[Pharo-project] simulating morphic events

Hi, I would like to simulate Morphic events, like mouseUp, but I cannot figure out the complete setup. Here is the code I have so far: | mouseUp morph | morph := self scroller submorphs first. mouseUp := MouseButtonEvent basicNew setType: #mouseUp position: (morph bounds origin + (1@1)) which: 4 buttons: 7 hand: (HandMorph new mouseFocus: morph; yourself) stamp: Time millisecondClockValue. morph handleMouseUp: mouseUp. At this moment it looks like the problem is that the eventHandler in the morph is nil. Can anyone point me into the right direction? Cheers, Doru -- www.tudorgirba.com "Yesterday is a fact.
