borderWidth
The width of the receiver’s border when the receiver is a custom box with a simple line border.
Declaration
var borderWidth: CGFloat { get set }Discussion
The receiver’s border width. It must be a custom box—that is, it has a type of NSBox.BoxType.custom—and it must have a border style of NSBorderType.lineBorder.
Special Considerations
Functional only when the receiver’s box type (boxType) is NSBoxCustom and its border type (borderType) is NSLineBorder.
