I want to create tab preview in tooltip. For this I need to capture tab content before tooltip will be shown to user. For this I use Node.snapshot() method.

I was trying to wrap text for a particular table column in my TableView. I implemented the below code for that. Problem with this code is that it sets the default Text color as Black.
