Hi Randy and Pratik,
I merged the new M7 text editor sample code into my M4-derived code
today to take advantage of some bug fixes and I'm getting some weird
behaviour. All the text is appearing in the top left hand of the cell
editor. The previous code used TextLayoutParts to put all the runs one
after the other, and this class has been removed. Is there a known
issue there? Where should I start to determine why text is being placed
incorrectly?
Thanks,
Fred

Oh, boy. It's not easy following that code. I know I was confused as hell
the first time I saw it. But, if you want to, you can start by looking at
BlockFlowLayout and ParagraphTextLayout.
The figures in the text package use FlowBoxes to place their text. So, a
TextFlow will divide its text into different fragments (a different fragment
is where the text would wrap, or the text's bidi level changes). The
TextFragmentBoxes are positioned by the ParagraphTextLayout, which puts them
in the BlockBox (which is positioned by the BlockFlowLayout). When it comes
time to paint the text, the text is drawn where the fragment is positioned.
The fragments themselves are not figures and are not painted. They just
represent some text.
