tcltk, X11 protocol error: Bug?
Hi,
I am having trouble debugging this one. The code is attached below, but
it seems to be a problem at the
C-tk interface. If I run this 1 time there are no problems if I run it
more than once I start to get warnings
that increase in multiples of 11 everytime I run it. Here is a sample

Drawing a graph with vertices and edges using tcl/tk
Dear all; I would like to draw a graph with vertices and edges, and I guess tcl/tk would be appropriate. I don't know tcl/tk but have googled for a 10-page (or so) introduction to 'getting started with tcl/tk in R' but without any luck.
- Does anyone know of the existence of such a document or any other web-based material on the subject?

Difficulties with R.oo (static fields, etc.)
I would like to use R.oo and tcltk to implement a Turtle World. I have
encountered
many problems because:
1) I am not sure how to implement static fields with R.oo
2) I am not sure how to implement a constructor that would
call a function only for the first instance of a class (i.e., to
initialize
value of static fields only once)
3) I am not sure how to remove/delete cleanly existing

GUI component Margin on tkcanvas, tkframe or tktoplevel
Dear gurus:
I have a question on how to configure the margin layout on tcl/tk GUI
objects like tkcanvas, tkframe or tktoplevel.
For example, if I want to leave a larger margin on the left side of the
GUI container, which one should I configure, the toplevel or tkcanvas or
tkframe?
top<-tktoplevel()
canvas<-tkcanvas(top, relief=, borderwidth=...)
I also find the documentation for all

Is it possible to pass a Tcl/Tk component as argument to a function
hi! All:
I wonder if someone has done this before...
I am writing several functions that conduct statistical analysis using a
GUI interface by Tcl/Tk, they share many identical GUI components. What
I am trying to do now is to simplify the code by writing a GUI
repository for all the components they use, thus save effort for code
maintenance.
Since they all use:

Scrolling a tkcanvas non-starter
Hello,
Is it possible to scroll a canvas that has a column of listboxes in it? Does scrolling only work with listboxes and text widgets?
The following code displays the scrollbar, but
- it has no thumb
- does not respond to mouse clicks.
- the vertical height of the tkcanvas (i.e. column1) is unconstrained. It's lower edge is out of view, and the lower button on the scrollbar is out of

gif, jpeg and png image files reader AND tcltk image
Hi all,
Roger Peng and Jason Turner's suggestion with ImageMagick seem to be the
simplest "dirty" way
to get the problem solved.
But I ran into yet another interesting but quite round-about way to solve
the problem (partially). Through tcltk package, one can read in the gif
image with

tkcanvas/bitmap for Turtle World
To represent a turtle inside a canvas (tcltk package), I have a serie of
bitmaps
representing the turtle heading in different directions and I would like
to display the one that corresponds to the current direction of the turtle
(function below).
I have created with Paint a bitmap representing the turtle in BMP format
and succeeded displaying it on canvas after converting it into XBM format

Perhaps someone here can help.

Installing R on Red Hat Linux, Tcl/Tk
Hi,
I've been trying to install R on Red Hat Linux 9 for some
potential users of my R/TclTk application. I tried using the
rpm for R 1.7.1 for Red Hat Linux 9. It told me that I needed:
libtcl8.3.so
so I looked for a binary release of Tcl 8.3.x on
http://www.tcl.tk/software/tcltk/8.3.html
but found that the link to the Tcl 8.3.x binaries pointed to
ActiveTcl 8.4.x . I couldn't see

Most of us started from the handful of examples you can see via
demo("tcltk")
There are also some good examples in the mailing list archives
though some of the R to Tcl/Tk interfaces changed slightly in
recent releases.

url_for + :canvas => false weirdness for non resource controllers

extra canvas path appended in url_for is back but only for
controllers that are not resources. Here is an example I have in my

Dynamic resize of drawing canvas and FXImage
How can I use the drawing canvas and its off-screen image buffer, say
FXImage, to dynamically resize or have its width and height attributes
changed in reply to user interaction with the main window (FXMainWindow)?
It seems that whem I put initial values to W and H of the canvas or FXImage,
they remain with its initial values no matter what I do whem resizing the
main window.

Canvas Tag + Rails Ajax
Hi all,
Just looking for a quick sanity check. I was thinking of writing a
plugin for rails to give rails developers a good way of using the new
firefox 1.5/safari canvas tags. I was thinking of grabbing an
existing ruby graphics library and modifying it so that it renders
via the canvas tag..
So you could have link_to_remote pointing to controller actions that
