This is a problem I am anxious to solve. Run this program:
\starttext \newbox\testbox \hbox{% % centered \setbox\testbox=\vbox{\vskip5mm\framed[frame=on,align=disable,width=1cm,height=2cm,offset=0pt,location=depth,top=\vss,bottom=\vss]{lp}\vskip5mm} \the\ht\testbox \box\testbox % bottom \setbox\testbox=\vbox{\vskip5mm\framed[frame=on,align=disable,width=1cm,height=2cm,offset=0pt,location=depth,top=\vss,bottom=\empty]{lp}\vskip5mm} % note leaveout bottom=, not good \the\ht\testbox \box\testbox % top \setbox\testbox=\vbox{\vskip5mm\framed[frame=on,align=disable,width=1cm,height=2cm,offset=0pt,location=depth,top=\empty,bottom=\vss]{lp}\vskip5mm} % note leaveout top=, not good \the\ht\testbox \box\testbox } \stoptext
Now the middle box comes out higher than the other two, like this: � �� �� �� �� �------------ ------------� �| � �� �� �|� �------------ | � �� �� �|� �| � �� �� �|� �|lp� � �� �| | � �� �� �|� �| � �� �� �|� �| � �� �� �| | � �� �� �|� �| � �� �� �|� �| � �� �� �| |lp� � �� �|� �| � �� �� �|� �| � �� �� �| | � �� �� �|� �| � �� �� �|� �| � �� �� �| | � �� �� �|� �| � �� �� �|� �| � �� �� �| | � �� �� �|� �|lp� � �� �|� �| � �� �� �| ------------� �------------� �------------ The \ht's will tell the difference, the \dp's are 0 here. Using \vtop gives analogous results, then the depth of middle box is greater.
Probing with [depth=0pt] makes no difference. Setting [strut=yes/no] makes some difference but is not the cause of the difference. Setting [align=no/line] makes no difference. Omitting [align=..] or using [align=normal] makes all boxes the same height but puts every contents in the middle, which is not what I want: one at the top, one in the middle and one at the bottom.
How can I get the required result with all three the same height? \starttext
