Method

MaplibreNativeFfiMapbegin_command_group_async

Declaration [src] 

void
maplibre_native_ffi_map_begin_command_group_async (
  MaplibreNativeFfiMap* self,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description [src]

Holds back the map’s changes from rendering until maplibre_native_ffi_map_end_command_group_async(), so they show in the same frame.

Groups nest, and the changes render when the outermost group ends.

See mln_map_begin_command_group in the C API reference.

Without callback, nothing reports whether the call succeeds.

This method completes asynchronously. Use maplibre_native_ffi_map_begin_command_group_finish() inside the GAsyncReadyCallback to obtain the result of the operation.

Parameters

callback

Type: GAsyncReadyCallback

The callback to call when the call finishes.

The argument can be NULL.
user_data

Type: gpointer

The data to pass to callback.

The argument can be NULL.
The data is owned by the caller of the method.
