I'm porting a little Morphic geometry program from Morphic to a Spec 2 application using GTK.
I need to draw a shape in an SpAthensPresenter but to draw it I need to know the current dimensions (extent) of the presenter so it can still work OK even when the window is resized. The old Morphic version also used An Athens canvas but I had no problem then as a morph has an extent method that provides this information. But now that I can't use a morph I find that the extent method of an SpPresenter always seems to answer nil. Is that right? How d you get the current size of a presenter? Is it a bug? I'm using a very recent Pharo 9 image and headless VM on Linux.
