14 * This interface controls tab preview-specific behavior. Creating an
15 * nsITaskbarTabPreview for a window will hide that window's
16 * nsITaskbarWindowPreview in the taskbar - the native API performs this
17 * unconditionally. When there are no more tab previews for a window, the
18 * nsITaskbarWindowPreview will automatically become visible again.
20 * An application may have as many tab previews per window as memory allows.
