Vertical alignment of framed text

Vertical alignment of framed text

[Vyatcheslav Yatskovsky]

Hello,

I want to insert "hotkeys", surrounded by a round frame, into a paragraph text. I almost have achieve it, except of proper vertical alignment.

Now it is the frame that is aligned with the text bottom line. But, I want the text inside a frame to be aligned with the rest of line. 

(I found that \vcenter solves the problem but I don't know how to merge it with \defineframed. Or, maybe there is better solution?)


\defineframed
   [hotkey][height=\lineheight,offset=4pt,corner=00]

\starttext
Another way to start or stop the device is to use hotkey. If the application is active (that is, sits on the foreground of your desktop),  the hotkey is {\hotkey{Space}}. If it is not active, then use global hotkey -- \hotkey{Alt}+\hotkey{Space}.
\stoptext

Hi,

\defineframed
   [hotkey][offset=4pt,corner=00,location=low]

Hello,

Thank you Wolfgang, but 

\defineframed
   [hotkey][offset=4pt,corner=00,location=low]

produces too big frames, while

\defineframed
   [hotkey][height=\lineheight,offset=4pt,corner=00,location=low]

produces nice tight frames but places the text very BELOW the line text. (Previously the text was too much ABOVE).

If I remove offset then it looks good (on center), except I really want more right/left spacing (from the inner text to the frame) but less spacing top/below, so that It resembles a keyboard key. 

How to get just center position while keeping the frame tight and more X-stretched?

Perhaps \inframed could solve your problem? It takes case for proper
baseline placement.

There is no \defineinframed equivalent (perhaps there should be
some?), but you can still define it in the old TeX-ish way:
    \def\hotkey#1{\inframed[corner=00]{\ #1\ }}

Offset is a bit tricky: \framed only supports a single set of offset
parameters (you cannot set left/right/top/bottom offset separately).
Wolfgang (Schuster) has written a patch for leftoffset/rightoffset,
but if it's not (until it's not) part of the core, you can still add
fake space before or after the text if you're using framed with a
\def-ined command.

\inframed[height=\lineheight] doesn't work properly. (It might be a
bug, an oversight or simply something that you're not supposed to use
anyway ;)

the best way is to define your own macro, as \framed alone can't handle
this special case. if you insert an \offset macro inside \framed (with
offset=overlay to avoid additional offsets), you can use different
offset values for all directions.

you still have to lower the result, so you also need

\dontleavehmode\lower??ex\hbox{<Hotkey>}

in your final macro.

something like (untested!)

\def\Hotkey#1%
  {\dontleavehmode\lower??ex\hbox
   {\framed[offset=overlay,corner=00,...]
    {\offset[leftoffset=??em, rightoffset=??em,
       topoffset=??ex, bottomoffset=??ex]
     {#1\strut}}}}

try to use em for horizontal offsets and ex for vertical ones (instead
of fixed values). also metapost generated backgrounds (overlay) look
much better here.

happy fiddling with all the ?? ;)

Re: Vertical alignment of framed text

[Vyatcheslav Yatskovsky]

Hello Mojca,

Is there need for \strut at all? The definitions

\def\hotkey#1{\inframed[corner=00, offset=0pt]{\ #1\ }}

and 

\def\hotkey#1{\inframed[corner=00,offset=0pt]{\strut\ #1\ }}

work equally well and I can see no difference.

I (wrongly) supposed that \strut version can prevent the frame from growing in height, but when I set offset more then zero, the height is increased too.

In your original version, only the offset option was omitted, so that  frames was bigger by default. With offset=0pt they look just pretty.
(Until there are possibility to control width/height or xoffset/yoffset separately). 

Thanks a lot.

Best, 
Vyatcheslav

No. You get it by default unless you explicitely disable it. I just
didn't understand why you wanted to set the height explicitely.

Strut only prevents frame from shinking, not from growing. It's just
an invisible placeholder. If you provide higher material, the box will
grow.

\strut insures that all frames are of a minimimum height equal the 
height of parenthesis. Try

\hotkey{A} \hotkey{a}

What about:

\setupcolors[state=start]
\def\hotkey#1{\inframed[background=screen,offset=overlay,
  height=\lineheight,corner=00]{~#1~}}

(this is what I am using)

Re: Vertical alignment of framed text

[Vyatcheslav Yatskovsky]

Hello,

Please, don't take me as too much exacting man, but Mojca's (partial) solution

\def\hotkey#1{\inframed[corner=00]{\ #1\ }}

is more suitable for me than the Wolfgangs's (complete) one:

\defineframed
  [dohotkey]
  [strut=yes,corner=00,frameoffset=-0.2em,location=low]
\definehspace[hotkey][0.6em]
\def\hotkey#1{\dohotkey{\hspace[hotkey]#1\hspace[hotkey]}}   

The latter add space between surrounding words proportionally to the in-frame space.

The ideal solution would be 

\def\hotkey#1{\inframed[corner=00, location=low, height=\lineheight]{\ #1\ }}

but it doesn't work. Maybe it is a bug, ideed?

Best,
Vyatcheslav
