The Key Descriptor
8
The appearance of each key in a keyboard is determined by its key descriptor. The
key descriptor is a 30-bit value that determines the key size, framing, and other
characteristics. The descriptor is specified by combining any of the constants
shown in Table 8-8.
Table 8-8
Key descriptor constants
keySpacer
Nothing is drawn in this space; it is a spacer, not a key.
keyAutoHilite
Highlight this key when it is pressed.
keyInsetUnit
Inset this key's frame a certain number of pixels within its
space. Multiply this constant by the number of pixels you
want to inset, from 0­7 (for example,
keyInsetUnit*3
).
