The EM_FINDWORDBREAK message finds the next word break before or after the specified character position, or retrieves information about the character at that position.
EM_FINDWORDBREAK wParam = (WPARAM) (UINT) code; lParam = (LPARAM) (DWORD) ichStart;
Value |
Meaning |
WB_CLASSIFY |
Returns the character class and word break flags of the character at the specified position. |
WB_ISDELIMITER |
Returns TRUE if the character at the specified position is a delimiter, or FALSE otherwise. |
WB_LEFT |
Finds the nearest character before the specified position that begins a word. |
WB_LEFTBREAK |
Finds the next word end before the specified position. Same as WB_PREVBREAK. |
WB_MOVEWORDLEFT |
Finds the next character that begins a word before the specified position. This value is used during CTRL+LEFT key processing. Same as WB_MOVEWORDPREV. |
WB_MOVEWORDRIGHT |
Finds the next character that begins a word after the specified position. This value is used during CTRL+RIGHT key processing. Same as WB_MOVEWORDNEXT. |
WB_RIGHT |
Finds the next character that begins a word after the specified position. |
WB_RIGHTBREAK |
Finds the next end-of-word delimiter after the specified position. Same as WB_NEXTBREAK. |
Returns the character index of the word break, unless the code parameter is the WB_CLASSIFY or WB_ISDELIMITER value. For more information, see the description of the code parameter.
If code is WB_LEFT and WB_RIGHT, the word break procedure finds word breaks only after delimiters. This matches the functionality of an edit control. If code is WB_MOVEWORDLEFT or WB_MOVEWORDRIGHT, the word break procedure also compares character classes and word break flags.
For information about character classes and word break flags, see Word and Line Breaks.
