Add an observer for DevTools protocol messages (function results and events). The observer will remain registered until the returned Registration object is destroyed. See the SendDevToolsMessage documentation for additional usage information.
Add the specified |word| to the spelling dictionary.
Base structure.
Returns true (1) if this browser can execute the specified zoom command. This function can only be called on the UI thread.
Request that the browser close. The JavaScript 'onbeforeunload' event will be fired. If |force_close| is false (0) the event handler, if any, will be allowed to prompt the user and the user can optionally cancel the close. If |force_close| is true (1) the prompt will not be displayed and the close will proceed. Results in a call to
Explicitly close the associated DevTools browser, if any.
Download |image_url| and execute |callback| on completion with the images received from the renderer. If |is_favicon| is true (1) then cookies are not sent and not accepted during download. Images with density independent pixel (DIP) sizes larger than |max_image_size| are filtered out from the image results. Versions of the image at different scale factors may be downloaded up to the maximum scale factor supported by the system. If there are no image results <= |max_image_size| then the smallest image is resized to |max_image_size| and is the only result. A |max_image_size| of 0 means unlimited. If |bypass_cache| is true (1) then |image_url| is requested from the server even if it is present in the browser cache.
Call this function when the drag operation started by a
Call this function when the drag operation started by a
Call this function when the user drags the mouse into the web view (before calling DragTargetDragOver/DragTargetLeave/DragTargetDrop). |drag_data| should not contain file contents as this type of data is not allowed to be dragged into the web view. File contents can be removed using
Call this function when the user drags the mouse out of the web view (after calling DragTargetDragEnter). This function is only used when window rendering is disabled.
Call this function each time the mouse is moved across the web view during a drag operation (after calling DragTargetDragEnter and before calling DragTargetDragLeave/DragTargetDrop). This function is only used when window rendering is disabled.
Call this function when the user completes the drag operation by dropping the object onto the web view (after calling DragTargetDragEnter). The object being dropped is |drag_data|, given as an argument to the previous DragTargetDragEnter call. This function is only used when window rendering is disabled.
Execute a function call over the DevTools protocol. This is a more structured version of SendDevToolsMessage. |message_id| is an incremental number that uniquely identifies the message (pass 0 to have the next number assigned automatically based on previous values). |function| is the function name. |params| are the function parameters, which may be NULL. See the DevTools protocol documentation (linked above) for details of supported functions and the expected |params| dictionary contents. This function will return the assigned message ID if called on the UI thread and the message was successfully submitted for validation, otherwise 0. See the SendDevToolsMessage documentation for additional usage information.
Requests the renderer to exit browser fullscreen. In most cases exiting window fullscreen should also exit browser fullscreen. With the Alloy runtime this function should be called in response to a user action such as clicking the green traffic light button on MacOS (cef_window_delegate_t::OnWindowFullscreenTransition callback) or pressing the "ESC" key (cef_keyboard_handler_t::OnPreKeyEvent callback). With the Chrome runtime these standard exit actions are handled internally but new/additional user actions can use this function. Set |will_cause_resize| to true (1) if exiting browser fullscreen will cause a view resize.
Search for |searchText|. |forward| indicates whether to search forward or backward within the page. |matchCase| indicates whether the search should be case-sensitive. |findNext| indicates whether this is the first request or a follow-up. The search will be restarted if |searchText| or |matchCase| change. The search will be stopped if |searchText| is NULL. The cef_find_handler_t instance, if any, returned via
Returns the hosted browser object.
Returns the client for this browser.
Get the default zoom level. This value will be 0.0 by default but can be configured with the Chrome runtime. This function can only be called on the UI thread.
Returns the extension hosted in this browser or NULL if no extension is hosted. See cef_request_context_t::LoadExtension for details.
Retrieve a snapshot of current navigation entries as values sent to the specified visitor. If |current_only| is true (1) only the current navigation entry will be sent, otherwise all navigation entries will be sent.
Retrieve the window handle (if any) of the browser that opened this browser. Will return NULL for non-popup browsers or if this browser is wrapped in a cef_browser_view_t. This function can be used in combination with custom handling of modal windows.
Returns the request context for this browser.
Returns the current visible navigation entry for this browser. This function can only be called on the UI thread.
Retrieve the window handle (if any) for this browser. If this browser is wrapped in a cef_browser_view_t this function should be called on the browser process UI thread and it will return the handle for the top-level native window.
Returns the maximum rate in frames per second (fps) that
Get the current zoom level. This function can only be called on the UI thread.
Returns true (1) if this browser currently has an associated DevTools browser. Must be called on the browser process UI thread.
Returns true (1) if this browser is wrapped in a cef_browser_view_t.
Cancels the existing composition and discards the composition node contents without applying them. See comments on ImeSetComposition for usage. This function is only used when window rendering is disabled.
Completes the existing composition by optionally inserting the specified |text| into the composition node. |replacement_range| is an optional range of the existing text that will be replaced. |relative_cursor_pos| is where the cursor will be positioned relative to the current cursor position. See comments on ImeSetComposition for usage. The |replacement_range| and |relative_cursor_pos| values are only used on OS X. This function is only used when window rendering is disabled.
Completes the existing composition by applying the current composition node contents. If |keep_selection| is false (0) the current selection, if any, will be discarded. See comments on ImeSetComposition for usage. This function is only used when window rendering is disabled.
Begins a new composition or updates the existing composition. Blink has a special node (a composition node) that allows the input function to change text without affecting other DOM nodes. |text| is the optional text that will be inserted into the composition node. |underlines| is an optional set of ranges that will be underlined in the resulting text. |replacement_range| is an optional range of the existing text that will be replaced. |selection_range| is an optional range of the resulting text that will be selected after insertion or replacement. The |replacement_range| value is only used on OS X.
