ColorWell

A color well implementation similar to iWork, inspired by DFColorWell.

All custom drawing is done using layers, the usual NSEvent methods (mouseDown:, mouseUp:) are implemented to keep track of the control's state and turn on/off different drawing options. Colors can only be selected from a predefined set of colors (provided by your data source), unlike DFColorWell.

I initially created this component for my app Ceceree. I ended up using a slightly different version in the final app, but this is still the basis.

Usage

1. Drag an NSView into your XIB or Storyboard
2. Change the class to ColorWell
3. Unlike DFColorWell, ColorWell allows custom sizes, but 67x23 (or similar) looks good
4. Set the color well’s data source and initial selected index path (the latter is not required, but recommended):

    @IBOutlet weak var colorWell: ColorWell! {
        didSet {
            self.colorWell.dataSource = self
            self.colorWell.selectedIndexPath = IndexPath(column: 0, row: 0)
        }
    }

5. Implement all data source methods to populate the popover with cells: ``` func numberOfRowsInColorWell(colorwell: ColorWell) -> UInt func numberOfColumnsInColorWell(colorwell: ColorWell) -> UInt func colorWell(colorwell: ColorWell, colorAtIndexPath indexPath: IndexPath) -> NSColor? ```
