Passing strict type def control as refnum to subVI

[Mark_Ireton]

I would like to modify various properties of a strict type def control (cluster) in a subVI.  For example, I might want to change colors or the blinking property and have the change take effect on the top-level VI.  My first thought was to pass a control refnum to the subVI.  When I created the front panel for the subVI, I could not find a way to set the type of the control refnum.  When I right-click and choose "Select VI Server Class" I select Generic>GObject>Control>RefNum>TypedRefNum.  I don't know how to define the specific type def so that I don't get a class conflict.

Is there a better way to do this kind of thing?  If not, then what is the proper way to assign the type def of a control refnum?

Thanks, Mark

Try putting a generic control refnum on your front panel and then dragging a copy of your typedef onto it. viola'!

Or, right click on your targeted object then select Create reference => you copy the refnum in your SubVI and you link it to the invoke or property node.
