Class Detail
Slider(start,end,data)
Parameters:
{Array_Array_Array} start,end,data
The first two arrays give the start and the end where the slider is drawn on the board. The third array gives the start and the end of the range the slider operates as the first resp. the third component of the array. The second component of the third array gives its start value.


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
// Create a slider with values between 1 and 10, initial position is 5.
var s = board.create('slider', [[1, 2], [3, 2], [1, 5, 10]]);

				
				
// Create a slider taking integer values between 1 and 50. Initial value is 50.
var s = board.create('slider', [[1, 3], [3, 1], [0, 10, 50]], {snapWidth: 1, ticks: { drawLabels: true }});
