### Arguments

`parent` | Parent of widget window.
`type` | string describing the type of widget desired.
`...` | handled via `.Tcl.args`.

### Details

These functions create Tk widgets. `tkwidget` creates a widget of a given type, the others simply call `tkwidget` with the respective `type` argument.

The functions starting `ttk` are for the themed widget set for Tk 8.5 or later. A tutorial can be found at http://www.tkdocs.com.

It is not possible to describe the widgets and their arguments in full. Please refer to the Tcl/Tk documentation.

### Examples

    ## Not run:
    ## These cannot be run by examples() but should be OK when pasted
    ## into an interactive R session with the tcltk package loaded

    tt <- tktoplevel()
    label.widget <- tklabel(tt, text = "Hello, World!")
    button.widget <- tkbutton(tt, text = "Push",
                              command = function()cat("OW!\n"))
    tkpack(label.widget, button.widget) # geometry manager
                                        # see Tk-commands

    ## Push the button and then...

    tkdestroy(tt)

    ## test for themed widgets
    if(as.character(tcl("info", "tclversion")) >= "8.5") {
      # make use of themed widgets
      # list themes
      as.character(tcl("ttk::style", "theme", "names"))
      # select a theme -- here pre-XP windows
      tcl("ttk::style", "theme", "use", "winnative")
    } else {
      # use Tk 8.0 widgets
