Yes, endless loop with step as far as I remember
stepAt: millisecondClockValue in: aWindow
| newText |
(CodeHolder smartUpdating and: [(millisecondClockValue - self
timeOfLastListUpdate) > 8000]) "Not more often than once every 8 seconds"
ifTrue:
[self updateListsAndCodeIn: aWindow.
timeOfLastListUpdate := millisecondClockValue].
newText := self contentsIsString
ifTrue: [self selection]
ifFalse: ["keep it short to reduce time to compute it"
self selectionPrintString ].
newText = contents ifFalse:
[contents := newText.
self changed: #contents]
stepTimeIn: aSystemWindow
^ (selectionUpdateTime ifNil: [0]) * 10 max: 1000
Tadaaa :)
The old Browser was doing the same, and a lot of Morphs are doing this :s
