UI_get_slider_value
![[Exult]](images/exultsm.png)
int UI_get_slider_value(object item, int field_id)
int item->get_slider_value(int field_id)
Returns the current value of a slider widget within a dynamic gump.
Parameters
| Parameter / value | Description |
|---|---|
item |
The object whose dynamic gump contains the slider widget. |
field_id |
The numeric identifier of the slider widget to read. |
Return
The current slider value, or 0 on failure (e.g. if the gump is not found or the field does not exist).
Exult first looks for an open gump belonging to item, then tries its immediate owner's gump. It uses the first slider widget whose field ID matches; an invalid item, missing gump, or missing slider returns 0.
