tkStartGUI {tcltk} | R Documentation

## Tcl/Tk GUI startup

### Description

Starts up the Tcl/Tk GUI

### Usage

    tkStartGUI()

### Details

Starts a GUI console implemented via a Tk text widget. This should probably be called at most once per session. Also redefines the file pager (as used by `help()`) to be the Tk pager.

### Note

`tkStartGUI()` saves its evaluation environment as `.GUIenv`. This means that the user interface elements can be accessed in order to extend the interface. The three main objects are named `Term`, `Menu`, and `Toolbar`, and the various submenus and callback functions can be seen with `ls(envir=.GUIenv)`.
