SwiftUI and NSFontPanel/NSFontManager

Forums > SwiftUI

I am trying to get NSFontPanel working with SwiftUI using a Document Lifecyle template.

I can get the panel and font, style and size selection working.

Interesting, there is a color picker in the panel, which is not mentioned in any documentation I can find.

I would like to either be able to let the use select a color, and then use it to set the color for my font, in the Label in the sidebar, or if I can't get it to work, I would prefer the color picker not show in the font panel.

Any suggestions would be greatly appreciated.

public struct FontPicker: View{

    let labelString: String

    @Binding var font: NSFont
    @State var fontPickerDelegate: FontPickerDelegate?

    public init(_ label: String, selection: Binding<NSFont>) {
        self.labelString = label
        self._font = selection
    }

    let fontManager = NSFontManager.shared
    let fontPanel = NSFontPanel.shared

    @AppStorage("setSidebarFont") var setSidebarFont = "System"
    @AppStorage("setSidebarFontSize") var setSidebarFontSize = 24
    @AppStorage("setSidebarFontColor") var setSidebarFontColor = "gray"

    public var body: some View {

        HStack {

            Text(labelString)

            Button {

                if fontPanel.isVisible {
                    fontPanel.orderOut(nil)
                    return
                }

                self.fontPickerDelegate = FontPickerDelegate(self)
                fontManager.target = self.fontPickerDelegate
                fontManager.action = #selector(fontPickerDelegate?.changeAttributes)

                fontPanel.setPanelFont(self.font, isMultiple: false)
                fontPanel.orderBack(nil)

            } label: {

                Text("Font Selection: \(setSidebarFont)")
                    .font(.custom(setSidebarFont, size: CGFloat(setSidebarFontSize)))
            }
        }
    }

    func fontSelected() {

        self.font = fontPanel.convert(self.font)
        setSidebarFont = self.font.displayName ?? "System"
        setSidebarFontSize = Int(self.font.pointSize)

        var newAttributes = fontManager.convertAttributes([String : AnyObject]())

        newAttributes["NSForegroundColorAttributeName"] = newAttributes["NSColor"]
        newAttributes["NSUnderlineStyleAttributeName"] = newAttributes["NSUnderline"]
        newAttributes["NSStrikethroughStyleAttributeName"] = newAttributes["NSStrikethrough"]
        newAttributes["NSUnderlineColorAttributeName"] = newAttributes["NSUnderlineColor"]
        newAttributes["NSStrikethroughColorAttributeName"] = newAttributes["NSStrikethroughColor"]
        print("\(newAttributes["NSForegroundColorAttributeName"]!)")
    }
}
