Druid: Figure out how dictation/emoji menu items work

[cmyr]

Not sure whether it fits here, but on Mac the "Quit" entry should be last. While on Mac Rundender it is the 3rd last.

Thanks. As noted in the referenced thread, the last two entries should be under the Edit menu.

I can reproduce. These two items are dynamically added to our menu by AppKit, and they're putting them in the wrong place; I really don't know much more than that at the moment.

Druid's "quit" example shows this behaviour already (while slightly different):

• https://stackoverflow.com/a/30046514 explains how to prevent those menu entries at all
• https://stackoverflow.com/a/21370654 says that those entries are present in applicationDidFinishLaunching: or later. applicationWillFinishLaunching: would be too early

There are quite a few gotcha’s to adding things to the global menu.
First is that every NSMenuItem and NSMenu you add needs to have the title property set,
otherwise they won’t be visible.

So if i do both:

let () = msg_send![menu.menu, setTitle: menu_item_title];
let () = msg_send![menu_item, setTitle: menu_item_title];

then it does not look too bad (i've added an empty "Edit" menu myself):

Notice that "Start Dictation ..." is missing, so this solution is not yet perfect.

And as a bonus, if you add an empty "View" menu, there are more automagical entries:

For reference, here is how Cacao does it:

• https://github.com/ryanmcgrath/cacao/blob/trunk/src/macos/menu/menu.rs
• https://github.com/ryanmcgrath/cacao/blob/trunk/src/macos/menu/item.rs

The difference is that Druid's Menu does not have a title.

@cmyr : Oh, you've removed the setting of the menu time title in https://github.com/linebender/druid/commit/e47b335709f17357f79e2232980d713e2a08d56c

Do you remember why?

[cmyr]

I don't remember exactly, except that I remember there being some weirdness when the top-level menu (which is basically the menubar itself?) had a name? But I did not research this is thoroughly as you are doing.

[kud1ing]

In this case, maybe one could just disable that for the main menu, by comparing the menu with NSApplication:: mainMenu().