Invalidate the view. The browser will call cef_render_handler_t::OnPaint asynchronously. This function is only used when window rendering is disabled.
Returns true (1) if the browser's audio is muted. This function can only be called on the UI thread.
Returns true (1) if this browser is hosting an extension background script. Background hosts do not have a window and are not displayable. See
Returns true (1) if the renderer is currently in browser fullscreen. This differs from window fullscreen in that browser fullscreen is entered using the JavaScript Fullscreen API and modifies CSS attributes such as the ::backdrop pseudo-element and :fullscreen pseudo-structure. This function can only be called on the UI thread.
Returns true (1) if window rendering is disabled.
Notify the browser that the window hosting it is about to be moved or resized. This function is only used on Windows and Linux.
Send a notification to the browser that the screen info has changed. The browser will then call cef_render_handler_t::GetScreenInfo to update the screen information with the new values. This simulates moving the webview window from one display to another, or changing the properties of the current display. This function is only used when window rendering is disabled.
Print the current browser contents.
Print the current browser contents to the PDF file specified by |path| and execute |callback| on completion. The caller is responsible for deleting |path| when done. For PDF printing to work on Linux you must implement the
If a misspelled word is currently selected in an editable node calling this function will replace it with the specified |word|.
Call to run a file chooser dialog. Only a single file chooser dialog may be pending at any given time. |mode| represents the type of dialog to display. |title| to the title to be used for the dialog and may be NULL to show the default title ("Open" or "Save" depending on the mode). |default_file_path| is the path with optional directory and/or file name component that will be initially selected in the dialog. |accept_filters| are used to restrict the selectable file types and may any combination of (a) valid lower-cased MIME types (e.g. "text/*" or "image/*"), (b) individual file extensions (e.g. ".txt" or ".png"), or (c) combined description and file extension delimited using "|" and ";" (e.g. "Image Types|.png;.gif;.jpg"). |callback| will be executed after the dialog is dismissed or immediately if another dialog is already pending. The dialog will be initiated asynchronously on the UI thread.
Send a capture lost event to the browser.
Send a function call message over the DevTools protocol. |message| must be a UTF8-encoded JSON dictionary that contains "id" (int), "function" (string) and "params" (dictionary, optional) values. See the DevTools protocol documentation at https://chromedevtools.github.io/devtools- protocol/ for details of supported functions and the expected "params" dictionary contents. |message| will be copied if necessary. This function will return true (1) if called on the UI thread and the message was successfully submitted for validation, otherwise false (0). Validation will be applied asynchronously and any messages that fail due to formatting errors or missing parameters may be discarded without notification. Prefer ExecuteDevToolsMethod if a more structured approach to message formatting is desired.
Issue a BeginFrame request to Chromium. Only valid when
Send a key event to the browser.
Send a mouse click event to the browser. The |x| and |y| coordinates are relative to the upper-left corner of the view.
Send a mouse move event to the browser. The |x| and |y| coordinates are relative to the upper-left corner of the view.
Send a mouse wheel event to the browser. The |x| and |y| coordinates are relative to the upper-left corner of the view. The |deltaX| and |deltaY| values represent the movement delta in the X and Y directions respectively. In order to scroll inside select popups with window rendering disabled cef_render_handler_t::GetScreenPoint should be implemented properly.
Send a touch event to the browser for a windowless browser.
Set accessibility state for all frames. |accessibility_state| may be default, enabled or disabled. If |accessibility_state| is STATE_DEFAULT then accessibility will be disabled by default and the state may be further controlled with the "force-renderer-accessibility" and "disable- renderer-accessibility" command-line switches. If |accessibility_state| is STATE_ENABLED then accessibility will be enabled. If |accessibility_state| is STATE_DISABLED then accessibility will be completely disabled.
Set whether the browser's audio is muted.
Enable notifications of auto resize via
Set whether the browser is focused.
Set the maximum rate in frames per second (fps) that
Change the zoom level to the specified value. Specify 0.0 to reset the zoom level to the default. If called on the UI thread the change will be applied immediately. Otherwise, the change will be applied asynchronously on the UI thread.
Open developer tools (DevTools) in its own browser. The DevTools browser will remain associated with this browser. If the DevTools browser is already open then it will be focused, in which case the |windowInfo|, |client| and |settings| parameters will be ignored. If |inspect_element_at| is non-NULL then the element at the specified (x,y) location will be inspected. The |windowInfo| parameter will be ignored if this browser is wrapped in a cef_browser_view_t.
Download the file at |url| using cef_download_handler_t.
Cancel all searches that are currently going on.
Helper for closing a browser. Call this function from the top-level window close handler (if any). Internally this calls CloseBrowser(false (0)) if the close has not yet been initiated. This function returns false (0) while the close is pending and true (1) after the close has completed. See close_browser() and cef_life_span_handler_t::do_close() documentation for additional usage information. This function must be called on the browser process UI thread.
Notify the browser that it has been hidden or shown. Layouting and
Notify the browser that the widget has been resized. The browser will first call cef_render_handler_t::GetViewRect to get the new size and then call cef_render_handler_t::OnPaint asynchronously with the updated regions. This function is only used when window rendering is disabled.
Execute a zoom command in this browser. If called on the UI thread the change will be applied immediately. Otherwise, the change will be applied asynchronously on the UI thread.
Structure used to represent the browser process aspects of a browser. The functions of this structure can only be called in the browser process. They may be called on any thread in that process unless otherwise indicated in the comments.
