Description

The function interface-displayed-p returns t from the time interface started to be displayed, that is the call to display, to the time that interface is fully destroyed. This means that, when interface-displayed-p returns nil, interface is a passive object in memory, and when it returns t, interface is accessed by CAPI and might be interacting with the user on the screen.

The function interface-fully-created-p returns t when interface is fully created, that is from the time it is ready to appear on the screen, through the time that it is on the screen, until it is destroyed. interface is already fully created when its create-callback, if any, is called, and when interface-display is called (which happens after the create-callback).

The functon interface-being-created-p returns t from the time interface started to be displayed until it is fully created.

The function interface-fully-destroyed-p return t when interface is fully destroyed.
