Adjusting window title bar look/behavior on El Capitan

Targets macOS
1

Is there any set of Cocoa declares that allow controls to “bleed” over the title bar, like the Contacts app in El Capitan?

In this particular case, I was not planning to use a toolbar; instead, I’d like the controls (ex: a container control) to use the window’s entire height. I’ve been testing this with several window types but the top of the container always gets clipped.

( BTW, If the answer is in a particular issue of xDev, I’ll gladly buy it :smiley: )

declare sub setStyleMask lib “Cocoa” selector “setStyleMask:” (w as integer, s As integer)
declare function styleMask lib “Cocoa” selector “styleMask” (w as integer) As integer

//Yosemite only
declare sub setTitlebarAppearsTransparent lib “Cocoa” selector “setTitlebarAppearsTransparent:” (windowHandle as integer, value as boolean)
setTitlebarAppearsTransparent(self.handle, true)

//add NSFullSizeContentViewWindowMask
setStyleMask(self.Handle, styleMask(self.Handle) or 32768)

  const NSWindowTitleHidden = 1
declare sub setTitleVisibility lib "Cocoa" selector "setTitleVisibility:" (windowHandle as Integer, value as Integer)
setTitleVisibility(self.Handle,NSWindowTitleHidden)

Worked like a charm. Thank you!

I’m using the above code and it is doing just as show above, BUT I’d really like to reposition the traffic light buttons -

My calendar is in front and you can see the close,min,resize buttons are in their normal place which does not align very well with the picker button.

I wonder how to get them a bit down and to the right as in the calendar to the left?

I think @Sam Rowlands has an XDev article on the declares involved with that.
I can’t recall if it’s an entirely different type of window/toolbar or if it’s just a property.

You are correct, I don’t recall what edition it was in, a couple of years ago at least. Basically, you need to use a Toolbar. Which means you need to get your controls into the toolbar and apply almost all of the declares above.

Except this one.
