* Everything the desktop does -- wallpaper, icons, layout, selection, drag and

* drop, context menus and file operations -- lives behind this item and reuses
|
|
* the file manager core. A host only has to place the item in a window and tell
|
|
* it which screen it is on:
|
|
*
|
|
* import org.cutefish.filemanager.desktop 1.0

* DesktopView {

* anchors.fill: parent

* primary: true
|
|
* }
|
|
*
|
|
* The item owns no window state (flags, type hints, stacking); that is the
|
|
* host's job, so the same item works on X11, Wayland or inside a test harness.
