Class Scenario

Namespace
UICatalog
Assembly
UICatalog.dll

Base class for each demo/scenario.

To define a new scenario:

  1. Create a new .cs file in the Scenarios directory that derives from Scenario.
  2. Annotate the Scenario derived class with a ScenarioMetadata attribute specifying the scenario's name and description.
  3. Add one or more ScenarioCategory attributes to the class specifying which categories the scenario belongs to. If you don't specify a category the scenario will show up in "_All".
  4. Implement the Main() override which will be called when a user selects the scenario to run.

The UI Catalog program uses reflection to find all scenarios and adds them to the ListViews. Press ENTER to run the selected scenario. Press the default quit key to quit.

Examples

The example below is provided in the Scenarios directory as a generic sample that can be copied and re-named:

using Terminal.Gui;

namespace UICatalog.Scenarios;

[ScenarioMetadata ("Generic", "Generic sample - A template for creating new Scenarios")]
[ScenarioCategory ("Controls")]
public sealed class MyScenario : Scenario
{
    public override void Main ()
    {
        // Init
        Application.Init ();

        // Setup - Create a top-level application window and configure it.
        Window appWindow = new ()
        {
            Title = GetQuitKeyAndName (),
        };

        var button = new Button { X = Pos.Center (), Y = Pos.Center (), Text = "Press me!" };
        button.Accept += (s, e) => MessageBox.ErrorQuery ("Error", "You pressed the button!", "Ok");
        appWindow.Add (button);

        // Run - Start the application.
        Application.Run (appWindow);
        appWindow.Dispose ();

        // Shutdown - Calling Application.Shutdown is required.
        Application.Shutdown ();
    }
}
