GetSetPosition()

Summary

Gets the position of a selection set on the current map layer.

 

Syntax

pos = GetSetPosition(string set_name)

 

Argument	Contents
set_name	The name of the selection set

 

Returns

An integer indicating the position of the set within the layer.

 

Notes

• The set position affects the way features are drawn if they belong to more than one selection set in a layer.

• When a feature is in more than one set, the settings from the first set are applied to the feature, followed by the settings for the second set, and so on. As a result, settings for a later set may override those for an earlier set.

• The highest possible set position guarantees that the settings for that set will be visible for any feature in the set.

• The layer itself is in the first set position, so the last set position is one more than the number of selection sets.

• The same selection sets in different maps can be in different positions.

Example

// Make sure that Super High income settings are always shown

setnames = GetSets()

pos = GetSetPosition("High Income")

if pos < setnames.length+1 then SetSetPosition("High Income", setnames.length+1)
