STROKEINFO
- 0 2.0
Contains information about a sequence of pen data.
typedef struct {
UINT cPnt;
UINT cbPnts;
UINT wPdk;
DWORD dwTick;
} STROKEINFO;
Members
cPnt
Count of points in the stroke.
cbPnts
Used internally to contain length of compressed data. Applications should
ignore this value.
wPdk
State of the stroke, expressed as a PDK_ value.
dwTick
Time at beginning of the stroke.
dwTick holds the number of milliseconds that have elapsed since the system tick
reference that Windows determines at startup.
Comments
The
STROKEINFO structure serves two main purposes. First, it is returned by the
GetPenHwEventData functions with each piece of new data from the tablet. Second, it is used in
certain pen data functions such as
AddPenInputHRC,
AddPointsPenData, and
GetPenDataStroke as a header for each stroke. In both cases, it contains information about a
sequence of data from the tablet.
For examples and further information about
STROKEINFO and its members, see the section "Recognition Functions" in Chapter 8,
"Writing a Recognizer."
For a list of stroke state bits, refer to the entry for PDK_ values in Chapter
13, "Pen Application Programming Interface Constants."
