Constants

Gestalt Selector and Response Values

You can pass the gestaltQuickDraw3DViewer selector to the Gestalt function to determine information about the availability of the 3D Viewer.

enum {
   gestaltQuickDraw3DViewer         = 'q3vc'
}

Gestalt returns information to you by returning a long word in the response parameter. Currently, the returned values are defined by constants:

enum {
   gestaltQ3ViewerNotAvailable      = 0,
   gestaltQ3ViewerAvailable         = 1
}
