Detailed Description

Implement this interface to handle context menu events.

The methods of this class will be called on the UI thread.

Member Typedef Documentation

Member Function Documentation

◆ OnBeforeContextMenu()

virtual void CefContextMenuHandler::OnBeforeContextMenu ( CefRefPtr< CefBrowser browser,
CefRefPtr< CefFrame frame,
CefRefPtr< CefContextMenuParams params,
CefRefPtr< CefMenuModel model 
)
inlinevirtual

Called before a context menu is displayed.

|params| provides information about the context menu state. |model| initially contains the default context menu. The |model| can be cleared to show no context menu or modified to show a custom menu. Do not keep references to |params| or |model| outside of this callback.

◆ OnContextMenuCommand()

virtual bool CefContextMenuHandler::OnContextMenuCommand ( CefRefPtr< CefBrowser browser,
CefRefPtr< CefFrame frame,
CefRefPtr< CefContextMenuParams params,
int  command_id,
EventFlags  event_flags 
)
inlinevirtual

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.

◆ OnContextMenuDismissed()

virtual void CefContextMenuHandler::OnContextMenuDismissed ( CefRefPtr< CefBrowser browser,
CefRefPtr< CefFrame frame 
)
inlinevirtual

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

◆ OnQuickMenuCommand()

virtual bool CefContextMenuHandler::OnQuickMenuCommand ( CefRefPtr< CefBrowser browser,
CefRefPtr< CefFrame frame,
int  command_id,
EventFlags  event_flags 
)
inlinevirtual

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.

◆ OnQuickMenuDismissed()

virtual void CefContextMenuHandler::OnQuickMenuDismissed ( CefRefPtr< CefBrowser browser,
CefRefPtr< CefFrame frame 
)
inlinevirtual

Called when the quick menu for a windowless browser is dismissed irregardless of whether the menu was canceled or a command was selected.

◆ RunContextMenu()

virtual bool CefContextMenuHandler::RunContextMenu ( CefRefPtr< CefBrowser browser,
CefRefPtr< CefFrame frame,
CefRefPtr< CefContextMenuParams params,
CefRefPtr< CefMenuModel model,
CefRefPtr< CefRunContextMenuCallback callback 
)
inlinevirtual

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. For custom display return true and execute |callback| either synchronously or asynchronously with the selected command ID. For default display return false. Do not keep references to |params| or |model| outside of this callback.

◆ RunQuickMenu()

virtual bool CefContextMenuHandler::RunQuickMenu ( CefRefPtr< CefBrowser browser,
CefRefPtr< CefFrame frame,
const CefPoint location,
const CefSize size,
QuickMenuEditStateFlags  edit_state_flags,
CefRefPtr< CefRunQuickMenuCallback callback 
)
inlinevirtual

Called to allow custom display of the quick menu for a windowless browser.

|location| is the top left corner of the selected region. |size| is the size of the selected region. |edit_state_flags| is a combination of flags that represent the state of the quick menu. 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.
