方法详细资料

onBeforeContextMenu

void onBeforeContextMenu(CefBrowser browser,
                         CefFrame frame,
                         CefContextMenuParams params,
                         CefMenuModel model)

Called before a context menu is displayed.

在显示上下文菜单之前调用

参数:

browser - The corresponding browser. 相应的浏览器

frame - The corresponding frame. 相应的框架

params - provides information about the context menu state. 提供有关上下文菜单状态的信息

model - can be cleared to show no context menu or modified to show a custom menu. 可以清除以显示上下文菜单或修改为显示自定义菜单

onContextMenuCommand

boolean onContextMenuCommand(CefBrowser browser,
                             CefFrame frame,
                             CefContextMenuParams params,
                             int commandId,
                             int eventFlags)

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

被调用以执行从上下文菜单中选择的命令。 如果处理了命令，则返回true;对于默认实现，返回false。 有关具有默认实现的命令ID，请参阅cef_menu_id_t。 所有用户定义的命令ID都应在MENU_ID_USER_FIRST和之间

参数:

browser - The corresponding browser. 相应的浏览器

frame - The corresponding frame. 相应的框架

params - Will have the same values as what was passed to onBeforeContextMenu(). 将具有与传递给onBeforeContextMenu（）的值相同的值

commandId - The id of the command. 命令的id

eventFlags - A combination of event flags defined in EventFlags EventFlags中定义的事件标志的组合

返回:

true if the command was handled or false for the default implementation. 如果处理了命令，则为true;对于默认实现，则为false

onContextMenuDismissed

void onContextMenuDismissed(CefBrowser browser,
                            CefFrame frame)

Called when the context menu is dismissed irregardless of whether the menu was empty or a command was selected.

无论菜单是空还是选择了命令，都会在关闭上下文菜单时调用

参数:
