A GUI toolkit is a separate package that implements the gWidgets API. This function allows one to select the toolkit to be used by default.
guiToolkit(name = NULL)gtoolkit()
The name matches the package name without the initial gWidgets. For instance, "RGtk2" refers to the implementation provided by gWidgetsRGtk2.
The guiToolkit function returns a subclass of guiWidgetsToolkit that is
used for dispatching purposes by gWidgets. For example, the
method svalue dispatches on its first argument and the value
of the toolkit class stored in the toolkit slot of the object.
The gtoolkit function returns a character string for the toolkit.
Toolkits are named gWidgetsXXX. This function is used to get the toolkit class, or have the user select one. The gtoolkit function returns a string form of the toolkit. One way to set a toolkit is to use the guiToolkit option, as in options(guiToolkit="RGtk2").
# NOT RUN {
guiToolkit("RGtk2")
# }
