# SourceView

## Description

"SourceView" demonstrates how to use NSOutlineView backed by NSTreeController and various other Cocoa classes to produce a Finder-like source view.  It also uses NSSplitViewController and a storyboard to organize the various NSViewControllers.

Among the features demonstrated are -

- Source outline view using view-based NSOutlineView

- Loading dictionary data from disk using [NSDictionary dictionaryWithContentsOfFile…] to populate the outline view,

- Outline view uses selection highlight style: NSTableViewSelectionHighlightStyleSourceList, which gives is a gradient-style selection.

- Icon view of directories using NSCollectionView,

- Viewing URLs using WebView,

- Outline view drag and drop support for URLs and file system-based objects (from Safari, Finder, etc),

- Factoring or organizing its various NSViews into NSViewControllers.

- Factoring or organizing its various Windows into NSWindowControllers.

- Obtaining file system icons using NSWorkspace,

- NSSplitView controlled by NSSplitViewController sub-pane size management during divider resize,

- Using template images in our buttons such as NSImageNameAddTemplate and NSImageNameRemoveTemplate
