Nevermind, found the answer:
float ToolbarHeightForWindow(NSWindow *window)
{
NSToolbar *toolbar;
float toolbarHeight = 0.0;
NSRect windowFrame;
toolbar = [window toolbar];
if(toolbar && [toolbar isVisible])
{
windowFrame = [NSWindow contentRectForFrameRect:[window frame]
styleMask:[window styleMask]];
toolbarHeight = NSHeight(windowFrame)
- NSHeight([[window contentView] frame]);
}
return toolbarHeight;
}
