Declaration [src]
void
maplibre_native_ffi_map_get_style_layer_property_async (
MaplibreNativeFfiMap* self,
const char* layer_id,
const char* property_name,
GAsyncReadyCallback callback,
gpointer user_data
)
Description [src]
Reads a property of a layer in the map’s style.
The value can differ in form from the value that was set: a color set as
"#ff0000" reads back as ["rgba", 255, 0, 0, 1].
Completes with no value when the layer doesn’t set the property.
See mln_map_get_style_layer_property in the
C API reference.
It fails with these errors:
MAPLIBRE_NATIVE_FFI_ERROR_NOT_FOUNDwhen the style has no layer namedlayer_id.
This method completes asynchronously. Use maplibre_native_ffi_map_get_style_layer_property_finish() inside the GAsyncReadyCallback to obtain the result of the operation.
