| 69 // RenderViewHost | |
| 70 // | |
| 71 // A RenderViewHost is responsible for creating and talking to a RenderView | |
| 72 // object in a child process. It exposes a high level API to users, for things | |
| 73 // like loading pages, adjusting the display and other browser functionality, | |
| 74 // which it translates into IPC messages sent over the IPC channel with the | |
| 75 // RenderView. It responds to all IPC messages sent by that RenderView and | |
| 76 // cracks them, calling a delegate object back with higher level types where | |
| 77 // possible. | |
| 78 // | |
| 79 // The intent of this class is to provide a view-agnostic communication | |
| 80 // conduit with a renderer. This is so we can build HTML views not only as | |
| 81 // TabContents (see TabContents for an example) but also as views, etc. | |
| 82 // | |
| 83 // The exact API of this object needs to be more thoroughly designed. Right | |
| 84 // now it mimics what TabContents exposed, which is a fairly large API and may | |
| 85 // contain things that are not relevant to a common subset of views. See also | |
| 86 // the comment in render_view_host_delegate.h about the size and scope of the | |
| 87 // delegate API. | |
| 88 // | |
| 89 // Right now, the concept of page navigation (both top level and frame) exists | |
| 90 // in the TabContents still, so if you instantiate one of these elsewhere, you | |
| 91 // will not be able to traverse pages back and forward. We need to determine | |
| 92 // if we want to bring that and other functionality down into this object so | |
| 93 // it can be shared by others. | |
