Floating Panels

The 

selectionChanged()

 function first calls the 

dw.getDocumentDOM()

 function to get the 

Document Object Model (DOM) for the user’s document. It then calls the 

getSelectedNode()

 function to see if the selected node for that document is, first, an

 function makes the 

scripteditor
