}

Implement this structure to handle events related to browser display state. The functions of this structure will be called on the UI thread.

NOTE: This struct is allocated client-side.

Fields

base: cef_base_ref_counted_t

Base structure.

on_address_change: Option<unsafe extern "C" fn(self_: *mut _cef_display_handler_t, browser: *mut _cef_browser_t, frame: *mut _cef_frame_t, url: *const cef_string_t)>

Called when a frame’s address has changed.

on_title_change: Option<unsafe extern "C" fn(self_: *mut _cef_display_handler_t, browser: *mut _cef_browser_t, title: *const cef_string_t)>

Called when the page title changes.

on_favicon_urlchange: Option<unsafe extern "C" fn(self_: *mut _cef_display_handler_t, browser: *mut _cef_browser_t, icon_urls: cef_string_list_t)>

Called when the page icon changes.

on_fullscreen_mode_change: Option<unsafe extern "C" fn(self_: *mut _cef_display_handler_t, browser: *mut _cef_browser_t, fullscreen: c_int)>

Called when web content in the page has toggled fullscreen mode. If |fullscreen| is true (1) the content will automatically be sized to fill the browser content area. If |fullscreen| is false (0) the content will automatically return to its original size and position. With Alloy style the client is responsible for triggering the fullscreen transition (for example, by calling cef_window_t::SetFullscreen when using Views). With Chrome style the fullscreen transition will be triggered automatically. The cef_window_delegate_t::OnWindowFullscreenTransition function will be called during the fullscreen transition for notification purposes.

on_tooltip: Option<unsafe extern "C" fn(self_: *mut _cef_display_handler_t, browser: *mut _cef_browser_t, text: *mut cef_string_t) -> c_int>

Called when the browser is about to display a tooltip. |text| contains the text that will be displayed in the tooltip. To handle the display of the tooltip yourself return true (1). Otherwise, you can optionally modify |text| and then return false (0) to allow the browser to display the tooltip. When window rendering is disabled the application is responsible for drawing tooltips and the return value is ignored.

on_status_message: Option<unsafe extern "C" fn(self_: *mut _cef_display_handler_t, browser: *mut _cef_browser_t, value: *const cef_string_t)>

Called when the browser receives a status message. |value| contains the text that will be displayed in the status message.

on_console_message: Option<unsafe extern "C" fn(self_: *mut _cef_display_handler_t, browser: *mut _cef_browser_t, level: cef_log_severity_t, message: *const cef_string_t, source: *const cef_string_t, line: c_int) -> c_int>

Called to display a console message. Return true (1) to stop the message from being output to the console.

on_auto_resize: Option<unsafe extern "C" fn(self_: *mut _cef_display_handler_t, browser: *mut _cef_browser_t, new_size: *const cef_size_t) -> c_int>

Called when auto-resize is enabled via cef_browser_host_t::SetAutoResizeEnabled and the contents have auto- resized. |new_size| will be the desired size in DIP coordinates. Return true (1) if the resize was handled or false (0) for default handling.

on_loading_progress_change: Option<unsafe extern "C" fn(self_: *mut _cef_display_handler_t, browser: *mut _cef_browser_t, progress: f64)>

Called when the overall page loading progress has changed. |progress| ranges from 0.0 to 1.0.

on_cursor_change: Option<unsafe extern "C" fn(self_: *mut _cef_display_handler_t, browser: *mut _cef_browser_t, cursor: cef_cursor_handle_t, type_: cef_cursor_type_t, custom_cursor_info: *const cef_cursor_info_t) -> c_int>

Called when the browser’s cursor has changed. If |type| is CT_CUSTOM then |custom_cursor_info| will be populated with the custom cursor information. Return true (1) if the cursor change was handled or false (0) for default handling.

on_media_access_change: Option<unsafe extern "C" fn(self_: *mut _cef_display_handler_t, browser: *mut _cef_browser_t, has_video_access: c_int, has_audio_access: c_int)>

Called when the browser’s access to an audio and/or video source has changed.

on_contents_bounds_change: Option<unsafe extern "C" fn(self_: *mut _cef_display_handler_t, browser: *mut _cef_browser_t, new_bounds: *const cef_rect_t) -> c_int>

Called when JavaScript is requesting new bounds via window.moveTo/By() or window.resizeTo/By(). |new_bounds| are in DIP screen coordinates.

With Views-hosted browsers |new_bounds| are the desired bounds for the containing cef_window_t and may be passed directly to cef_window_t::SetBounds. With external (client-provided) parent on macOS and Windows |new_bounds| are the desired frame bounds for the containing root window. With other non-Views browsers |new_bounds| are the desired bounds for the browser content only unless the client implements either cef_display_handler_t::GetRootWindowScreenRect for windowed browsers or cef_render_handler_t::GetWindowScreenRect for windowless browsers. Clients may expand browser content bounds to window bounds using OS-specific or cef_display_t functions.

Return true (1) if this function was handled or false (0) for default handling. Default move/resize behavior is only provided with Views-hosted Chrome style browsers.

get_root_window_screen_rect: Option<unsafe extern "C" fn(self_: *mut _cef_display_handler_t, browser: *mut _cef_browser_t, rect: *mut cef_rect_t) -> c_int>

Called to retrieve the external (client-provided) root window rectangle in screen DIP coordinates. Only called for windowed browsers on Windows and Linux. Return true (1) if the rectangle was provided. Return false (0) to use the root window bounds on Windows or the browser content bounds on Linux. For additional usage details see cef_browser_host_t::NotifyScreenInfoChanged.
