In jverzani/gWidgetsWWW2: Toolkit implementation of the gWidgets API for use with web pages

Description

stack widget is a "card" container. Use gnotebook methods to change cards

Usage

gstackwidget(container, ..., width = NULL, height = NULL, ext.args = NULL)

Arguments

container	A parent container. In gWidgetsWWW2 a parent container is not optional (though it can be substituted with the parent argument in some circumstances). The parent specifies the widget heirarchy and the ... argument is used to pass along arguments to layout the child component in the parent container. Typically, these are passed to the add method of the parent container.
...	Used to pass along argument to the parent container's add method and possible other arguments to the underlying ference class constructors.
width	width in pixels of component. Sizing in gWidgetsWWW2 is sometimes necessary as the arguments expand and fill are not well implemented.
height	height in pixels of the component.
ext.args	The contructors of gWidgetsWWW2 ultimately call an Ext constructor. The options passed to the Ext constructor may be added to or overridden by use of this argument. Values are passed in as named list components and with values converted into JavaScript objects by asJSObject.

Value

a GStackWidget reference class object.

Examples

w <- gwindow()
sb <- gstatusbar("Powered by gWidgetsWWW and Rook", cont=w)
g <- gstackwidget(cont=w)
gbutton("page 1. Next", cont=g, handler=function(h,...) svalue(g) <- svalue(g) + 1)
gbutton("page 2. Next", cont=g, handler=function(h,...) svalue(g) <- svalue(g) + 1)
gbutton("remove me", cont=g, handler=function(h,...) dispose(g))
gbutton("page 3. First", cont=g, handler=function(h,...) svalue(g) <- 1)
svalue(g) <- 1
