Text and Ink Input and Display

Using Text

Apple recommending using the normal, bold, and underline font
styles. The other styles do not necessarily display well on
Newton screens.

For pointSize, use an integer that specifies the point size value.

You can specify a font in one 30-bit integer. A packed integer font specification
uses the lower 10 bits for the font family, the middle 10 bits for the font size, and
the upper 10 bits for the font style. Since only the ROM fonts have predefined font
family number constants, you can only specify ROM fonts in a packed value.

The system provides several constants you can use to specify one of the built-in fonts.
These constants are listed in Table 8-5. The fonts shown in the table can be specified
by the constant (usable at compile time only), by their font frame, or by an integer
value that packs all of the font information into an integer (sometimes this is what
you see at run time if you examine a

viewFont

slot in the NTK Inspector).
