Slider Widget

Last updated

A slider that writes a number to a tag when you let go of it.

Settings

Setting	Description	Default

Maximum	Right end	100
Step	Increment. 0 or blank means 1	1
Color	Filled part of the track	#3b82f6 (blue)
Show Value	Minimum, current value and maximum under the slider	on

Binding

Bind value to the same tag, so the slider shows the current value when nobody is dragging it.

Behavior

• The value is written once, when the mouse button or finger is released — not while dragging.
• With the keyboard (arrow, Page Up/Down, Home and End keys), the value is written once when you release the key, so holding an arrow down writes only the final value. Moving focus away from the slider also writes a value that has not been written yet.
• While dragging, the slider shows your position; after release it follows the tag again.
• It writes the local or device tag you pick; failures show a Write failed notification.
