I've googled and searched through the forum but can't find a way to remove the focus boxes on components. Specifically TextEditor and ToggleButtons.
Well 2 seconds after posting I found it for the TextBox, but not ToggleButton.
You could set their colour to transparent in the global LookAndFeel, perhaps?
What are the IDs i need to set?
It'll be different for different types of component and will depend on what the LookAndFeel does, but it's IDs like like TextEditor::focusedOutlineColourId
