Slider

Slider[x]
represents a slider with setting x in the range 0 to 1.
Slider[Dynamic[x]]
takes the setting to be the dynamically updated current value of x, with the value of x being reset if the slider is moved.
Slider[x, {xmin, xmax}]
represents a slider with range xmin to xmax.
Slider[x, {xmin, xmax, dx}]
represents a slider that jumps in steps dx.
Slider[x, {{e1, e2, ...}}]
represents a slider in which equally spaced intervals correspond to successive settings ei.
Slider[x, {{{e1, w1}, {e2, w2}, ...}}]
uses intervals of relative widths wi for the ei.
  • Slider[...] displays in a notebook as a horizontal slider that can be manipulated interactively.
  • Slider[n, {nmin, nmax, dn}] jumps to integer positions if nmin and dn are integers.  »
  • Slider[x, {xmin, xmax, dx}] in general jumps to positions given by Range[xmin, xmax, dx].  »
  • Slider[x] represents a slider running from left to right.
  • Slider[x, {xmax, xmin}] with xmax > xmin represents a slider running from right to left.  »
  • If the value of the slider is outside the range given, it will be displayed at one of the ends.
  • Slider[x, {0, 1, dx}] displays at position x, even if this is not a multiple of dx.
  • In Slider[x, {{e1, e2, ...}}], the ei can be any expressions, not just numbers.  »
  • The following options can be given:
AppearanceAutomaticthe overall appearance of the slider
AutoActionFalsewhether to move the slider automatically when the mouse is over it
BaselinePositionAutomaticalignment relative to surrounding text
BaseStyle{}base style specifications for the slider
ContinuousActionTruewhether to update continuously when the slider is moved
EnabledAutomaticwhether the slider is enabled, or grayed out
Exclusions{}specific values to be excluded
ImageMargins0margins around the image of the displayed slider
ImageSizeAutomaticthe overall image size of the displayed slider
  • Appearance->"Labeled" displays the current value of the slider as an editable label.
  • The settings for BaseStyle are appended to the default style typically given by the "Slider" style in the current stylesheet.

Scope   (5)
Use the range -1 to 1, increasing when going from left to right:
A slider with range 1 to -1, increasing when going from right to left:
Use only integer variable values:
Use rational steps:
Use slider increments of Pi:
Use a symbolic range:
Use a list of possible values:
Change the relative width corresponding to each possible value:
Options   (20)
Different sizes:
Add a label:
Special arrow appearances:
Use dynamic appearance, based on whether Round[x] is 0 or 1:
By default no slider values change until you click in the slider area:
By setting AutoAction, the slider values change as the mouse moves over the slider area:
Change the background colors:
Change the background color dynamically:
Align with the surrounding text:
Dynamically change the baseline position:
By default, variables are continuously updated:
Setting ContinuousAction to False makes variables update only when the slider is released:
By default Slider is enabled:
By setting Enabled->False, the slider is disabled but visible in its current state:
Exclude values from the range:
By setting ImageMargins you make the slider area larger:
Use preset values:
Or use any values:
By setting the second element you can also control the height reserved by the slider:
A fully custom image size:
