The methods of this class will be called on the UI thread. Called before a context menu is displayed. |params| provides information about the context menu state. |model| initially contains the default context menu.

Called to allow custom display of the context menu. |params| provides information about the context menu state. |model| contains the context menu model resulting from OnBeforeContextMenu.

Do not keep references to |params| or |model| outside of this callback. Called to execute a command selected from the context menu. Return true if the command was handled or false for the default implementation. See cef_menu_id_t for the command ids that have default implementations. All user-defined command ids should be between MENU_ID_USER_FIRST and MENU_ID_USER_LAST. |params| will have the same values as what was passed to OnBeforeContextMenu(). Do not keep a reference to |params| outside of this callback. Called when the context menu is dismissed irregardless of whether the menu was canceled or a command was selected.

Return true if the menu will be handled and execute |callback| either synchronously or asynchronously with the selected command ID. Return false to cancel the menu. Called to execute a command selected from the quick menu for a windowless browser. Return true if the command was handled or false for the default implementation. See cef_menu_id_t for command IDs that have default implementations. Called when the quick menu for a windowless browser is dismissed irregardless of whether the menu was canceled or a command was selected. Provides information about the context menu state. The methods of this class can only be accessed on browser process the UI thread. Returns the X coordinate of the mouse where the context menu was invoked. Coords are relative to the associated RenderView's origin. Returns the Y coordinate of the mouse where the context menu was invoked. Coords are relative to the associated RenderView's origin. Returns flags representing the type of node that the context menu was invoked on. Returns the URL of the link, if any, that encloses the node that the context menu was invoked on. Returns the link URL, if any, to be used ONLY for "copy link address". We don't validate this field in the frontend process. Returns the source URL, if any, for the element that the context menu was invoked on. Example of elements with source URLs are img, audio, and video. Returns true if the context menu was invoked on an image which has non-empty contents. Returns the title text or the alt text if the context menu was invoked on an image. Returns the URL of the top level page that the context menu was invoked on. Returns the URL of the subframe that the context menu was invoked on.

Returns true if the context menu was invoked on an editable node where spell-check is enabled. Returns flags representing the actions supported by the editable node, if any, that the context menu was invoked on. Returns true if the context menu contains items specified by the renderer process.
