I was wondering if it is possible to retrieve the width of the inspector window somehow. I am trying to create an custom inspector and I want to set the label and field widtn of an popup relative to the width of the window. so 50%, 50% with EditorGUIUtility.LookLikeControls I can only set the widths to a static value , not procentual relative to the entire width. When I would have the Inspector Window's width, I could calculate those 50% width values myself. Anyone?
