SetLineStyle(filterResult, scaleZone, lineStyle)
Sets a line style of line features of the specified type and boundaries of area features of the specified type for which applying the filter results in filterResult. The result of applying the filter is defined by constants given in the "Results of Applying Filter Conditions" table. The scaleZone argument specifies the scale zone in the theme for which a line style is set. If the scaleZone argument is not Null, then the filterResult argument is ignored. The lineStyle argument is the LineStyle object. If the lineStyle argument equals Null, the line style is cancelled. If the Layer object (the feature type owner) belongs to the Theme::Layers collection, a line style influences only the style of displaying features of the specified type of the theme (the layer owner). If the Layer object (the feature type owner) does not belong to the Theme::Layers collection, the gdbFilterResultIndifferent constant can be used as the filterResult argument and the scaleZone argument must be Null. This method can be applied to feature types of spatial category either line or area (the FeatureType::SpatialCategory property returns either gdbSpatialCategoryLine or gdbSpatialCategoryArea constant). If the feature type belongs to a work layer, only the gdbFilterResultIndifferent constant can be used as the filterResult argument.
