I’m playing around with the example “Toolbar buttons”. I’ve removed all items except the play button. How do I get the button to the left side of the toolbar?
You don’t. The toolbar alignment is part of that style.
Now… there is a way to add one or two buttons to the left, but you’ll need declares or other MBS methods to do that.
Just to be clear, what you’ve got there is called a Unified toolbar. That is, it’s combined with the title bar. Any changes you make with this code is only available on macOS 11 and above.
The property I was referring to is called “Navigational”, but it’s really meant for items like Back and Forward, and is applied to the buttons themselves.
Ah, the unified toolbar version is always right aligned.
