NSVisualEffectViewMBS class

Super class: NSViewMBS

Type Topic Plugin Version macOS Windows Linux Console & Web iOS
class Cocoa MBS MacFrameworks Plugin 14.3 Yes No No Yes, macOS only No
Function: The class to use visual effect view.
The NSVisualEffectView is the basis for all visual effects, including "vibrant" appearances. You can optionally set the appearance to NSAppearanceMBS.appearanceNamed(NSAppearanceNameVibrantDark) (or Light) to get the desired light or dark appearance. Combine this with an appropriate light or dark material to get the desired vibrant look. Combining NSAppearanceNameVibrantDark with a light material will look bad, and should not be done.

Requires Mac OS X 10.10 or newer.

Please review Apple's documentation on this for details.
Subclass of the NSViewMBS class.
