The orientation of the panel. Possible values are "top", "bottom", "left", "right". In expanded mode the key specifies which screen edge the panel is on. In un-expanded mode the difference between "top" and "bottom" is less important - both indicate that this is a horizontal panel - but still give a useful hint as to how some panel objects should behave. For example, on a "top" panel a menu button will pop up its menu below the panel, whereas on a "bottom" panel the menu will be popped up above the panel.
Panelaren orientazioa. Hauek dira balio posibleak: "top" (goian), "bottom" (behean), "left" (ezkerrean), "right" (eskuinean). Panela zabalduta dagoenean zein pantaila-ertzetan kokatuko den zehazten du. Zabalduta ez dagoenean, "top" eta "bottom" ezarpenek panela horizontala dela adierazten dute, baina ez dute berdin-berdin jokatzen paneleko objektu batzuekin. Adibidez, "top" bada, menu-botoi bat sakatutakoan panelaren azpian azalduko da menua, eta alderantziz, "bottom" bada, gainean agertuko da.
