SelBgColor Attribute
Data Type: integer
4GL Access: RW
If the SelBgColor attribute is set (non-zero) and the node is the selected node, then SelBgColor determines the background color of the bounding rectangle of the node.
The default value is 0, which means it takes the value of SelBgColor of the Treeview if it is set, or the default background color (CC_WHITE) if neither is set.
