[Pharo-project] OBPane coordinates

by Sean P. DeNigris

Am I hallucinating, or do the OB morph classes use local coordinates e.g. #center reports the distance from the topLeft, which reports 0@0? If this is really happening right now, why is this, and how do I get their global coordinates? Thanks.

I've also augmented the hierarchy with TextLiteralHTML. In Squeak there are also TextPlusJumpStart & TextPlusJumpEnd. This hierarchy is really useful and easily extensible. It provides quite a rich facility. I write my blog posts in a workspace, using binary storage to save it, and then export it in a format that wordpress consumes (HTML with implicit line breaks at new lines, i.e. <BR>'s replaced by new lines).

Is there are update number associated with the change? The 1.4 image I used reports 14225 as the most recent update.
