RGtk2 - retrieve ggraphics mouse coordinates during drag-and-drop event
Hi all,
I have a gtable and a ggraphic widget.
I want to drag an element from the table onto the graphic.
When the drag object is released over the ggraphic widget, I want the
mouse coordinates inside the ggraphic to be returned.
Right now I do not know how to get the mouse ccordinates of the
ggraphic widget at any given time.
How can I access the ggraphics mouse coordinates?

RGtk2 / gWidgets - addHandlerClicked Problem
In The following code, the table handler is executed twice when the
button is pressed (from the 2nd pressing on).
I want it to be executed only once. Does someone know, why this
happens and how I can change it?
library(gWidgets)
w <- gwindow()
b <- gbutton("press", cont=w)
tbl <- gtable(1:10, cont=w)

gWidgets / RGtk2 - how to change a handler from a toolbar?
I want to assign a default handler to a toolbar button and change the
handler later.
The addhandlerclicked() method does not apply to a gAction Object, I
think...
defHandler <- function(h, ...) print("default")
w <- gwindow()
aTest <- gaction(label="Test", icon="open", handler=defHandler)
tblList = list( test = aTest )
toolBar = gtoolbar(tblList,

gWidgets (tcltk): problem extracting values from widgets in glayout grid
Hello,
I haven't been able to find an example for the second case below -- or
perhaps I didn't recognize it when I saw it.
Is there a value for x such that svalue(x) will return "bbb", either by
itself or as part of an array? Or do I need to do something else
entirely?

How do I define the method for gcheckboxgroup in gWidgets?
Hi All...
I?m trying to build a small demo using gWidgets which permits interactive
scaling and selection among different things to plot. I can get the widgets
for scaling to work just fine. I am using gcheckboxgroup to make the
(possibly multiple) selections. However, I can?t seem to figure out how to
properly define the gcheckboxgroup; I can draw the widget properly, I think

RGtk2: How to overlay a gtkDrawingArea with a button or any other widget?
I try to overlay a plot inside a gtkDrawingArea with a button (or any other widget).
I tried to put both into a gtkFixed container.
But this does not work, no printing occurs.
Does someone know a solution?
What I tried:
w <- gtkWindow()
w$setSizeRequest(400,400)
fx <- gtkFixed()
da <- gtkDrawingArea()
fx$put(da, 100, 100)
asCairoDevice(da)

Reordering the results from table(cut()) by break argument
I have a vector and need to count how many data points fall inside
each bin:
dat <- rnorm(100)
breaks <- -3:3
table((cut(dat, breaks)))
(-3,-2] (-2,-1] (-1,0] (0,1] (1,2] (2,3]
3 13 42 30 12 0
if I reverse the breaks vector, the results remains the same:
breaks <- rev(breaks)

no partial matching of argument names after dots argument - why?
I noticed that the argument names after the dots argument are not partially matched.
foo <- function(one, two, ...){
one + two
}
> foo(o=1, t=2)
[1] 3
foo <- function(one, ..., two){
one + two
}
> foo(o=1, t=2)
Fehler in one + two : 'two' fehlt
Can someone explain me the reason for this behavior?

changing a list element's name during execution in lapply - possible?
Happy New Year, all!
I want to do calculations on each element of a list l, but i want the
returned list element to be named differently after the calculation.
Is it possible to do the renaming somehow within the lapply call?
l <- list(a=NA, b=NA)
lapply(l, function(x) {names(x) <- "new name"; return(x) })
This does not work, any ideas?

When using a gtkDrawingArea as a Cairo device I very often encounter the error: "figure margins too large"
Even for the below "getting started" example from http://www.ggobi.org/rgtk2/ this is the case.

changing the drawing context using Cairo and RGtk2
I am not too familiar with Cairo and RGtk2 and have the following problem:
I have a container with two GTK drawing areas converted into Cairo devices.
I know that I can set the current drawing context e.g. using dev.set().
But this is tedious. How can I set the context using the objects da1 or da2?
w <- gtkWindow()
w$setSizeRequest(400, 400)
vbox <- gtkVBox()
da1 <- gtkDrawingArea()
