The row for D.but should be 2, not 3 though I would index at 0 not 1:
tkgrid(A.but,row=1-1,column=1-1,columnspan=2,rowspan=2,sticky="nswe")
tkgrid(B.but,row=3-1,column=1-1,columnspan=2,rowspan=1,sticky="nswe")
tkgrid(C.but,row=1-1,column=3-1,columnspan=2,rowspan=1,sticky="wens")
tkgrid(D.but,row=3-1-1,column=3-1,columnspan=2,rowspan=2,sticky="wens")
Then to get the buttons to expand into the allocated sace, you can configure
the row and column weights:
sapply(0:3, function(i) {
if(i < 3) tkgrid.rowconfigure(tt, i, weight = 1)
tkgrid.columnconfigure(tt, i, weight = 1)
})

Can you check if the following runs? It worked for me so it may be
an older version (on gWIdgetsRGtk2 and gWidgetstcltk)
w <- gwindow(visible=FALSE)
g <- ggroup(cont=w, horizontal=FALSE)
tbl <- gtable(mtcars[1:5,], cont=g, multiple=TRUE, expand=TRUE)
b <- gbutton("click", cont=g, handler=function(h,...) {
print(svalue(tbl))
})
visible(w) <- TRUE
svalue(tbl, index=TRUE) <- 1:2
print(svalue(tbl, index=TRUE))
You should see 1 2 on the console and the first and second rows
should appear selected.

Greg is right. You might try validating on focusout, rather than the key,
but this is easy enough to do in R code, rather than let tcl do that work:
a <- 306870; b <- 3026741
tt<-tktoplevel()
varalpha <- tclVar(a)
charalpha <- tclVar(as.character(a))
scale <- tkscale(tt, from=a, to=b, resolution=1, label="alpha",
variable=varalpha,
showvalue=TRUE, orient="horiz")
ed <- tkentry(tt, textvariable=charalpha)
tkpack(ed)
tkpack(scale)
## connect
tkconfigure(scale, command=function(...) {
tclvalue(charalpha) <- as.character(tclvalue(varalpha))
})
valid_input <- function(...) {
val <- as.numeric(tclvalue(charalpha))
if(a <= val & val <= b) {
message("set to ", val)
tclvalue(varalpha) <- val
} else {
message("not valid...")
tkfocus(ed)
}
}
tkbind(ed, "", valid_input)

In the handler just add the call dispose(A).

The following shows how you can do this. The main answer is
use svalue<- to set the contents of the gtext area, or use
insert() to append text.
library(gWidgets)
options(guiToolkit="tcltk")
w <- gwindow("output", visible=FALSE)
g <- ggroup(cont=w, horizontal=FALSE)
g1 <- ggroup(cont=g)
input <- gedit("", cont=g1, expand=TRUE)
btn <- gbutton("run", cont=g1)
output <- gtext("", cont=g)
visible(w) <- TRUE
run <- function(h,...) {
val <- svalue(input)
svalue(output) <- as.numeric(val) + 1
}
sapply(list(btn, input), addHandlerChanged, handler=run )

You are much better off pointing out this uses the traitr package,
as otherwise one wouldn't know where to begin. In this case,
there isn't a straightforward way, but this hack will let you do it:
size(aa$widget_list$toplevel) <- c(600, 600)
I haven't worked on that package for awhile, as it didn't get many users.

There are two ways. You can use a buttonItem or to add a button to a dialog,
just use the buttons property and define a handler. Here are both in an example:
dlg <- aDialog(items=list(a = buttonItem("click me", show_label=FALSE,
action=function(.,...) print("clicked"))
),
buttons=c("OK","Cancel","Help","Some other"),
Someother_handler=function(.) print("some other button"))

I'm just guessing, but you might try this for your OK_handler:
OK_handler=function(.) {
pdb <- read.pdb(.$get_ProteinCode())
}
(Or use yours, but drop the quotes around "ProteinCode".)
That doesn't modify pdb outside the scope of the handler, so likely you need to
do something else with it.

