Details and Options

• Slider[…] displays in a notebook as a horizontal slider that can be manipulated interactively.
• Slider[Dynamic[x]] will reset the value of x when the slider is moved; Slider[x] will not.
• Slider[n,{n_min,n_max,dn}] jumps to integer positions if n_min and dn are integers. »
• Slider[x,{x_min,x_max,dx}] in general jumps to positions given by Range[x_min,x_max,dx]. »
• Slider[x] represents a slider running from left to right.
• Slider[x,{x_max,x_min}] with x_max > x_min 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 e_i can be any expressions, not just numbers. »
• The following options can be given:
• Appearance Automaticthe overall appearance of the slider AutoAction Falsewhether to move the slider automatically when the mouse is over it BaselinePosition Automaticalignment relative to surrounding text BaseStyle{}base style specifications for the slider ContinuousAction Truewhether to update continuously when the slider is moved Enabled Automaticwhether the slider is enabled or grayed out Exclusions {}specific values to be excluded ImageMargins 0margins around the image of the displayed slider ImageSize Automaticthe overall image size of the displayed slider

• Slider[] is equivalent to Slider[0.5].
• The resulting slider can be finely manipulated by holding down the key (or on Macintosh) while dragging the mouse. This causes the slider to move at 1/20 the rate of the mouse. The slider can be even more finely manipulated by also holding the and/or keys.
