What You Provide
The following is a description of some of the more common embedder-provided interfaces used in embedding Gecko. It is by no means an exhaustive list of the available interfaces.
nsIWebBrowserChrome
The nsIWebBrowserChrome interface corresponds to the top-level, outermost window containing an embedded Gecko web browser. You associate it with the WebBrowser through the nsIWebBrowser interface. It provides control over window setup and whether or not the window is modal. It must be implemented.
nsIEmbeddingSiteWindow
The nsIEmbeddingSiteWindow interface provides Gecko with the means to call up to the host to resize the window, hide or show it and set/get its title. It must be implemented.
nsIWebProgressListener
The nsIWebProgressListener interface provides information on the progress of loading documents. It is added to the WebBrowser through the nsIWebBrowser interface. It must be implemented. As of this writing (8/19/02), it is not frozen.
nsISHistoryListener
The nsISHistoryListener interface is implemented by embedders who wish to receive notifications about activities in session history. A history listener is notified when pages are added, removed and loaded from session history. It is associated with Gecko through the nsIWebBrowser interface. Implementation is optional.
nsIContextMenuListener
The nsIContextMenuListener interface is implemented by embedders who wish to receive notifications for context menu events, i.e. generated by a user right-mouse clicking on a link. It should be implemented on the web browser chrome object associated with the window for which notifications are required. When a context menu event occurs, the browser will call this interface if present. Implementation is optional.
nsIPromptService
The nsIPromptServices interface allows the embedder to override Mozilla's standard prompts: alerts, dialog boxes, and check boxes and so forth. The class that implements these embedder specific prompts must be registered with the Component Manager using the same CID and contract ID that the Mozilla standard prompt service normally uses. Implementation is optional. As of this writing (8/19/02), this interface is not frozen.
