The slider can allow a continuous range of values between its minimum and maximum values or it can be restricted to values at specific intervals between the minimum and maximum value. The slider can contain a data tip to show its current value.
The HSlider control has the following default characteristics:
Characteristic | Description |
---|---|
Default size | 100 pixels wide by 11 pixels high |
Minimum size | 100 pixels wide and 100 pixels high |
Maximum size | 10000 pixels wide and 10000 pixels high |
Default skin classes | spark.skins.spark.HSliderSkin
spark.skins.spark.HSliderThumbSkin spark.skins.spark.HSliderTrackSkin |
The <s:HSlider>
tag inherits all of the tag
attributes of its superclass and adds no tag attributes:
<s:HSlider/>
