Member Enumeration Documentation

activityState

enum VuoRendererItem::activityState

Special composition component activity states.

Definition at line 21 of file VuoRendererItem.hh.

zValues

enum VuoRendererItem::zValues

Stacking order for canvas elements.

Enumerator
portZValue	So the slight antialiasing overlap isn't visible.
attachmentZValue	Render attachments behind the port they're connected to, so the port hover highlight is consistently visible.
