Function Documentation

◆ ED_area_find_region_xy_visual()

ARegion * ED_area_find_region_xy_visual	(	const ScrArea *	area,
		int	regiontype,
		const int	event_xy[2] )

Similar to BKE_area_find_region_xy() but when event_xy intersects an overlapping region, this returns the region that is visually under the cursor. E.g. when over the transparent part of the region, it returns the region underneath.

The overlapping region is determined using the ED_region_contains_xy() query.

◆ ED_region_contains_xy()

bool ED_region_contains_xy	(	const ARegion *	region,
		const int	event_xy[2] )

Note: This may return true for multiple overlapping regions. If it matters, check overlapped regions first (ARegion.overlap).
