gslider: slider widget

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

Description

Use slider to select from a sequence of values, specified as with seq. The sequence steps must be greater than 1

Usage

  gslider(from = 0, to = 100, by = 1, value = from,
    horizontal = TRUE, handler = NULL, action = NULL,
    container = NULL, ..., width = NULL, height = NULL,
    ext.args = NULL, tpl = "{0}")

Arguments

from	starting point. Unlike other implementations for gWidgets, this is not possibly a vector specifying a range of values to slide over.
to	ending point
by	step size. Must be larger than 1 and even then will round to integer value
value	initial value
horizontal	orientation
tpl	Template for tooltip. Should have "{0}" to replace the value, but can have more formatting
handler	optional handler bound via addHandlerChanged
action	optional value to paramaterize handler
container	parent container
...	passed along to add call of the container. Can be used to adjust layout parameters. May also have other uses.
width	a pre-specified width (in pixels) for the widget
height	a pre-specified height (in pixels) for the widget
ext.args	A list of extra arguments to pass to the ExtJS constructor

Note

The slider updates on "changecomplete", not the more common "change". The "change" signal happens too often for the transferral of values to work reliably. the database can process so these should be used sparingly.
