similar to: using yscrollcommand in tkcanvas crashes R (PR#13231)

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)

Dear R-devel list members, I've encountered a problem with my Rcmdr package under Windows XP and could use some advice: The Rcmdr package uses the tcltk package to create menus and dialog boxes. My standard procedure when a dialog is created is to grab the focus -- e.g., by tkfocus(top) tkgrab(top) (Here, top is a top-level window -- say, containing one or more scrollbars.)

Dear list members, Rich Heiberger reported to me last week that the Messages window in the Rcmdr GUI was freezing -- that is, messages posted to this window didn't appear -- under Windows and R 2.8.0. I was able to confirm this problem on three Windows systems, one using Vista and the other two XP. In each case, I used R 2.8.0 and Rcmdr 1.4-4 (the current version). The problem doesn't

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

The following code should give me (at least that's what I think) two list boxes with their individual scrollbars. But instead both scrollbars stick to the same listbox even though they work as they should (scroll individual listboxes). When I remove all the widgets on top everything works perfectly. Any help would be highly apprecciated. ps: all subsequent listboxes and scrollbars work

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

I've been able to figure out on my own how to do what I need in the largely undocumented tcltk package, but I've finally hit a wall. I can't even think of any sufficiently specific search terms to use for this. I'm trying to make the widgets in my tk window resize when the window is resized by clicking and dragging on its corners or edges. Instead they stay exactly where they

I like to monitor simulation by reporting some current values to the console, every 25th iteration say. I think it might be nice to have that appear in a separate window. Anyone know how? regards, David Farrar New River Analytic [[alternative HTML version deleted]]

I everyone, i have a little problem with tklistbox,the " " character and Rcmdr. Please look at this code require(tcltk) tt<-tktoplevel() levels.list2 <-tklistbox(tt,selectmode="multiple",exportselection="FALSE", height=4, yscrollcommand=function(...)tkset(levels.list2.scroll,...))

Hi there, a text Window is supposed to map the shortcuts for copying and pasting (<Ctrl-C>, <Ctrl-V>) automatically. I'm working under Mac OS X and my text window doesn't really map these functions automatically - it works fine under Windows. Is there an easy way to map copy&paste functions to a text window under Mac OS X? This is what I'm doing with my text

Sorry, for my mail from last night contains no subject. Therefore, I send it again and two tcltk questions are appended. ---------------------------------------------------------------------------- Prasad wrote: > I wrote a function in R which uses tcltk package .... essentially I wanted > to give within that function, a widget with 2 radiobuttons to choose > between plotting Precip

Can anyone show me how to connect a scrollbar to a text widget using the tcltk library? I'm confused about how to make sure the two widgets know about each other and how to set up the appropriate call-backs for scrolling.

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

Dear list members, Is it possible via a suitable tcltk command to get the *current* width, in characters, of a Tk text widget that has been resized with the mouse? In the following code, the reported width of the text widget doesn't change, even though it has been resized. I can, however, get the current width in pixels: > library(tcltk) > top <- tktoplevel() > textWindow <-

Hello, everyone. I have the following problem with TclTk: I create some windows and want to change their position with geometry manage (sometimes they will be centered, sometimes not). If the toplevel is created and its dimensions are gathered via 'tkwinfo', I get (usually) correct values. However, if this window is created by a function (in the following example, by 'ask.format')

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: mainFrame <-

Hi, I think that R-tcltk doesn't have the capacity to display an image stored in memory on a tkcanvas object, am I right? I have digged around everything I can find from Peter Dalgaard and tcltk references and drew my conclusion. Can you, Peter, or some other gurus on the list, give us a pointer or two on how to proceed to solve this problem? I am afraid that it may involve writing C

Hi, I've been playing with the tcltk package. It's very nice to have access to buttons, menus etc. now. Thank you! Alas, I also have questions: In Tcl everything is a string [*]. This is not the case in R, of course. So why are return values of tk commands still strings? (Is there any other reason than speed or "package is work in progress"?) Example: > tt <-
