Instance Method


Sets the size of the view’s bounds rectangle to specified dimensions, inversely scaling its coordinate system relative to its frame rectangle.


func setBoundsSize(_ newSize: NSSize)



An NSSize structure specifying the new width and height of the view's bounds rectangle.


For example, a view object with a frame size of (100.0, 100.0) and a bounds size of (200.0, 100.0) draws half as wide along the x axis. This method neither redisplays the view nor marks it as needing display. Set the needsDisplay property to true when you want the view to be redisplayed.

This method posts an boundsDidChangeNotification to the default notification center if the view is configured to do so.

After calling this method, NSView creates an internal transform (or appends these changes to an existing internal transform) to convert from frame coordinates to bounds coordinates in your view. As long as the width-to-height ratio of the two coordinate systems remains the same, your content appears normal. If the ratios differ, your content may appear skewed.

Sets the origin of the view’s bounds rectangle to a specified point.

var boundsRotation: CGFloat
