ScrollView subclass that lets you insert a view within the scroll bars NSScroller view, for things like zoom controls.

ndcustomizablescrollview

NDCustomizableScrollView is a NSScrollView subclass that lets you insert a view along side the NSScroller of a NSScrollView, for example in a paint or drawing program you could use it to add magnification controls.

Using NDCustomizableScrollView is very simple, use NDCustomizableScrollView in place of NSScrollView and assign your view to be placed to the left of the horizontal NSScroller to the property insertedHorizontalView. This can be done in interface builder, creating your view in interface builder and connecting it to insertedHorizontalView outlet.

NDCustomizableScrollView doesn't make any assumptions about what view you assign/connect to insertedHorizontalView, its up to you to link any controls up to your NSWindowController or NSViewController and do something with that user interaction. For example NDCustomizableScrollView doesn't implement any magnification logic for you, other than what you get from the super class NSScrollView and its super class.

Limitation

Currently NDCustomizableScrollView only supports a single view to the left side of the horizontal NSScroller.

ndcustomizablescrollview's Issues

Insert view in Vertical NSScroller as well.

Just need another property to represent the view.

Switch from left side to right side of scroller.

Could have a bool (or two value enum) to switch between the two sides or alternativly could have a second property for another view so the user could add two views to either side if they want to.

This logic should also work for the vertical scroller as well.
