similar to: tk mouse cursor icon widget tkwinfo tkfocus questions

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 <-

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')

Dear All: I am stuck with this issue: I have a button on a TK window, once click it, it pops up a individual plot device: individual_plot <- function() { tkconfigure(overlay.button, state="normal") options(locatorBell = FALSE) plotfuntype() trellis.focus("panel", 1, 1,highlight=FALSE) panel.identify(labels=colnames(dataplot)) } Now I have

I searched the web and the list archives for a solution to this, but didn't see anything, so here goes. I'm new to tcltk. I'm trying to change the contents of a tkentry widget when a button is pressed. Once I get that working, the widget will be read only to the user. Here is some toy code: ############### require(tcltk) thisEnv=environment() tt<-tktoplevel() Name <-

Hallo! I want to test if a widget exists. Using Perl/Tk i can call the function tkexists(). How can I realise this function with R/tclTk ?

Dear all, I'm trying to use tcltk to build a small user-interface and couter the problem: It seems that sometimes the dialog box will be minimized automatically though I want it to be on top of the screen all the time. For example, when runing the following code, if you type in "a1", "a2", "a3", etc when being asked for an integer, the program is supposed to

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.)

Hello, I am sorry if this is an answered question, but I did my homework for a long while and couldn't figure out a way to retrieve data entry from a model dialog. In one of the examples compiled by James Wettenhall: odalDialog <- function(title, question, entryInit, entryWidth = 20, returnValOnCancel = "ID_CANCEL") { dlg <- tktoplevel() tkwm.deiconify(dlg)

I am the maintainer of a Bioconductor package (affylmGUI) which uses tcltk. It freezes inconsistently on MS Windows, but not Mac or Unix. see details below. After considerable testing I have reduced the problem from a few thousand lines of code to 30 lines! If you paste the following lines of code into an R window: testGUI <- function(){ require(tcltk) MainWindow <-

Dear all, please excuse the somewhat special question: >From within R I create a Tk windows with a list of checkboxes, which can bekome too long for the screen. The obvious solution would be to put all checkboxes into a frame and make that scrollable. Alas, there are (for whatever reason!) no scrollable frames in Tk :-( The usual workaround is to put widgets (my checkboxes) into a textbox,

Hey everyone - I recently switched to using a Mac and have several different rails projects going and was getting tired of starting/stopping mongrels via the shell so wrote my first dashboard widget to do it for me.

hi all. I''m planning a rails app and am wondering if anyone knows if there''s a javascript widget with the same functionality as dreamweavers ''point to file'' tool for those who have not seen this it is basically a small, four pointing arrow which you can click and hold on, and then drag and hold to a file or directory to select that file as a link

Just demo''d my app for marketing and they asked whether, on the big text fields, I could give a dynamic character counter so that as they approach the guideline maximum they''ll know. Seems like something that could be written by looking for key click events in the text field. Before I go writing one, though, I thought I''d check and see if anybody knows of such a

Hello all, I am trying to design a reusable widget content system, where I can easily lay out a bundle of widgets on a page and allow a user with proper administrative rights to click and change them. For the database storage, I don''t want to have to create a new table for every different classification of widget (ie, list, text body, image, etc). I would like to create a central

Hi! During developing my little program, I''ve noticed, that the objects have a hierarchy, but now I don''t know what to do, if a widget initiates an event which has an effect to the parent, grandfather/brother/other relatives. Is there a tutorial for this aspect? Gergo -- +-[ Kontra, Gergely<kgergely@mcl.hu> PhD student Room IB113 ]---------+ |
