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).

In addition to the general commands, this nodes provides specific function commands that can replace pressing the buttons or entering values in the Configuration dialog manually. E.g. Node1.CameraExposure(148530,500) sets the exposure of the camera with serial number "148530" to 500µs without opening the dialog.
