R: A GUI object

gui {svGUI}

R Documentation

A GUI object

Description

The 'gui' object contains and manages GUI-related data.

Usage

## S3 method for class 'gui'
gui$x, args
## S3 method for class 'gui'
print(x, ...)
is.gui(x)

Arguments

`x`	a function for `$`, or an object for the others.
`gui`	a 'gui' object.
`args`	arguments to pass to the function.
`...`	further arguments (not used yet).

Details

Methods for 'gui' objects can dispatch as usuang using amethod(...., gui = agui) but note that these methods do not dispatch on first provided argument, but to the named argument gui. There is another way to call 'gui' methods: agui$amethod(....). This may be a convenient alternative for those who prefer this style of calling object's methods.

Value

The result of the evaluation of the method of function applied for agui$amethod(....). The 'gui' object, invisibly, for print(). TRUE for is.gui(x) if the object x inherits from 'gui', FALSE otherwise.

Note

The 'gui' objects are not terribly useful by themselve, but thay provide the fundation for a flexible organisation of GUI elements in R (see for instance svDialogs or svWidgets).
