Majorsilence.Forms.Headless

An offscreen platform backend for Majorsilence.Forms: renders real frames and processes real input with no display, no window manager, and no windowing toolkit — just SkiaSharp.

Use it to unit-test UI logic, snapshot-render forms in CI, or generate images on a server.

Install

dotnet add package Majorsilence.Forms
dotnet add package Majorsilence.Forms.Headless

Unlike the desktop backend, this one is selected explicitly. HeadlessRenderer.Use() does it:

using Majorsilence.Forms;
using Majorsilence.Forms.Headless;

HeadlessRenderer.Use ();

Render a form to a PNG

HeadlessRenderer.Use ();

var form = new MainForm ();
HeadlessRenderer.CapturePng (form, 800, 600);          // first call lays out
var png = HeadlessRenderer.CapturePng (form, 800, 600);

File.WriteAllBytes ("form.png", png);

The first capture performs the layout pass, so capture twice when you need the settled frame.

Drive input in a test

HeadlessRenderer.Use ();

var clicks = 0;
var button = new Button { Text = "Click", Left = 20, Top = 20, Width = 120, Height = 40 };
button.Click += (_, _) => clicks++;

var form = new Form ();
form.Controls.Add (button);

HeadlessRenderer.CapturePng (form, 300, 200);   // force a layout pass
HeadlessRenderer.Click (form, 80, 40);          // center of the button

Assert.Equal (1, clicks);

Available: CapturePng, Click, MouseDown, MouseUp, MouseMove, KeyDown, KeyUp, TextInput. The keyboard methods return the framework's "handled" flag.

Why it exists

Beyond testing, this is the reference second backend. Because it shares no code with the Avalonia or Uno backends, anything that works here is genuinely going through the neutral IPlatformBackend/IWindowBackend seam rather than leaning on a specific toolkit — which is what keeps the same app able to target Avalonia today and Uno tomorrow.
