Setting a Box’s Border Appearance

The appearance of an NSBox is set using a combination of the methods setBoxType: and setBorderType:. By default an NSBox instance is set to use the NSBoxPrimary box type and the NSGrooveBorder border type.

The appearance in Figure 1 is achieved by calling the method setBorderType: and specifying NSNoBorder as the box type.

The appearance in Figure 2 is achieved by calling the method setBorderType: and specifying NSGrooveBorder as the border type, and calling setBoxType: and specifying NSBoxPrimary as the box type.

The appearance in Figure 3 is achieved by calling the method setBorderType: and specifying NSGrooveBorder as the border type, and calling setBoxType: and specifying NSBoxSecondary as the box type.

Note that the border appears inside the box and can reduce the amount of space available to the content rectangle.
