Member Function Documentation
◆ OnBeforeContextMenu()
|
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()
|
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()
|
inlinevirtual |
Called when the context menu is dismissed irregardless of whether the menu was canceled or a command was selected.
◆ OnQuickMenuCommand()
|
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()
|
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()
|
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()
|
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.
