[java-gnome-hackers] Layout size related methods

[Andrew C. <an...@op...>]

Vreixo,

I've been working on the 'pango' branch. I'd like to include it in 4.0.9
as it nicely complements the 'textview' work.

I'm a bit concerned about the size related methods in Layout. I've taken
an number of different cracks at it, and now I've got it to:

        getSizeWidth()
        getSizeHeight()

and

        getPixelWidth()
        getPixelHeight()

which seems to be a fairly decent stab at regularizing the completion
space. Still, I'm not 100% about it.

Part of my doubt is that now that we've got these normalized, these
methods now seem to return the same thing - just the sort of thing to
make me somewhat unconvinced that we actually need both pairs. That
said, it is probably best we leave both sets there - there is return
type to be considered.

The real issue, of course, is *explaining* what the difference is, and
that's where I got a bit vague. I have a hunch that it is the whole
points vs device units vs pixels thing that I'm getting confused by.

And, of course, just to spice things up, none of these have anything to
do with Layout's setWidth() but its probably best to leave that one
alone too [I am tempted by setWrapWidth()]. For now I added some extra
emphasis to its documentation in an attempt to make things clear.

My work (building on yours) is at 'hackers/andrew/pango'.
