I am attempting to use "addSelectionBoxElement" to add an edit button to a selected object in my application. After working with it a bit, I've realized that it is a TransformManager method, so it adds that edit button to every single TransformItem associated with my TransformManager. What I am trying to do is only add the edit button to specific TransformItems (for example I have Shapes, TextField, images, etc). Is there any way to only add the edit button for specific objects, or to hide the edit button when certain objects are selected? Thanks for your help.
