| // Background of this piece of complicated code: |
| // The omnibox supports several special behaviors which may be triggered by |
| // certain key events: |
| // Tab to search - triggered by Tab key |
| // Accept input - triggered by Enter key |
| // Revert input - triggered by Escape key |
| // |
| // Because we use a GtkTextView object |text_view_| for text input, we need |
| // send all key events to |text_view_| before handling them, to make sure |
| // IME works without any problem. So here, we intercept "key-press-event" |
| // signal of |text_view_| object and call its default handler to handle the |
| // key event first. |
| // |
| // Then if the key event is one of Tab, Enter and Escape, we need to trigger |
| // the corresponding special behavior if IME did not handle it. |
| // For Escape key, if the default signal handler returns FALSE, then we know |
| // it's not handled by IME. |
| // |
| // For Tab key, as "accepts-tab" property of |text_view_| is set to FALSE, |
| // if IME did not handle it then "move-focus" signal will be emitted by the |
| // default signal handler of |text_view_|. So we can intercept "move-focus" |
| // signal of |text_view_| to know if a Tab key press event was handled by IME, |
| // and trigger Tab to search or result traversal behavior when necessary in |
| // the signal handler. |
| // |
| // But for Enter key, if IME did not handle the key event, the default signal |
| // handler will delete current selection range and insert '\n' and always |
| // return TRUE. We need to prevent |text_view_| from performing this default |
| // action if IME did not handle the key event, because we don't want the |
| // content of omnibox to be changed before triggering our special behavior. |
| // Otherwise our special behavior would not be performed correctly. |
| // |
| // But there is no way for us to prevent GtkTextView from handling the key |
| // event and performing built-in operation. So in order to achieve our goal, |
| // "insert-text" signal of |text_buffer_| object is intercepted, and |
| // following actions are done in the signal handler: |
| // - If there is only one character in inserted text, and it's '\n' or '\r', |
| // then set |enter_was_inserted_| to true. |
| // - Filter out all new line and tab characters. |
| // |
| // So if |enter_was_inserted_| is true after calling |text_view_|'s default |
| // signal handler against an Enter key press event, then we know that the |
| // Enter key press event was handled by GtkTextView rather than IME, and can |
| // perform the special behavior for Enter key safely. |
| // |
| // Now the last thing is to prevent the content of omnibox from being changed |
| // by GtkTextView when Enter key is pressed. As OnBeforePossibleChange() and |
| // OnAfterPossibleChange() will be called by GtkTextView before and after |
| // changing the content, and the content is already saved in |
| // OnBeforePossibleChange(), so if the Enter key press event was not handled |
| // by IME, it's easy to restore the content in OnAfterPossibleChange(), as if |
