Description

The class cocoa-default-application-interface supports application messages and the application menu for a Cocoa application.

When non- nil , message-callback should be a function with signature

interface message &rest args

message-callback will be called for various application messages. The interface argument will be the application interface and the message argument will be a keyword. The only currently defined message is :open-file . In this case args will contain the name of the file to open. This message is invoked when the user double-clicks on a document associated with the application or drags a document into the application icon.

application-menu controls the application's main menu. If this is nil , then a minimal application menu will be made using the title of the application interface, otherwise it should be a menu containing the usual items or the name of a slot containing such a menu in the application interface.

interface initargs are interpreted as follows:

• The activate-callback is called when the application is activated or deactivated.
• The destroy-callback is called when the application shuts down.
• The confirm-destroy-function is called to confirm whether the application should shut down.

The application interface also allows you to control aspects of the application. In particular:

• The function destroy will cause the application to shut down.
• The function top-level-interface-display-state will return :hidden if the whole application is hidden and will return :normal otherwise.
• The function (setf top-level-interface-display-state) can be used to perform some operations typically found on the application menu.

The display-state value can one of:

:normal

Show the application and activate it

:restore

Show the application again without activating it

:hidden

Hide

:others-hidden

Hide Others

: all-normal

Show All

To make your application use your cocoa-default-application-interface , do not display it explicitly, but call set-application-interface.

Note: cocoa-default-application-interface is implemented only in LispWorks for Macintosh with the Cocoa IDE.
