Area Filter symbol component

The area filter of the SA_Alarm_RuntimePage symbol lists ArchestrA areas in a hierarchical tree structure. By selecting areas from the tree, alarms can be included or excluded from the symbol. Gray shading behind an area name identifies the active area filter.

The topmost area shown in the tree is regarded as the default area, which is assigned as the reference value of the symbol's DefaultAreaName custom property.
