Indeed, zooming and scaling are things that should be significantly improved.
Milton worked on the #focusOnCenterScaled: method
Right now, we have no solution. Help is appreciated

Thanks, now I have more insight.
Now there is one concern:
| v |
v := RTView new.
v addAll: ((RTEllipse new size: 20) elementsOn: (1 to: 100)).
RTGridLayout on: v elements.
v canvas camera focusOnCenterScaled: 500.
v
That stuff is not centred :)

It works well I think. Try this:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
| v |
v := RTView new.
v canvas addMenu: 'Left' callback: [ v canvas camera translateBy: -5 @ 0. v
signalUpdate ].
v canvas addMenu: 'Right' callback: [ v canvas camera translateBy: 5 @ 0. v
signalUpdate ].
v canvas addMenu: 'Up' callback: [ v canvas camera translateBy: 0 @ -5. v
signalUpdate ].
v canvas addMenu: 'Down' callback: [ v canvas camera translateBy: 0 @ 5. v
signalUpdate ].
v addAll: ((RTEllipse new size: 20) elementsOn: (1 to: 100)).
RTGridLayout on: v elements.
v

However, when you open a view, the camera is centered at the center of all the elements
(ie. focusOnCenter). So far, this has worked pretty well, however this can be changed.
Cheers,

https://www.iam.unibe.ch/mailman/listinfo/moose-dev Yes, the thing is that I do:
view canvas camera translateBy: 1000@1000.
view signalUpdate.
and nothing happens. Do you have any more suggestions of what I can check?

P.S. Of course #translateBy works because it’s used during dragging. Can the issue be
related to use GTInspector? Is something not initialised before view is being displayed
for a first time?

https://www.iam.unibe.ch/mailman/listinfo/moose-dev You need to send #signalUpdate to the view after
having changed the camera

better API in Roassal2. There are still some things that I don’t understand. Eg. when I
send #translateTo:, #translateBy: and related things like #focusOnCenter to TRCamera,
nothing happens (at least in GTInspector view). Is there a specific way to use it? Or it’s
still work in progress?
