I think the bug is in TRMorph.

in TRMorph, on layoutChanged, if we have a new extent (i.e. window resize), we have to create a new surface via createSurface. But createSurface will not create a surface if the current surface is not nil.

I tried by adding a forceCreateSurface and it solves my display problems and the roassal examples resizing problem.

Now, I don't feel confortable throwing away the previous surface object without a reset of some kind, but since a TRMorph doesn't bother to reset the surface when closing, this means I shouldn't bother too :)

TRCanvas>>openInWindowSized: anExtentAsPoint
| window |
self extent: anExtentAsPoint.
self buildMorph.
window := morph openInWindow.
window extent: anExtentAsPoint.
^ window

should resolve the issue. But it has to be done neatly :).

       Are you sure this is related to glamour? The problem I fixed

           Hi!

           I did something wrong in TRMorph when worked on the
           checkSession.
           The last version of Trachel should fix this problem

           Hi,

           When using Roassal 2 in a glamour browser, the
           visualization gets clipped when too large. This appears
           to occur because the canvas does not adapt to the
           container morph (a TRMorph) dimensions and retains its
           default extent.

           To reproduce:
           |browser|
           browser := GLMTabulator new.
           browser title: 'Roassal 2 Visualization'.
           browser row: #visu.
           browser transmit to: #visu; andShow: [:a |
           a roassal2
           title: 'Overview';
           painting: [ :mondView :entity | view := mondView view.
           view addAll: ((RTEllipse new color: Color purple; size:
           10) elementsOn: Collection withAllSubclasses) @ RTDraggable.
           RTEdge buildEdgesFromObjects: Collection
           withAllSubclasses from: #superclass to: #yourself inView:
           view.
           RTClusterLayout on: view elements edges: view edges.
           view edges do: [ :e | e trachelShape pushBack ].
           "view canvas extent: (950 @ 550)."
           ]].
           browser openOn: 1.

           Did someone notice similar behavior with spec? What would
           be good is that TRMorph should update the contained
           canvas extent when it is resized.
