Hi, I've been learning how to use R TclTk in Windows over the last few months. I have recently put together a collection of examples of some common widgets and their corresponding R code, at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ I would be interested in any feedback - Is it useful? Does it contain any significant errors or bad coding style? Does anyone else want to

I can set up an entry widget (thanks to an old post by Barry Rowlingson) that gets a password and exits when the user clicks on the "OK" button. Anyone have any clever ideas for returning/ destroying the window when the user types a carriage return/ENTER in the text window? I've messed around a little with validate, validatecommand, but don't see any obvious way to do it ...

Hi - I'm creating a package of database tools. A function in the package requires the username and password as input to the function in order to initially connect to the target database(s). Of course, this poses a significant security issue given the possible retention of the function statement in cleartext. I did not readily encounter a package meant to mask input from the user nor do I

Hello, I'm very much a newbie in R and more so in tcltk so apologies if this question is stupid. Basically I am trying to use the combobox example found here: http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/DropDown.html .

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.

Hi, all, (sessionInfo at the end) I've been struggling with the tcltk package and can't seem to get the ttkcombobox to work.

How do I know when the value of the combobox has

I am struggling with adding menus to a tcltk application. The following example (from the O'Reilly book on Perl/Tk) works fine: #!/usr/bin/perl -w use Tk; my $mw = MainWindow->new; $menub = $mw->Menubutton(-text => "Color")->pack(); foreach (qw/red yellow green blue grey/) { $menub->radiobutton(-label => $_, -command => \&set_bg,
