fs28 An NSSplitView object lets several views share a region within a window. The NSSplitView resizes its subviews so that each subview is the same width as the NSSplitView, and the total of the subviews'27 heights is equal to the height of the NSSplitView. The NSSplitView positions its subviews so that the first subview is at the top of the NSSplitView, and each successive subview is positioned below the previous one. The user can set the height of two subviews by moving a horizontal bar called the i divideri0 , which makes one subview smaller and the other larger.

fs28 To add a view to an NSSplitView, you use the NSView methodb addSubview:b0 . When the NSSplitView is displayed, it checks to see if its subviews are properly tiled. If not, it invokes the delegate methodb splitView:resizeSubviewsWithOldSize:b0 , allowing the delegate to specify the heights of specific subviews. If the delegate doesn'27t implement this method,b b0 the NSSplitViewb b0 sendsb adjustSubviewsb0 to itself to yield the default tiling behavior.

fs28 When a mouse-down occurs in an NSSplitView'27s divider, the NSSplitView determines the limits of the divider'27s travel and tracks the mouse to allow the user to drag the divider within these limits. With the following mouse-up, the NSSplitView resizes the two affected subviews, informs the delegate that the subviews were resized, and displays the affected views and divider. The NSSplitView'27s delegate can constrain the travel of specific dividers by implementing the method b splitView:constrainMinCoordinate:maxCoordinate:ofSubviewAt:b0 .
