similar to: tcltk resizing when using tkgrid for layout

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 <-

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)

Hi everybody, I have a problem with the grid function in tk. I juste try to put 4 buttons like this: ------------------- | | | | | C | | A |--------| | | | ---------- D | | | | | B | | ------------------- A is 2x2 C is 1x2 B is 1x2 D is 2x2 but the code bellow dont work : require(tcltk) tt <-

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

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

In Windows, Tcl/Tk programs running under the tcltk package can update too frequently: for exmaple, we might go through a long sequence of operations to construct a complex display, and in Windows each addition will be shown separately. To work around this, I've added a function "tclServiceMode" which serves as an R interface to the "Tcl_SetServiceMode" function in the

Hi there, I need to build up a tktext-widget that contains a longer text than the tktext-widget actually is. So what I mean is, that the tktext window is of width=100 and the text in it has a length greater 100. But I don't want the window to just wrap the line, but to belong to scrollbar that is able to scroll to the end of the text. tt <- tktoplevel() txt <- tktext(tt,

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

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

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.)

Hey folks, This is my first message to the mailing list so please let me know if I mess something up. I'm trying to use the selectcommand for the mclistbox but I'm not very adept at using functions. Ideally I'd like to change the editor text when a different list item is selected but any help using the selectcommand would be appreciated and I think I could get the rest working.

Dear list, I have multiple (BWidget) listboxes in the same toplevel window. The problem is, if I select (by left clicking) on one of those listbox elements, the current selection in the *other* listboxes is cleared! Anybody knows how I can prevent this? Here's my code (sorry not complete): (E.g. If I select an X value, I'd lose the Y value I selected before) gui.create.tab.general <-

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]]

We have recently migrated from CentOS6/Gnome to CentOS7/Mate - and have noticed 'glitches' with some Qt applications that appears to be linked to the 'org.mate.Marco.general' 'compositing-manager' setting - and wondered how we 'fix' the issue ... Below is a PyQT4 python script that shows the issues: 1. With 'compositing-manager' set to 'true' (I

Hello companions!!! I have a function that creates a Radio Buttons, and I need that this function return the selected value in the Radio Buttons. I would like that, if somebody know as I could return the value, you say me as do it. Next, I show the function function1<-function(){ require(tcltk) tt <- tktoplevel() rb1 <- tkradiobutton(tt) rb2 <- tkradiobutton(tt) rbValue <-

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')
