typedef struct TEStyleRec { Size Offset Description

short nRuns; 2 0 Number of elements in runs

short nStyles; 2 2 Number of elements in handle at styleTab

STHandle styleTab; 4 4 Handle to style table

LHHandle lhTab; 4 8 Handle to line-height table

long teRefCon; 4 12 Available for use by applications

NullSTHandle nullStyle; 4 16 Handle to styles for null selection

StyleRun runs[8001]; n 20 List of offsets and style table indexes

} TEStyleRec; 20+n (n is nRuns * 4)

typedef TEStyleRec **TEStyleHandle;

Notes: In the new style-aware TERec, the fields at offsets 74-77 (the txFont and

txFace and the 1-byte filler) contain a 4-byte TEStyleHandle which leads

to this data structure, also known as the "style record".

Although all TextEdit style-related functions depend on it, a TEStyleHandle

is used in only two functions directly (SetStylHandle and

GetStylHandle). It is the starting point for a complex set of

inter-dependent records.

The amount of data in the line-height table (at lhTab) depends on the value

of TERec.nLines. There is one LHElement for each line in the edit record.

The nullStyle handle eventually leads to an STScrpRec. It defines the font,

face, etc. for text which is inserted via TEKey when the selection range is

an insertion point.

The runs field is variable length, but always contains at least one 4-byte

StyleRun with an index to the first style in the style table lead to by

styleTab (which gets initialized to the TextEdit defaults for font, face, etc.).
