a marker cluster

The "Modify a marker cluster" event is executed when a Map control containing clusters is displayed. This event is executed for each marker cluster found. It is mainly used to change how the cluster is displayed.

This event has the following format:

PROCÉDURE ModifCluster(tabMarqueur est un tableau de Marqueurs)

where arrMarker is an array containing variables of type Marker associated with the cluster.
This event can return:

nothing or an empty string: in this case, the cluster's default display will be used.
image path: this image will be used to represent the cluster.
a variable of type MarkerImage, used to customize the cluster image.
