INT32 MgLayer::GetThemeCategoryCount

(

INT32

geomType

)

Gets the number of theme categories for this layer at the map's current scale for the given geometry type style. A count greater than 1 indicates a themed layer. Returns -1 if there are no applicable styles at the current scale.

.NET Syntax

virtual int GetThemeCategoryCount(int geomType);

Java Syntax

virtual int GetThemeCategoryCount(int geomType);

PHP Syntax

virtual int GetThemeCategoryCount(int geomType);

Parameters:

geomType

(int) The geometry type

Remarks:

The map's current scale is used to determine what scale range in the layer definition to search for. When geomType = 4, it will only count the number of the theme categories for the first composite style it finds. For a scale range with multiple composite type styles, you should use GetCompositeThemeCategoryCount() instead

Returns:

The number of theme categories for this layer at the map's current scale for the given geometry type style. A count greater than 1 indicates a themed layer. Returns -1 if there are no applicable styles at the current scale
