## Browser windows

This section is a reference to all the widgets used in a browser top level window. The following picture shows such a window and how the widgets listed here are packed: the top level window beign a #BrowserWindow in which some #BrowserPerspective widgets are packed (along with a menubar and a statusbar). Each #BrowserPerspective widget packs some specific widgets and optionally some #BrowserPage widgets. The #BrowserPerspective and #BrowserPage are interfaces so no limitation is imposed on the widgets implementing them.
