Hi everybody here.
I'm new to programming but I was so delighted with
vtcl that I started some small application to connect
with some hardware prototypes that use tcl as
underware interface connection with the firmware of
those prototypes.
The point is that this small app has a main window
with two text boxes, first is an input console and
second is an output console. Both are having their own
scrollbar and I would like them to be always on its
lowest (bottom) position because text and answer is
always added to the existent inbox-text and people has
to move the scrollbar down manually.
The "y scroll cmd" on text boxes is using:
scrollMove .top17.scr24
and the scrollMove procedure is defined as:
# scrollMove --
# Sends to the plotter a file without evaluating.
# Suited for sending draws to the plotter.
#
# Arguments:
# scrollbar - Name of the scroll windget.
# first - x axis argument.
# second - y axis argument.
$scrollbar set $first $second
The scrollbar command is:
.top17.tex23 yview
Does all that make sense? I hope so. Well, that works
and allows to move up and down the content on the text
widget sincronized with the content of the text box.
So, to sum it up, the question is: how can I do that
the scroll bar pointer was always at bottom position,
so, displaying last lines of the text widget (instead
of always at top displaying always first lines)?
Thanks in advance.
