## Description

Each EphyTab contains an EphyEmbed. An EphyEmbed is an interface; right now it is only implemented by MozillaEmbed, but whenever possible, EphyEmbed's functions should be used instead of their MozillaEmbed equivalents.

EphyEmbed's most important functions can be divided into sets:

- Functions which affect navigation
- Functions which return information about the displayed web page
- Functions which manipulate the session history

The first two sets of functions are self-explanitory.

The session history functions are used to traverse the embedded browser's history. Each EphyEmbed remembers a history of the web pages it has visited. There can be a maximum limit, however; for MozillaEmbed, this limit is determined by Mozilla's browser.sessionhistory.max_entries preference. Because of this limit, `ephy_embed_shistory_n_items()` will not necessarily return the number of web pages visited in the embed's lifetime; likewise, `ephy_embed_shistory_go_nth()` will not always return to the user's home page when called with a 0 argument.

### enum EmbedState

    typedef enum
    {
    	EMBED_STATE_UNKNOWN		= 0,
    	EMBED_STATE_START		= 1 << 0,
    	EMBED_STATE_REDIRECTING		= 1 << 1,
    	EMBED_STATE_TRANSFERRING	= 1 << 2,
    	EMBED_STATE_NEGOTIATING		= 1 << 3,
    	EMBED_STATE_STOP		= 1 << 4,

    	EMBED_STATE_IS_REQUEST		= 1 << 5,
    	EMBED_STATE_IS_DOCUMENT		= 1 << 6,
    	EMBED_STATE_IS_NETWORK		= 1 << 7,
    	EMBED_STATE_IS_WINDOW		= 1 << 8
    } EmbedState;

Represents the state of an EphyEmbed with regards to networking negotiations.

### enum EphyEmbedChrome

    typedef enum
    {
    	EPHY_EMBED_CHROME_MENUBAR	= 1 << 0,
    	EPHY_EMBED_CHROME_TOOLBAR	= 1 << 1,
    	EPHY_EMBED_CHROME_STATUSBAR	= 1 << 2,
    	EPHY_EMBED_CHROME_BOOKMARKSBAR	= 1 << 3
    } EphyEmbedChrome;

Determines which aspects of the user interface should be displayed. Most of the time, an EphyEmbed's chrome will simply be `EPHY_EMBED_CHROME_DEFAULT`. However, windows opened with JavaScript often use a nonstandard chrome.

`EPHY_EMBED_CHROME_MENUBAR` | `TRUE` for the EphyEmbed's containing EphyWindow to display its menubar.
`EPHY_EMBED_CHROME_TOOLBAR` | `TRUE` for the EphyEmbed's containing EphyWindow to display its toolbars.
`EPHY_EMBED_CHROME_STATUSBAR` | `TRUE` for the EphyEmbed's containing EphyWindow to display its statusbar.
`EPHY_EMBED_CHROME_BOOKMARKSBAR` |

### enum EmbedPrintPreviewNavType

    typedef enum
    {
    	PRINTPREVIEW_GOTO_PAGENUM	= 0,
    	PRINTPREVIEW_PREV_PAGE		= 1,
    	PRINTPREVIEW_NEXT_PAGE		= 2,
    	PRINTPREVIEW_HOME		= 3,
    	PRINTPREVIEW_END		= 4
    } EmbedPrintPreviewNavType;

Specifies the action to perform in `ephy_embed_print_preview_navigate()`.

### enum EmbedSecurityLevel

    typedef enum
    {
    	STATE_IS_UNKNOWN,
    	STATE_IS_INSECURE,
    	STATE_IS_BROKEN,
    	STATE_IS_SECURE_MED,
    	STATE_IS_SECURE_LOW,
    	STATE_IS_SECURE_HIGH
    } EmbedSecurityLevel;

Represents the security status of an EphyEmbed. For example, a page with an invalid SSL certificate will have an EmbedSecurityLevel of `STATE_IS_BROKEN`.

### ephy_embed_load_url ()

    void        ephy_embed_load_url             (EphyEmbed *embed,
                                                 const char *url);

Loads a new web page in `embed`.

`embed` : | an EphyEmbed
`url` : | a URL

### ephy_embed_stop_load ()

    void        ephy_embed_stop_load            (EphyEmbed *embed);

If `embed` is loading, stops it from continuing.

`embed` : | an EphyEmbed

### ephy_embed_reload ()

    void        ephy_embed_reload               (EphyEmbed *embed,
                                                 gboolean force);

Reloads the web page being displayed in `embed`.

If `force` is `TRUE`, cache and proxy will be bypassed when reloading the page.

`embed` : | an EphyEmbed
`force` : | `TRUE` to bypass cache

### ephy_embed_get_title ()

    char*       ephy_embed_get_title            (EphyEmbed *embed);

`embed` : | an EphyEmbed
Returns : | the title of the web page displayed in `embed`

### ephy_embed_get_location ()

    char*       ephy_embed_get_location         (EphyEmbed *embed,
                                                 gboolean toplevel);

Returns the URL of the web page displayed in `embed`.

If the web page contains frames, `toplevel` will determine which location to retrieve. If `toplevel` is `TRUE`, the return value will be the location of the frameset document. If `toplevel` is `FALSE`, the return value will be the location of the currently-focused frame.

`embed` : | an EphyEmbed
`toplevel` : | `FALSE` to return the location of the focused frame only
Returns : | the URL of the web page displayed in `embed`

### ephy_embed_get_link_message ()

    char*       ephy_embed_get_link_message     (EphyEmbed *embed);
