ViewerAbort.mesa. this interface allows testing, setting, and resetting an "abort" bit for an arbitrary viewer, i.e. the viewer does not have to be typescript. If the viewer does view a typescript, the effect is the same as calling the corresponding procedure in TypeScript. Note that SetUserAbort[viewer] is performed whenever the user types control-del while editing a tioga document.
DIRECTORY
ViewerClasses USING [Viewer]
;
ViewerAbort:
CEDAR DEFINITIONS = BEGIN
UserAbort:
PROCEDURE [viewer: ViewerClasses.Viewer]
RETURNS [
BOOL];
returns TRUE if the user has aborted in this viewer.
SetUserAbort: PROCEDURE [viewer: ViewerClasses.Viewer];
ResetUserAbort: PROCEDURE [viewer: ViewerClasses.Viewer];
END.
