import UIKit

@IBDesignable
class YearSelectorSegControl: UIView {

    var buttons = [UIButton]()
    var selector: UIView!
    var sv: UIStackView!

    var currentPosition: Int = 0

    @IBInspectable
    var borderWidth: CGFloat = 0 {
        didSet {
            layer.borderWidth = borderWidth
        }
    }

    @IBInspectable
    var borderColor: UIColor = UIColor.clear {
        didSet {
            layer.borderColor = borderColor.cgColor
        }
    }

    @IBInspectable
    var textColor: UIColor = .lightGray {
        didSet {
            updateView()
        }
    }

    @IBInspectable
    var textBackground: UIColor = .clear {
        didSet {
            updateView()
        }
    }

    func updateView() {
        // ... code here ...
    }

    override func draw(_ rect: CGRect) {
        layer.cornerRadius = 0
    }
}
