PopoverWrapper Example

This example demonstrates how to use PopoverWrapper<TView> to make any View into a popover without implementing the IPopover interface.

Overview

PopoverWrapper<TView> is similar to RunnableWrapper<TView, TResult> but for popovers instead of runnables. It wraps any View and automatically handles:

Setting proper viewport settings (transparent, transparent mouse)
Configuring focus behavior
Handling the quit command to hide the popover
Sizing to fill the screen by default

Key Features

Fluent API: Use .AsPopover() extension method for a clean, fluent syntax
Any View: Wrap any existing View - Button, ListView, custom Views, forms, etc.
Automatic Management: The wrapper handles all the popover boilerplate
Type-Safe: Generic type parameter ensures type safety when accessing the wrapped view

Usage

Basic Usage

// Create any view
var myView = new View
{
    X = Pos.Center (),
    Y = Pos.Center (),
    Width = 40,
    Height = 10,
    BorderStyle = LineStyle.Single
};

// Wrap it as a popover
PopoverWrapper<View> popover = myView.AsPopover ();

// Register and show
app.Popover.Register (popover);
app.Popover.Show (popover);

With ListView

var listView = new ListView
{
    Title = "Select an Item",
    X = Pos.Center (),
    Y = Pos.Center (),
    Width = 30,
    Height = 10,
    Source = new ListWrapper<string> (["Apple", "Banana", "Cherry"])
};

PopoverWrapper<ListView> popover = listView.AsPopover ();
app.Popover.Register (popover);
app.Popover.Show (popover);

With Custom Forms

View CreateFormView ()
{
    var form = new View
    {
        Title = "User Form",
        X = Pos.Center (),
        Y = Pos.Center (),
        Width = 60,
        Height = 16
    };
    
    // Add form fields...
    
    return form;
}

View formView = CreateFormView ();
PopoverWrapper<View> popover = formView.AsPopover ();
app.Popover.Register (popover);
app.Popover.Show (popover);

Comparison with RunnableWrapper

Feature	RunnableWrapper	PopoverWrapper
Purpose	Make any View runnable as a modal session	Make any View into a popover
Blocking	Yes, blocks until stopped	No, non-blocking overlay
Result Extraction	Yes, via typed Result property	N/A (access WrappedView directly)
Dismissal	Via RequestStop() or Quit command	Via Quit command or clicking outside
Focus	Takes exclusive focus	Shares focus with underlying content
