I'm trying to create a row on a pane with a left justified name, some space and a right justified number.

I created the row as follows:

aRow := AlignmentMorph newRow color: aColor.
aRow
    addMorph: (TextMorph new contents: aName);
    addMorphBack: (AlignmentMorph newSpacer: Color transparent);
    addMorphBack: (TextMorph new contents: aNumber printString).

Everything displays correctly, but:

- Why is the first submorph left justified and the last one right 

justified? - Why does the first submorph allow editing and the last one doesn't? - How can I prevent editing? I want display only. I tried to use StringMorph's but after much experimentation with wrapping in AlignmentMorphs, I trimmed the example down to this.

Thanks - I'm finally trying to learn Morphic so I can teach a 14 year old... -david

Actually, I think you wanted to start with a StringMorph.

Forgive me if the following isn't the most elegant solution. I'm a Smalltalk newbie, and have no Morphic documentation, with perhaps too-deep a background using TeX-style boxes.

I think you may be thinking about this somewhat sideways about the problem. It is difficult to meaningfully define the terms "left justification" or "right justification" without first specifying a fixed width in which the text is to appear. All text in a variable length field is simultaneously left, center and right-justified. Thus, you first need to create fixed length areas in which to have your text displayed.

So, start by thinking about putting a single StringMorph into an AlighnmentMorph, setting the AlignmentMorph's extents to your desired width, the orientation to vertical, the centering to #topLeft, #center, or #bottomRight as appropriate, and you have a nice field with the specified text appropriately justified in the sepcified width.

You would make two such combinations: One for the text and one for the number. Then, you could combine them into a horizontally oriented AlignmentMorph to get the desired effect. The result looks something like this:

+---- One external Horizontal AlignmentMorph --- . . . . . . ----+ |+------------------+ +---------------------+ +----------------------+| ||topLeft string | | spacer | | bottomRight num || |+------------------+ +---------------------+ +----------------------+| +---- , , , ^ . . . ----+ | + 3 internal vertical AlignmentMorphs

This should do the trick -- messing around in a MorphWorld, while diddling the parameters in inspectors, this appeared to do just the trick.
