- // GTK uses a GtkIMContext object for the following two purposes: |
- // 1. Composing Latin characters (A.1.2), and; |
- // 2. Composing CJK characters with an IME (A.1.3). |
- // Many JavaScript pages assume composed Latin characters are dispatched to |
- // their onkeypress() handlers but not dispatched CJK characters composed |
- // with an IME. To emulate this behavior, we should monitor the status of |
- // this GtkIMContext object and prevent sending Char events when a |
- // GtkIMContext object sends a "commit" signal with the CJK characters |
- // composed by an IME. |

- // flag. |
- // If this flag is true or there are more than one characters in the result, |
- // then the result text will be committed to WebKit as a confirmed |
- // composition. Otherwise, it'll be forwarded as a key event. |
- // |
- // The GtkIMContext object sends a "preedit_start" before it starts composing |
- // a text and a "preedit_end" signal after it finishes composing it. |
- // "preedit_start" signal is monitored to turn it on. |
- // We don't monitor "preedit_end" signal to turn it off, because an input |
- // method may fire "preedit_end" signal before "commit" signal. |
- // A buggy input method may not fire "preedit_start" and/or "preedit_end" |
