== New embedding expected initialization sequence == | |||
1. Native UI startup (android UI thread view or Gtk/Qt event loop) | |||
2. Create XRE_InitIPCEmbedding | |||
3. Chromium message loop started | |||
a) Child process created and IPDL channel established | |||
4. Create embed view using embedding API | |||
a) TabParent/Child, DOMWindow initialization | |||
b) PLayers protocol created | |||
6. Render data from UI process LayerManager (SW/HW rendering) to Native UI GC. | |||
7. Load content in remote view (HTML, XUL) | |||
=== Communication between UI and content process === | |||
* Load remote content JS (privileged script with full access) and interact using MessageMessenger (send/receive JSON messages) | |||
* Use embed messaging API (observe broadcast messages) | |||
* Build Application specific IPC serialization library, load XPCOM component in child process linked with this IPC library. | |||
