Remarks: This can sometimes be useful to get the platform-specific object. Some handlers may not have any backing object for its functionality, so this may be null. It is more preferred to use the Widget.Handler and cast that to the platform-specific handler class which can give you additional methods and helpers to do common tasks. For example, the Application object's handler for OS X has a AddFullScreenMenuItem property to specify if you want full screen support in your app.

Remarks: When the widget is disposed, it can no longer be used.

Remarks: This gets set to the current Platform.Instance during the construction of the object

Remarks: Styles allow you to attach custom platform-specific logic to a widget. In your platform-specific assembly, use Add{H} to add the style logic with the same id.

// in your UI
var control = new Button { Style = "mystyle" };

// in your platform assembly
using Eto.Mac.Forms.Controls;

Styles.AddHandler<ButtonHandler>("mystyle", handler => {
	// this is where you can use handler.Control to set properties, handle events, etc.
	handler.Control.BezelStyle = NSBezelStyle.SmallSquare;
});

Remarks: The callback should implement the parent class' Widget.ICallback interface so that there only needs to be a single callback for the entire hierarchy. This should return a static instance to avoid having overhead for each instance of your control.

Remarks: This is typically called from the constructor after all of the logic is completed to construct the object. If your handler interface has the AutoInitializeAttribute set to false, then you are responsible for calling this method in your constructor after calling the creation method on your custom handler.
