## Detailed Description

You can create a custom window background by replacing the "background" delegate of ApplicationWindowStyle with a custom design.

Example:

     ApplicationWindow {
         style: ApplicationWindowStyle {
             background: BorderImage {
                 source: "background.png"
                 border { left: 20; top: 20; right: 20; bottom: 20 }
             }
         }
     }

## Property Documentation

background : Component

A custom background for the window.

Note: The window might have a custom background color set. The custom background color is automatically filled by the window. The background delegate should respect the custom background color by either hiding itself altogether when a custom background color is set, or by letting the custom background color shine through.

The following read-only property is available within the scope of the background delegate:

styleData.hasColor : bool | Whether the window has a custom background color set.

[read-only] control : ApplicationWindow

The window attached to this style.
