## Functions

### EWebViewElementClickedFunc ()

    void
    (*EWebViewElementClickedFunc) (EWebView *web_view,
                                   const gchar *iframe_id,
                                   const gchar *element_id,
                                   const gchar *element_class,
                                   const gchar *element_value,
                                   const GtkAllocation *element_position,
                                   gpointer user_data);

The callback is called whenever an element of class `element_class` is clicked. The `element_value` is a content of the 'value' attribute of the clicked element. The `element_position` is the place of the element within the web page, already accounting scrollbar positions.

See: e_web_view_register_element_clicked, e_web_view_unregister_element_clicked

#### Parameters

web_view | an EWebView |
iframe_id | an iframe ID in which the click happened; empty string for the main frame |
element_id | an element ID |
element_class | an element class, as set on the element which had been clicked |
element_value | a 'value' attribute content of the clicked element |
element_position | a GtkAllocation with the position of the clicked element |
user_data | user data as provided in the `e_web_view_register_element_clicked()` call |

    e_web_view_suggest_filename (EWebView *web_view,

Attempts to derive a suggested filename from the `uri` for use in a "Save As" dialog.

By default the suggested filename is the last path segment of the `uri` (unless `uri` looks like a query), but subclasses can use other mechanisms for custom URI schemes. For example, "cid:" URIs in an email message may refer to a MIME part with a suggested filename in its Content-Disposition header.

The returned string should be freed with `g_free()` when finished with it, but callers should also be prepared for the function to return `NULL` if a filename cannot be determined.

#### Parameters

web_view | an EWebView |
uri | a URI string |

#### Returns

a suggested filename, or `NULL`

### e_web_view_new_activity ()

    EActivity *
    e_web_view_new_activity (EWebView *web_view);

Returns a new EActivity for an EWebView-related asynchronous operation, and emits the “new-activity” signal. By default the EActivity comes loaded with a GCancellable and sets the `web_view` itself as the “alert-sink” (which means alerts are displayed directly in the content area). The signal emission allows the EActivity to be further customized and/or tracked by the application.

#### Parameters

web_view | an EWebView |

#### Returns

an EActivity

### e_web_view_status_message ()

### e_web_view_cursor_image_copy ()

    void
    e_web_view_cursor_image_copy (EWebView *web_view);

Asynchronously copies the image under the cursor to the clipboard.

This function triggers an “new-activity” signal emission so the asynchronous operation can be tracked and/or cancelled.

#### Parameters

web_view | an EWebView |

### e_web_view_cursor_image_save ()

    void
    e_web_view_cursor_image_save (EWebView *web_view);

Prompts the user to choose a destination file and then asynchronously saves the image under the cursor to the destination file.

This function triggers an “new-activity” signal emission so the asynchronous operation can be tracked and/or cancelled.

#### Parameters

web_view | an EWebView |

### e_web_view_request ()

    void
    e_web_view_request (EWebView *web_view,
                        const gchar *uri,
                        GCancellable *cancellable,
                        GAsyncReadyCallback callback,
                        gpointer user_data);

Asynchronously requests data at `uri` as displaed in the `web_view` .

When the operation is finished, `callback` will be called. You can then call `e_web_view_request_finish()` to get the result of the operation.

#### Parameters

web_view | an EWebView |
uri | the URI to load |
cancellable | optional GCancellable object, or `NULL` |
callback | a GAsyncReadyCallback to call when the request is satisfied |
user_data | data to pass to the callback function |

### e_web_view_request_finish ()

    GInputStream *
    e_web_view_request_finish (EWebView *web_view,
                               GAsyncResult *result,
                               GError **error);

Finishes the operation started with `e_web_view_request()`.

Unreference the returned GInputStream with `g_object_unref()` when finished with it. If an error occurred, the function will set `error` and return `NULL`.

#### Parameters

web_view | an EWebView |
result | a GAsyncResult |
error | return location for a GError, or `NULL` |

#### Returns

a GInputStream, or `NULL`

### e_web_view_install_request_handler ()

    void
    e_web_view_install_request_handler (EWebView *web_view,
                                        GType handler_type);

### e_web_view_get_citation_color_for_level ()

    const gchar *
    e_web_view_get_citation_color_for_level
                                   (gint level);

### e_web_view_set_iframe_src ()

    void
    e_web_view_set_iframe_src (EWebView *web_view,
                               const gchar *iframe_id,
                               const gchar *new_src);

Change IFrame source for the given `document_uri` IFrame to the `new_iframe_src` .

#### Parameters

web_view | an EWebView |
document_uri | a document URI for whose IFrame change the source |
src_uri | the source to change the IFrame to |

                                         EWebViewElementClickedFunc callback,
                                         gpointer user_data);

Registers a `callback` to be called when any element of the class `element_class` is clicked. If the element contains a 'value' attribute, then it is passed to the `callback` too. These callback are valid until a new content of the `web_view` is loaded, after which all the registered callbacks are forgotten.

#### Parameters

web_view | an EWebView |
element_class | an element class on which to listen for clicking |
callback | an EWebViewElementClickedFunc to call, when the element is clicked |
user_data | user data to pass to `callback` |

### e_web_view_unregister_element_clicked ()

    void
    e_web_view_unregister_element_clicked (EWebView *web_view,
                                           const gchar *element_class,
                                           EWebViewElementClickedFunc callback,
                                           gpointer user_data);

Unregisters the `callback` for the `element_class` with the given `user_data` , which should be previously registered with `e_web_view_register_element_clicked()`. This unregister is usually not needed, because the `web_view` unregisters all callbacks when a new content is loaded.

#### Parameters

web_view | an EWebView |
element_class | an element class on which to listen for clicking |
callback | an EWebViewElementClickedFunc to call, when the element is clicked |
user_data | user data to pass to `callback` |
