Screen API window properties are the properties of a window API object.
Screen distinguishes between parent and owner window properties.
Parent window properties are the properties of the window that can be changed by a parent application window or a window manager. A window manager's access to properties is more limited than that of a parent window. A window manager can only change the properties of top-level windows and windows that are created by the window manager itself.
The owner of the window is allowed to set the parent window properties only if the parent window has set its SCREEN_PROPERTY_SELF_LAYOUT property to true, or when there is no parent window or window manager present.
Owner window properties are properties that can be changed by the owner of the window; some owner window properties can be changed by both the owner and the parent of the window.
The following table lists all of the window properties and indicates whether each can be changed by the parent window, the window manager or the window owner:
