I am trying to have a complete full screen. No menu bar, no dock.
When I set the window menubar to NONE, and in the app set the menubar to NIL
app.menubar = NIL
In all of the windows, Document and Sheet style, I set it to NONE in the
Menus -> Menu Bar -> NONE
and the File / Edit… etc will go away. But I still see the program menu bar. The same with the Dock.
I have gone through the threads I could find, and people are doing things like calling NSUI… stuff, but I am not that great programmer to use the NS stuff.
the page does not appears in dark mode / I cannot really read it, but as far as I understand, they expose the macOS command to hide the MenuBar and the Dock.
You “only” need to translate it to Xojo Declare.
