API: slider YAHOO.widget.SliderThumb (YUI Library)

Class YAHOO.widget.SliderThumb - extends YAHOO.util.DD

A drag and drop implementation to be used as the thumb of a slider.

Constructor

YAHOO.widget.SliderThumb

Parameters:: id <String> the id of the slider html element; sGroup <String> the group of related DragDrop items; iLeft <int> the number of pixels the element can move left; iRight <int> the number of pixels the element can move right; iUp <int> the number of pixels the element can move up; iDown <int> the number of pixels the element can move down; iTickSize <int> optional parameter for specifying that the element should move a certain number pixels at a time.

Properties

_graduated `- private boolean`

The slider is _graduated if there is a tick interval defined

_isHoriz `- private boolean`

Flag used to figure out if this is a horizontal or vertical slider

_prevVal `- private int`

Cache the last value so we can check for change

isTarget `- private object`

Overrides the isTarget property in YAHOO.util.DragDrop

maintainOffset `- private boolean`

Informs the drag and drop util that the offsets should remain when resetting the constraints. This preserves the slider value when the constraints are reset

parentElId `- string`

The id of the thumbs parent HTML element (the slider background element).

scroll `- private object`

Turns off the autoscroll feature in drag and drop

startOffset `- [int, int]`

The (X and Y) difference between the thumb location and its parent (the slider background) when the control is instantiated.

tickSize `- private int`

The tick size for this slider
