Constructor of box container widget with disclosure trigger and label

generic for toolkit dispatch

For gexpandgroup, the visible assignment method is overridden to change the disclosure state

The change handler for a expandGroup is called when the group changes visibility

gexpandgroup(text = "", markup = FALSE, horizontal = TRUE,
  handler = NULL, action = NULL, container = NULL, ...,
  toolkit = guiToolkit())

.gexpandgroup(toolkit, text = "", markup = FALSE, horizontal = TRUE,
  handler = NULL, action = NULL, container = NULL, ...)

## S3 replacement method for class 'GExpandGroup'
 visible(obj) <- value

## S3 method for class 'GExpandGroup'
addHandlerChanged(obj, handler, action = NULL, ...)

`text`	Label text
`markup`	logical. Does text have markup? (Toolkit dependent: only implemented for `RGtk2`, in `qtbase` one can pass HTML formatted text)
`horizontal`	horizontal (`TRUE`) or vertical packing.
`handler`	handler called when state is toggled
`action`	passed to handler
`container`	parent container
`...`	passed to parent's `add` method
`toolkit`	toolkit
`obj`	object receiving event and emitting a signal to the handler
`value`	logical. If `TRUE` show, `FALSE` hide.

An object of class GExpandGroup inheriting from GFrame

ggroup and gframe

 if(interactive()) {
    w <- gwindow("Box containers")
    g <- gvbox(cont=w)                         # ggroup(horizonta=FALSE, ...)
    nb <- gnotebook(cont=g); gbutton("one", label="one", cont=nb)
    gframe("Frame", cont=g)
    pg <- gpanedgroup(cont=g);
    gbutton("one", cont=pg);
    gbutton("two", cont=pg)

    eg <- gexpandgroup(cont=g, horizontal=FALSE);
    glabel("Click above to hide", cont=eg);
    gbutton("one", cont=eg);
    gbutton("two", cont=eg)
}
