[Mapserver-users] styleObj? member of classObj?

[Daniel Morissette]

Gerald,

You have to call $class->GetStyle( style_index ) to access a given
style.  And you use ms_newStlyeObj($class) to create a new style inside
a class.

<long_story>
Since there can be more than one style in a class, we cannot present a
single class member called style like we do for style->label for
instance.  We would have to present an array of styles, not just a
single style... I guess we could have tried to do it this way, but there
may have been some issues with the PHP wrappers and anyway the
getStyle() approach was more consistent with the way layers are accessed
inside the map, and the way classes are accessed inside layers.
</long_story>
