Use combined titlebar + toolbar while preserving t

问题:

The System Preferences app feature a combined title bar and toolbar with vertically centered buttons and the title. I am trying to mimic this exactly in my app. I have been able to combine the title bar and toolbar using Interface Builder (on the NSWindow check Title Bar and Unified Title and Toolbar), but this does not center the content vertically. I discovered via this question you can simply set the window's titleVisibility to NSWindowTitleHidden which will vertically center the stoplight buttons. Unfortunately this of course hides the title. How can one vertically center content in the unified titlebar/toolbar and also show the window's title just like System Preferences - either in IB or programmatically?

回答1:

I ended up setting titleVisibility to NSWindowTitleHidden and manually created an NSView that contains an NSTextField that mimics the standard title appearance, providing that to the window's addTitlebarAccessoryViewController method. Still would like to find a better solution to use the default title appearance, if possible.

I used WAYAppStoreWindow on GitHub to do this. I created a fork of the WAYWindow subproject to vertically centre the document title since this wasn't supported. This means any applied themes/appearances are honoured.
