The Delta filter node allows calculating the incremental delta value of the current value vs. the last input value. The Range defines the maximum value count in case of rotary encoders that would provide the same value range per 360°.
The node can be found under Nodes > Filter Nodes > Delta
Choose an input node from the drop-down or enter a numeric value.
Enter maximum value if incremental values are used to calculate correct delta values between the start and end value.
You will need this for example when using encoders from 0 to 1439.
With Widget Designer version 6, all nodes support so called node commands. Node commands access functions (i.e methods) from a node and / or set a parameter (i.e. property).
Enter "node", followed by the according ID and a dot and a list will pop up showing all available commands for the node. For instance, Node1.TintColor.SetRGB(125,0,255), colors the node in purple.
In addition, the node properties with a parameter ID (the small superscript number) can be edited via the command Node1.SetParam(ID,new Value) or WDNodeSetParam(NodeID,ParamID,Value).
The Node generates the following output:
