Function Documentation

◆ ED_drivers_editor_init()

void ED_drivers_editor_init	(	bContext *	C,
		ScrArea *	area )

Set up UI configuration for Drivers Editor (drivers editor window) and RNA (mode switching).

Note: Currently called from window-manager.

◆ get_active_fcurve_channel()

bAnimListElem * get_active_fcurve_channel ( bAnimContext * ac )

Find 'active' F-Curve. It must be editable, since that's the purpose of these buttons (subject to change). We return the 'wrapper' since it contains valuable context info (about hierarchy), which will need to be freed when the caller is done with it.

Note: curve-visible flag isn't included, otherwise selecting a curve via list to edit is too cumbersome.
