Please check the class comments of OBInteractionRequest and subclasses. "OBInteractionRequest is an abstract superclass for notifications that request some interaction with the user. It's useful for catching such notifications in an exception handler, while allowing other notifications to operate normally." So all these requests are interacting in some way with the user, e.g. they open a new browser, they close a browser, they refresh a browser, they show a specific dialog, they change the mouse cursor, etc. And depending on the current view these requests are handled differently. In OB-Morphic the respective morphic actions are performed, in OB-Web the request is serialized to JSON and performed on the client side, ... and in the tests the events are silently captured and verified using assertions. OBCommand is something entirely different. It represents the first-class actions (menu items, buttons) in a browser. The only way an OBCommand can interact with the user and for example request additional information is through OBInteractionRequests that might be triggered at any point.

Re: [Pharo-project] Graphics with Anti-Aliasing

by Udo Schneider

WatchMorph was a good starting point. It seems that #line:to:color: does not use Antialiasing. I.e. form := Form extent: 640@480 depth: 32. form fillWhite. canvas := BalloonCanvas on: form. canvas aaLevel: 4. canvas line: 0@0 to: 640@480 color: Color red. morph := ImageMorph new. morph image: form. morph openCenteredInWorld. "morph abandon." does not show any antialiasing. Replacing it with #drawPolygon:color:borderWidth:borderColor does use AntiAliasing: form := Form extent: 640@480 depth: 32. form fillWhite. canvas := BalloonCanvas on: form. canvas aaLevel: 4. canvas drawPolygon: { 0@0 . 640@480 } color: Color transparent borderWidth: 1 borderColor: Color red. morph := ImageMorph new. morph image: form. morph openCenteredInWorld. "morph abandon." That's a "solution" I can live with - as unintuitive as it is though ... Thanks for your help.