The playwith solution is shorter but this GUI mockup using gWidgets might be
more flexible:
library(gWidgets)
make_plot <- function(i, ...) {
## your plot goes here
cat(i)
plot(1, i)
}
do_something <- function(i,..) {
cat("clicked on", i, "\n")
}
w <- gwindow("Plot example")
g <- ggroup(cont=w, horizontal=FALSE)
i <- gslider(from=2, to=100, by=1, cont=g, handler=function(h,...) {
make_plot(svalue(h$obj))
})
b <- gbutton("do something", cont=g, handler=function(h,...) {
do_something(svalue(i))
})
That will work with tcltk and RGtk2. If you have RGtk2 installed, then you might
also like this GUI template using traitr:
library(gWidgets)
options(guiToolkit="RGtk2")
require(traitr)
dlg <- aDialog(items=list(
i=rangeItem(value=2, from=2, to=100, by=1),
g=graphicDeviceItem()
),
buttons="Details...",
property_i_value_changed=function(., value, old_value) {
make_plot(value)
},
Details_handler = function(.) {
do_something(.$to_R()$i)
})
dlg$make_gui()

Here is some code to grab the display for a new display. I don't know
how to get the initial display or even how to suppress it, but I'm
not a ggobi user at this point.
library(RGtk2)
library(rggobi)
library(gWidgets)
options(guiToolkit="RGtk2")
x <- ggobi(mtcars)
## not sure how to get the initial display,
## here we create a new display and move that
disp <- display(x[1]) ## see display.GGobiData
## find table in the display heirarchy
table <- disp[[2]]
## plot is third child (rulers are first two)
plotWidget <- table[[3]]$getWidget()
table$remove(plotWidget)
## hide window that held display. Destroy() causes errors
disp$getParent()$hide()
## now we need to declass things so that gWidgets will
## recognize. The S3 classes from RGtk2 that gWidgets
## knows about are declared in package (should be
## dynamic, but aren't)
class(plotWidget) <- class(plotWidget)[-(1:3)]
w <- gwindow("A gwidget's window")
g <- ggroup(cont = w, expand=TRUE)
add(g, plotWidget, expand=TRUE)

To embed a GTK widget into gWidgets isn't too hard, just call the add method.
I'm not sure how to get the GTK object you want from the ggobi
interface. Below is an example that you might be able to modify:
##
library(RGtk2)
library(rggobi)
library(gWidgets)
options(guiToolkit="RGtk2")
## ggoobi object
x <- ggobi(mtcars)
## grab child from main window. Modify (how?) to get
## other widgets
toplevel <- ggobi_gtk_main_window(x)
child <- toplevel[[1]] # toplevel has only one child
toplevel$remove(child) # remove child if keeping toplevel
toplevel$destroy() # or destroy if not
## add to a gWidget instance using gWidgetsRGtk2:
w <- gwindow("A gwidget's window")
g <- ggroup(cont = w, expand=TRUE)
add(g, child, expand=TRUE)

Personally, I'd go with Rpad. To add to the FAQ that Dirk quotes: The Sage project has an online "notebook" server at sagenb.org that allows one to use numerous open source math programs including R. Sage can be installed locally as well. (The R feature seems to be broken at the moment though, but it does work on a local install.) The gWidgetsWWW package (needs testing still) provides an interface to Rpad that you could use to quickly create a web page to interpret R commands, e.g. the simplistic http://www.math.csi.cuny.edu/gWidgetsWWW/ex-cli.html. However, graphics are easier done using Rpad, than gWidgetsWWW. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

This is now fixed for RGtk2 as of version 0.0-29 (which was just uploaded to
CRAN). I'm not sure font<- alone does what you want. It only changes colors.
You might need to look at RGtk2's gtkTextBufferRemoveTag to remove colors.

The svalue method has the index argument for the widgets where you might want to
return the index or value such with a radio button group or combobox. For
gtext, the drop argument when TRUE returns just the text selected by the mouse,
otherwise the entire text buffer is returned.
library(gWidgets)
options("guiToolkit"="RGtk2")
obj = gtext("sadfsad",cont=T)
svalue(obj) ## returns: "sadfsad\n"
svalue(obj,drop=TRUE) ## returns ""
## now highlight some text
svalue(obj,drop=TRUE) ## returns "dfsa"
If you want to email me a bit more detail as to what you are trying to do, I can
let you know if gWidgets can work for you.
