The svalue method has the index argument for the widgets where you might want to return the index or value such with a radio button group or combobox. For gtext, the drop argument when TRUE returns just the text selected by the mouse, otherwise the entire text buffer is returned. library(gWidgets) options("guiToolkit"="RGtk2") obj = gtext("sadfsad",cont=T) svalue(obj) ## returns: "sadfsad\n" svalue(obj,drop=TRUE) ## returns "" ## now highlight some text svalue(obj,drop=TRUE) ## returns "dfsa" If you want to email me a bit more detail as to what you are trying to do, I can let you know if gWidgets can work for you. --John > > 2008/1/21, Gabor Grothendieck <ggrothendieck <at> gmail.com>: > > > > You can find examples of using tcltk here: > > > > http://www.sciviews.org/_rgui/tcltk/ > > > > Also the gwidgets package is a toolkit independent > > layer that can run on top of tcltk or RGtk and it is described > > with many examples here: > > > > http://wiener.math.csi.cuny.edu/pmg/gWidgets > > > > On Jan 21, 2008 4:02 AM, ronggui <ronggui.huang <at> gmail.com> wrote: > > > What I want to do is: > > > 1, creat a text box, insert text into that box. > > > 2, select chunk of of the text by mouse, and link it to a lable. so I > > would > > > like a way to get that chunk of text. > > > > > > Can I do such job with tcltk?
