◆ BKE_brush_duplicate()

Brush * BKE_brush_duplicate	(	Main *	bmain,
		Brush *	brush,
		eDupli_ID_Flags	dupflag,
		uint	duplicate_options )

Perform deep-copy of a Brush and its 'children' data-blocks.

Parameters

dupflag	Controls which sub-data are also duplicated (see eDupli_ID_Flags in DNA_userdef_types.h).
duplicate_options	Additional context information about current duplicate call (e.g. if it's part of a higher-level duplication or not, etc.). (see eLibIDDuplicateFlags in BKE_lib_id.hh).

Warning: By default, this functions will clear all bmain #ID.idnew pointers (BKE_main_id_newptr_and_tag_clear), and take care of post-duplication updates like remapping to new IDs (BKE_libblock_relink_to_newid). If LIB_ID_DUPLICATE_IS_SUBPROCESS duplicate option is passed on (typically when duplication is called recursively from another parent duplication operation), the caller is responsible to handle all of these operations.

Note: Caller MUST handle updates of the depsgraph (#DAG_relations_tag_update).

◆ BKE_brush_tag_unsaved_changes()

void BKE_brush_tag_unsaved_changes ( Brush * brush )

Tag a linked brush as having changed settings so an indicator can be displayed to the user, showing that the brush settings differ from the state of the imported brush asset. Call every time a user visible change to the brush is done.

Since this is meant to indicate brushes that are known to differ from the linked source file, tagging is only performed for linked brushes. File local brushes are normal data-blocks that get saved with the file, and don't need special attention by the user.

For convenience, null may be passed for brush.
