/*

Header for other program to interact with GoldenDict
|
|
|
|
When GD needs to retrieve word under mouse cursor it can ask for this a target program
|
|
by sending a message.
|
|
|
|
GD_MESSAGE_NAME - name of the this message
|
|
Message number must be retrieved through RegisterWindowMessage function
|
|
|
|
Message parameters:
|
|
WPARAM - 0, not used
|
|
LPARAM - pointer to GDDataStruct structure
|
|
|
|
GDDataStruct fields:
|
|
dwSize - Structure size
|
|
hWnd - Window with requested word
|
|
Pt - Request coordinates (in screen coordinates, device units)
|
|
dwMaxLength - Maximum word length to transfer (buffer size in unicode symbols)
|
|
cwData - Buffer for requested word in UNICODE
|
|
|
|
If program process this message it must fill cwData and return TRUE
|
|
Otherwise GD will work by old technique
