minimal button width

minimal button width

[Peter Rolf]

I want some small empty buttons with exact dimensions. Is there a way to do
this with \button or must I use fields (ughh) instead?

\setupbuttons[strut=no, offset=overlay, framecolor=green, empty=yes]

The minimum width of a button depends on the actual bodyfont size.
I'm sure that there are good reasons for it.

\switchtobodyfont[20pt]
But I want smaller {\bf empty} \textreference[test]{test}buttons!
\button[width=25mm, height=2.5mm]{Please, print me!}[test]
\button[width=2.5mm, height=25mm]{Not this time!}[test]
\blank[big]

\switchtobodyfont[40pt]
Help at 40pt...
\button[width=25mm, height=2.5mm]{Now?}[test]
\button[width=2.5mm, height=25mm]{Nope!}[test]

Hello Peter,

with your code + 

\button[width=2.5mm, height=2.5mm]{Please, print me!}[test]
\button[width=2.5mm, height=2.5mm]{Not this time!}[test]

I get two empty square buttons which look about 2.5 mm wide and high. I
could send you a screenshot or the resulting pdf file.

I tried the ConTeXt version 2003.9.24. But maybe I don't understand
your question.

one value should be 25mm for a better example

Just press the buttons (not releasing the left  mouse button) and you 
will see...

Just to confirm: in normal state I see a small button. When pressing
the mouse button I see the area of the button inverted but with more
width than actually used, but the height looks fine.

+---+            xxxxxxx+---+xxxxxxxx
|   |  becomes   xxxxxxx|xxx|xxxxxxxx
+---+            xxxxxxx+---+xxxxxxxx

where xx is inverted. But this happens (in your example) only with
the 2.5 mm width. The 25 mm wide button is OK.

confirmation granted; nice ascii example!
What you see is not only the inverted but the whole size of the button. 
You can activate this button
in this visible area (and that's my problem).

Yep! The 2.5mm wide button is smaller than the minimum given through the 
actual font size,
while the 25mm wide button is not. If I for example use 
\switchtobodyfont[5pt] in front of
the button definition, I can get a 2.5mm wide button.
Sorry for irritating you, but the function of a button is not to rule a 
frame. ;-)

    Peter

It seems you haven't followed the discussion with Patrick. You are the 
second one,
who has trouble to understand my problem. I'll try to be more precise in 
the future. :)

It's not the size of the printed part (frame). My problem is the 
activation area
(this is what I mean with size) of the button. For the default font (12pt)
the minimal wide of an *empty* button is about 4.15mm, if you use bigger 
fonts
this value increases. Just push the buttons (not releasing the left 
mouse button)
in my example and you see what I mean.

   Peter
