How to find a class name of control if control type is "type def"?

[SnowForest]

Hi All,
 
LV 8.5.1 + DSC
 
 
My aim is generate list of all control and indicator class names of certain VI. For example there are three indicators: test_1(boolean), test_2 (numeric) and test_3 (own_type.ctl) when I analyze this vi the print should be followed:
 
Boolean
Numeric
own_type.ctl
 
It is easy to find Boolean and Numeric class names by using property node and property "class name". How I can find recognize type def "class" and find the name of type defination?

Just like you did with the VI, open up a reference to the cluster. And parse it in the same routine. Ton
