ColorPicker

ColorPicker is an input control used to select a XenoAtom.Terminal.UI.Color (RGB or RGBA).

ColorPicker{.terminal}

Usage

var color = new State<Color>(Color.RgbA(0x50, 0x9A, 0xF6, 0x88));

var picker = new ColorPicker()
    .AllowAlpha(true)
    .ShowPalette(true)
    .Value(color);

The UI includes:

  • RGB sliders (and an optional Alpha slider)
  • Hex input (#RRGGBB or #RRGGBBAA when alpha is enabled)
  • An optional palette derived from the current Theme.Scheme (or an explicit Palette)

Palette

Use Palette to override the swatches displayed by the picker:

var picker = new ColorPicker()
    .Palette(
        Color.Rgb(0xF7, 0x5B, 0x72),
        Color.Rgb(0x67, 0xAF, 0x34),
        Color.Rgb(0x50, 0x9A, 0xF6));

null entries in the palette are treated as Color.Default.

Defaults

  • Default alignment: HorizontalAlignment = Align.Stretch, VerticalAlignment = Align.Start

Styling

ColorPicker is styled through ColorPickerStyle:

picker.Style(new ColorPickerStyle
{
    SwatchWidth = 18,
    SwatchHeight = 9,
    PaletteColumns = 10,
});
