Dynamic max for ui dashboard slider node

Rtholl · 22 October 2019 14:56

Hey guys,

Is there a way to feed the ui dashboard slider node an integer for the maximum value? My idea is to take the length of an array and feed this as the maximum of the slider node. Something like:

"msg.ui_slider.max = array.length;"

and this would dynamically control the slider node's maximum value.

## UI Widget configuration via msg.ui_control

The following configuration properties of ui widget nodes can be set by using a `msg.ui_control` property on a msg.
Multiple properties of the node can be set at the same time. For example you can use a change
node to set msg.ui_control to JSON `{ "min":10, "max":50 }`

**Note**: It is still recommended that nodes are configured via the editor in order to preset the default values.
