| // EventHandler::keyEvent() -> |
| // ... |

| // [WebHTMLView _interceptEditingKeyEvent] -> |
| // [NSResponder interpretKeyEvents] -> |
| // [WebHTMLView insertText] -> |
| // Editor::insertText() |
| // |
| // Unfortunately, it is hard for Chromium to use this implementation because |
| // it causes key-typing jank. |
| // RenderWidgetHostViewMac is running in a browser process. On the other |
| // hand, Editor and EventHandler are running in a renderer process. |
| // So, if we used this implementation, a NSKeyDown event is dispatched to |
| // the following functions of Chromium. |
| // |
| // [RenderWidgetHostViewMac keyEvent] (browser) -> |
| // |Sync IPC (KeyDown)| (*1) -> |
| // EventHandler::keyEvent() (renderer) -> |
| // ... |
| // EditorClientImpl::handleKeyboardEvent() (renderer) -> |
| // |Sync IPC| (*2) -> |
| // [RenderWidgetHostViewMac _interceptEditingKeyEvent] (browser) -> |
| // [self interpretKeyEvents] -> |
| // [RenderWidgetHostViewMac insertText] (browser) -> |
| // |Async IPC| -> |
| // Editor::insertText() (renderer) |
| // |
| // (*1) we need to wait until this call finishes since WebHTMLView uses the |
| // result of EventHandler::keyEvent(). |
| // (*2) we need to wait until this call finishes since WebEditorClient uses |
| // the result of [WebHTMLView _interceptEditingKeyEvent]. |
| // |
| // This needs many sync IPC messages sent between a browser and a renderer for |
| // each key event, which would probably result in key-typing jank. |
| // To avoid this problem, this implementation processes key events (and input |
| // method events) totally in a browser process and sends asynchronous input |
| // events, almost same as KeyboardEvents (and TextEvents) of DOM Level 3, to a |
| // renderer process. |
| // |
| // [RenderWidgetHostViewMac keyEvent] (browser) -> |
| // |Async IPC (RawKeyDown)| -> |
| // [self interpretKeyEvents] -> |
| // [RenderWidgetHostViewMac insertText] (browser) -> |
| // |Async IPC (Char)| -> |
| // Editor::insertText() (renderer) |
