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/>

Gli stili sono di tipo comune oppure associati a un tema specifico. Se lo stile è comune, può essere utilizzato con qualunque tema. Se è associato a un tema specifico, può essere utilizzato solo se la vostra applicazione ne fa uso.
Questo componente utilizza skin costituiti da più parti. Non impostate le parti degli skin direttamente. Vengono impostate dallo skin del componente.
Per applicare uno skin al componente, implementate uno skin che definisce gli stati seguenti. Benché sia necessario implementare tutti gli stati dello skin, potete lasciare vuoto uno stato di skin. Uno stato di skin vuoto non applica alcuna modifica allo stato predefinito dello skin.
