Inspector Panes for macOS

A Cocoa, auto-layout managed view to build and manage inspector panes equivalent to the inspectors in Apple's Pages and Numbers applications.

Why?

I've implemented and fought with this on a number of different projects and decided to make a drop-in class that would do everything that I wanted. This class is fully autolayout managed.

I really like Apple 'Pages' implementation which allows having a header view which can be used to configure items even when the pane itself is hidden. A good example of this is the 'Spacing' inspector pane, where when the pane is hidden the user can still change the line spacing at a lower granularity.

Expanded	Contracted

Features

• Show and hide panes
• Configurable from interface builder as inspectables
• Optional supply a view as a header view, and set its visibility (always show, show when collapsed)
• Optional automatic scroll view support
• Optional animation
• Optional separators or bounding boxes
• Optional drag/drop reordering of panes
• Show or hide individual panes without removing them
• Expand or contract individual panes

Installation

Direct

Copy the swift files from the DSFInspectorPanes subfolder to your project

CocoaPods

Add the following to your Podfiles file

pod 'DSFInspectorPanes', :git => 'https://github.com/dagronf/DSFInspectorPanes'

API

Create

1. Create an instance of DSFInspectorPanesView and add it to a view, or
2. Use Interface Builder to add a custom view, and change the class to DSFInspectorPanesView

Properties

• animated : Animate the expanding/hiding of the panes
• embeddedInScrollView : Embed the panes view in a scroll view
• showSeparators : Insert a separator between each pane (optional)
• showBoxes : Show a box around each inspector pane (optional)
• titleFont : Specify a custom font to use for the title for the panes
• spacing : Set the vertical spacing between each pane
• canDragRearrange : Allow the user to change the ordering of the panes via drag/drop or touchbar

Methods

Add an inspector pane

Add a new inspector pane to the container

var propertyPanes = DSFInspectorPanesView(
   frame: .zero,
   animated: true,
   embeddedInScrollView: false,
   titleFont: NSFont.systemFont(ofSize: 13)
)

var inspectorView = NSView()        // <--- your inspector pane view
var inspectorHeaderView = NSView()  // <--- your inspector pane header view
	
propertyPanes.addPane(
   title: "My inspector Pane", 
   view: inspectorView,
   headerAccessoryView: inspectorHeaderView,
   expansionType: .expanded)
}

Expand an existing pane

var propertyPanes = DSFInspectorPanesView()
…
propertyPanes.panes[0].expanded = true
propertyPanes.panes[1].expanded = false

Show or hide a pane

var propertyPanes = DSFInspectorPanesView()
…
propertyPanes.panes[0].isHidden = true
propertyPanes.panes[1].isHidden = false

Reordering and moving

Move the property pane at index 0 to index 4

propertyPanes.move(index: 0, to: 4)

Swap property panes at index 0 and index 4

propertyPanes.swap(index: 0, with: 4)

Removing

Remove the pane at index 1

propertyPanes.remove(at: 1)

Remove all panes

propertyPanes.removeAll()
