Horizontal alignment of texts in different nodes

I am attempting to draw a tree using the commands from the Trees  
library, but one small matter has defeated me. I have nodes  
containing 2-3 lines of text, and these nodes are horizontally  
aligned with each other. I would like, say,  the two lines of text in  
horizontally adjacent nodes also to be horizontally aligned, but this  
does not always happen. If the top line of one node contains a letter  
with an ascender (e.g. b, d, f) and the top line of the adjacent  
node  contains only letters without ascenders (e.g. c, e, g, s), then  
the top-line baselines are not aligned from node to node because the  
presence of the ascender in one changes its line height. Spacing  
between the lines of the label also seems to be altered by ascenders  
and descenders.

I have the feeling that \pgftext ought to offer a solution to this  
problem, but I am unable to make it work inside a tree node.

Any solutions would be very gratefully received.

Re: Horizontal alignment of texts in different nodes

Hello everyone,

in the CVS there is now a new option called "growth parent anchor"  
that was introduced exactly for such problems. Also, the current CVS  
contains lots of new stuff having to do with matrix alignments that  
can also help in this context.

For the time being, try adding a \strut at the beginning of nodes,  
although that is not really "the right solution".

Best regards,
Till

Re: Horizontal alignment of texts in different nodes

My thanks to Mark and Till for their advice. A custom-made variant of  
\strut does indeed achieve what I wanted. And I look forward to the  
day when the CVS version becomes the next published version, as I  
have made extensive use of matrix alignments in linguistics diagrams  
made with other graphics applications.

All the best,

Malcolm
