PE_MOREDATA

Sent to the window specified by the htrgTarget member of the TARGET structure to indicate that more pen data is available for that window. Submessage of WM_PENEVENT.

Parameters
wParam

PE_MOREDATA.

lParam

Address of an INPPARAMS structure.

Comments
DefWindowProc collects the pen input in response to the PE_PENDOWN, PE_PENUP, and PE_PENMOVE messages and sends the input on a stroke-by-stroke basis to one of the targets in the TARGINFO structure. On a pen-tip transition

that is, from pen-down to pen-up or vice versa

the Windows DefWindowProc function sends a PE_MOREDATA message to the window specified by the htrgTarget member of the TARGET structure identified in the PE_BEGINDATA message.

If it receives a PE_MOREDATA message, DefWindowProc uses AddPointsPendata or AddPenInputHRC, or does nothing, depending on whether the data type in the dwData member of the TARGET structure is a handle to an HPENDATA, an HRC handle for handwriting recognition, or some private data type.
