Minimal App

using MewUI; using MewUI.Controls;

var window = new Window() .Title("My App") .Width(800).Height(600) .Content(new Label().Text("Hello, MewUI!"));

Application.Run(window); // Static method

Application Setup

// Set defaults BEFORE Run() Application.DefaultGraphicsBackend = GraphicsBackend.Direct2D; // or Gdi, OpenGL

var window = new Window().Title("My App").Content(mainContent); Application.Run(window);

// Access current app AFTER Run() starts // Application.Current.SetTheme(ThemeVariant.Light);

Common Controls

new Label().Text("Display text").BindText(observable) new TextBox().BindText(observable).Placeholder("Hint") new Button().Content("Click").OnClick(() => DoAction()) new CheckBox().Text("Option").BindIsChecked(observable) // Note: .Text() not .Content() new ComboBox().Items("A", "B", "C").BindSelectedIndex(observable) new ListBox().Items("X", "Y", "Z").BindSelectedIndex(observable) new Slider().Minimum(0).Maximum(100).BindValue(observable) new ProgressBar().Minimum(0).Maximum(100).BindValue(observable) new Image().SourceFile("path.png").StretchMode(ImageStretch.Uniform) // Note: SourceFile, StretchMode

Theming

// Access theme in controls var bg = Theme.Palette.ControlBackground; var accent = Theme.Palette.Accent; // Note: Accent, not AccentColor var radius = Theme.Metrics.ControlCornerRadius;

// Visual states var color = _isPressed ? Theme.Palette.ButtonPressedBackground : IsMouseOver ? Theme.Palette.ButtonHoverBackground : Theme.Palette.ButtonFace;

// Theme change notification - note two parameters protected override void OnThemeChanged(Theme oldTheme, Theme newTheme) { base.OnThemeChanged(oldTheme, newTheme); InvalidateVisual(); }

Fluent Styling

element .Width(200).Height(100) .Margin(8).Padding(4) .Background(Colors.White).Foreground(Colors.Black) .HorizontalAlignment(HorizontalAlignment.Center) .VerticalAlignment(VerticalAlignment.Stretch)

App Layout Pattern

new DockPanel().Children( CreateMenu().DockTo(Dock.Top), // Note: .DockTo() not .Dock() CreateToolbar().DockTop(), // Or convenience methods CreateStatusBar().DockBottom(), CreateSidebar().DockLeft().Width(200), CreateMainContent() // Fills remaining )
