## Constructors for widgets to handle text input

### Description

The ghtml widget is intended to show HTML text either from a url or from a character string. Currently no toolkits support this widget, although it is in gWidgetsWWW.

### Usage

    ghtml(x, handler = NULL, action = NULL, container = NULL, ..., toolkit = guiToolkit())

### Arguments

`x` | url or HTML-marked up character string to load into widget.
`handler` | (In theory, not implemented yet) Handles a click on a URL. The default is to open the clicked url in the widget. To override, the first argument, a list `h`, has component `h\$url` containing the url.
`action` | Passed along to the handler as `h\$action`
`container` | Optional container to attach widget to
`...` | Passed to `add` method of container
`toolkit` | Which GUI toolkit to use

### Details

This widget loads the given url into a widget. Currently no toolkits support this.

The `svalue` method returns the current url or character string.

The `svalue<-` method loads a url or character string in the widget.
