Re: [Adobe-source-devel] asl-users: Problems with place and outsets

[Foster B. <fbr...@ad...>]

The problem is that I'm in a widget implementation that needs the widget to
own the entire rect pertaining to its widget's pixels on the screen-
including the outsets- otherwise those regions outside the widget's rect
won't be drawn properly. For example when I have a button that is 80x20, I
need the widget to be 88x28 to account for the 4-pixel-per-size focus ring.
This means I need to take into account the total extents of the widget, but
only for measurement; at layout time I need to inset the actual widget to
account for outsets, which is throwing off my baselines.

Blessings,
Foster
