similar to: gwidget position on screen

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?

I'd like to announce three new packages on CRAN: pmg, gWidgets, and gWidgetsRGtk2. --John Verzani 1 PMG *=*=*= The pmg package for R provides a relatively simple graphical user interface for R in a manner similar to the more mature RCmdr package. Basically this means a menu-driven interface to dialogs that collect arguments for R functions. This GUI was written with an eye towards

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 my handler would

Hi, I want to put a ggobi display into a GUI window setup by gWidgets, but error occur said it is not a S4 object. Does anyone have any idea about how to put it in or maybe it can not be put into a widget at all?

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? Below you find

Hello, I'm trying to make a graphical interface for an R function I've written. A common use for the function is to call it with specific parameters, and then watch the output as it evolves. There's not necessarily a logical stopping point, so I usually use ctrl-C when I'm done to stop it. I've made a gWidgets interface to the function that gets some user info and then on a

I have a layout in gwidgets. To this, I wanted to add a Textbox(gtkEntry) created from rgtk2... The code is as follows: MainLayOut <- glayout(homogeneous = FALSE, spacing = 10, container = SubGroup) MainLayOut[1, 1, anchor=left] <- "Number of Total Patients: " font(MainLayOut[1, 1, anchor=left]) <- c(weight="bold") patients <- gtkEntry()

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) addhandlerclicked(b, handler=function(h, ...){

Hi, For the past few months I've been building a simulation in R I hope to package. It consists of two usable functions, and many internal ones which one of the two usable functions call while looping, to perform the stages of simulation. A simple conceptual example is: # Abstract representation 1st Usable function, generates object containing settings for simulation. settings <-

Hi, how can I omit the box drawn from the starting position to the current position of the mouse when clicking and it over a GTK graphics object? I have seen that in the 'playwith' package the box changes to an arrow when using the 'pan' button. But I do not find the corresponding line in the code to implement that. library(gWidgets)

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,

I want to write a function mimic the function of select.list(), here is my preliminary version. select <- function(x,multiple=TRUE,...){ ans<-new.env() g <- gwindow(title=title,wid=200,heigh=500) x1<-ggroup(FALSE,con=g) x2<-gtable(x,multiple=multiple,con=x1,expand=TRUE) gbutton("OK",con=x1,handler=function(h,...){ value <- svalue(x2) if (length(value)==0)

I''m working on some schema for a new project that we''ll be doing in rails (our first rails project!). A recurring structure we are seeing is the desire to define an ordering any way we wish, so ''acts_as_list'' comes to the rescue. But, the ''position'' column seems to need to belong in the join table to make sense. For example, we have

All: Using gWidgetsWWW, I'm in the process of designing a website that will provide users with a GUI to interact with various datasets. As part of that, I want to provide users the ability select particular variables (via combo boxes) that will then result in summary (text) output being returned to the webpage. Think of it as their choices ultimately result in a one- or two-way table being

Hello R lovers, For my GUI, I am using gslider of Gwidgets. I need to add the "to=" value dynamically ie., maximum value from a data frame column(something like to=max(df[,3])). But I am getting error message like Error in checkPtrType(object, "GtkWidget") : object of class NULL isn't a GtkWidget Not sure what I am missing here!!! Regards, karthick -- View this

Dear John, Actually, I was using gWidgetsRGtk2. The solution you suggest works fine. Thank you very much. Best regards. Olivier -- ____________________________________ Olivier G.
