5.4.19 NEXTG wattribute

Definition

NEXTG indicates the action that occurs if this window receives focus but no gadget within the window receives focus.

If an application attempts to assign a value to NEXTG that does not identify a gadget that has been defined for the window, an error condition occurs with $ECODE containing ",M?4," and $EREF containing a value that indicates the ssvn reference for which the error occurred.

If the NEXTG wattribute for window W identifies a gadget G that cannot get focus, that gadget's NEXTG elattribute determines where focus goes. This process is repeated for successive Gs until (a) gadget G's NEXTG elattribute identifies a previously identified gadget G or gadget G's NEXTG elattribute is not specified, in which case focus remains at window W; or (b) gadget G's NEXT elattribute identifies a gadget Gn which can get focus is reached, in which case focus goes to gadget Gn.

The effect is not specified if NEXTG identifies a gadget whose ACTIVE elattribute is FALSE or if NEXTG identifies a gadget that is obscured or if NEXTG identifies a gadget that has been destroyed after the value identifying it was assigned to NEXTG.
