OSX Quit is not the same as Close

OSX Quit is not the same as Close

[ahlan.marriott]

Hi,

Our applications use GtkAda and catch the main window close-event to shutdown.
Under Windows this works fine but OSX differentiates between closing the main window and quitting the application.
Under OSX closing the main window behaves as expected but using Quit from the docking icon has no effect
From what I understand (which of course is very little) we need to catch the NsApplicationShouldTerminate event - which has nothing to do with Gtk because it has nothing to do with the GUI - an application can be asked to terminate even if it hasn't got a GUI.

But how do I go about catching and processing this signal.
Does anyone know how to do this in Ada?

Best wishes,
Ahlan

Hi Ahlan,
Just wild-guessing: perhaps you need to see how to close the main menu?
On Macs (GUI-wise) the Menu is the boss, even when all windows are closed.
On Windows, the main window is at the top and may contain a menu with a Quit command.

All OSX applications have a menu, the first pulldown of which has the same name as the application and which contains a quit item. Selecting this does nothing. This may well be the same as the Quit in the dock. The question still remains though on how to catch the event generated by selecting this item because my program didn't create it.

I guess that in order to do OSX specific things such as handle the menu quit or find out the filename that started the application (if the application was associated to a file) then I will need to use GtkOsxApplication.

Does anyone know if there are Ada bindings to GtkOsxApplication?
