WM_IME_CHAR message
Sent to an application when the IME gets a character of the conversion result. A window receives this message through its WindowProc function.
LRESULT CALLBACK WindowProc(
HWND hwnd,
WM_IME_CHAR,
WPARAM wParam,
LPARAM lParam
);
-
hwnd
-
A handle to window.
-
wParam
-
DBCS: A single-byte or double-byte character value. For a double-byte character, (BYTE)(wParam >> 8) contains the lead byte. Note that the parentheses are necessary because the cast operator has higher precedence than the shift operator.
Unicode: A Unicode character value.
-
lParam
-
The repeat count, scan code, extended key flag, context code, previous key state flag, and transition state flag, with values as defined below.
Bit Meaning 0-15 Repeat count. Since the first byte and second byte are continuous, this is always 1. 16-23 Scan code for a complete Asian character. 24 Extended key. 25-28 Not used. 29 Context code. 30 Previous key state. 31 Transition state.
Unlike the WM_CHAR message for a non-Unicode window, this message can include double-byte and single-byte character values. For a Unicode window, this message is the same as WM_CHAR.
For a non-Unicode window, if the WM_IME_CHAR message includes a double-byte character and the application passes this message to DefWindowProc, the IME converts this message into two WM_CHAR messages, each containing one byte of the double-byte character.
