[Moose-dev] Re: Roassal2: Camera scale callback?

Hi Jan! This is an excellent point you are making! Such a mechanism will enable an additional kind of interaction (e.g., semantic zooming). This was on my todo list of long. Your email pushed this todo at the top of my todo stack. I have updated Roassal with such a callback. Here is an example: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= TRCameraTest>>testScale | callback t | callback := TRCameraScaleCallback new. t := 0. callback block: [ :newScale | t := t + 1 ]. camera addCallback: callback. self assert: t equals: 0. camera scale: 0.5. self assert: t equals: 1. camera scale: 10. self assert: t equals: 2. camera scale: 11. self assert: t equals: 3. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Things to keep in mind: - you need to register the callback in the camera - if your callback changes something on the view, you may need to use #signalUpdate (although I haven’t tried).
