similar to: font test does not go higher than 49 - centos 4 x86_64

I have this really short script below that only lets me set the font size from 5 to 50 using the slider at the bottom. Anything higher than 50 it will not do. run the program as "wish -f file.tcl" Why can I not increase the font size - using the slider bar at the bottom to anything higher than 50??? Does this work for anyone else? Using xlsfonts there are sizes higher than 50. Jerry

I am running centos 4.x and 5 x86_64 and using the script below and the slider bar at the bottom I cannot get fonts bigger than 50. someone else posted a followup and said he has the same issue. What can be happening here??? xlsfonts shows that bigger fonts are available. How can I get bigger fonts??? Note - I had to do a "yum install tk" also... Thanks, Jerry

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 session > source("clrramp2.r") Loading required package: tcltk Loading Tcl/Tk interface ... done

Hello, i'm trying to translate following tcltk source code, which I found in newsgroup comp.lang.tcl, written by Tom Wilkason, into R Code. proc scrolled_Canvas {base} { frame $base.fm -borderwidth 2 -relief sunken canvas $base.fm.cv -yscrollcommand "$base.fm.cv_vertscrollbar set" scrollbar $base.fm.cv_vertscrollbar -orient vertical \ -command "$base.fm.cv

I have a simply script that I cannot get a font size bigger than 40. Changing the font_size value to 80 does not make the font any bigger just the background. How do I get a bigger font than 40? I run this script as "wish -f file.tcl" What am I doing wrong to not get bigger fonts? THanks, Jerry --------------------------------------------- set font_size 40 set show_window_title 0

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

Hello there, I'm struggling with the base graphics system on different operating systems. I would like to get an animation effect by re-plotting with the plot function. See the attached code example: move the slider quick from one side to the other. I experience different levels of success, depending on which OS I use. - Linux (Ubuntu >9.10, R 2.9.2-3): Each plot command gets

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

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? - Does anyone have an (informative) piece of

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

I noticed something strange in my app today. It appears that the 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 site: campaigns is a resource checkout is not # With the canvas false flag (rdb:1) @controller.url_for(:controller => ''campaigns'', :action => ''show'', :id

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 > x <- tkcmd("image", "create", "photo", file=mypic.gif)

Hi, I have two minor problems with scriptaculous sliders: a) when a list of allowed values is provided and that list contains 0 the value 0 is not usable This can be seen in the slider_test.html functional tests, slider 5 (multiple handles and predefined values), which allows values [0,0.2,0.4,0.6,0.8]. I cannot move any of the sliders to position 0 (using mozilla 1.7.8, same for

I have a ruby program that uses a FXCanvas, and I have attached a FXDCWindow to control it. It lets me draw lines, rectangles and ellipses, but not text. If I attempt to draw text, I get the following error This application has requested the Runtime to terminate it in an unusual way. Please contact the application''s support team for more information. >Exit code: 3 I also get this

I am currently in the middle of creating a horizontal scrolling product list with page buttons that use effects to scroll from one page to another using scriptaculous. I am having problem that when the window is resized, so only the viewable area of the div changes, this causes the width to change and then because of that the scroll effect will scroll to position 2000 but then when the scroll bar

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 instead of returning
