359 This function copies the results of the input method composition to
|
|
|
360 composed_input_buf. Then for each character, a custom event of type
|
|
|
361 wc_atom is sent with the character as its data.
|
|
|
362
|
|
|
363 It is probably more efficient to copy the composition results to some
|
|
|
364 allocated memory and send a single event pointing to that memory.
|
|
|
365 That would cut down on the event processing as well as allow quick
|
|
|
366 insertion into the buffer of the whole string. It might require some
|
|
|
367 care, though, to avoid fragmenting memory through the allocation and
|
|
|
368 freeing of many small chunks. Maybe the existing system for
|
|
|
369 (single-byte) string allocation can be used, multiplying the length by
|
|
|
370 sizeof (wchar_t) to get the right size.
