Hello, I am having an issue where I need to refresh an object that is a subclass of RectangleMorph in a window. My object needs to travel across the screen at certain intervals. A controller object tells this RectangleMorph object where wants it, and in turn the Rectangle object sets its new position with self position: newX@ newY. but the object does not show up. It does however take the exact time it should to travel, but it just doesn't display itself. When I run the same program in debug, everything works fine, meaning I can see the object travel across the screen. Am I missing a method to refresh the object in real time? I have tried self changed, etc. Thanks Barakat -- View this message in context: http://forum.world.st/Morph-does-not-refresh-or-show-tp3700516p3700516.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
