Die oriëntering van die paneel. Moontlike waardes is "top", "bottom", "left", "right". In uitgevou-modus spesifiseer die sleutel aan watter skermkant die paneel is. In onuitgevou-modus is die verskil tussen "top" en "bottom" minder belangrik - beide dui aan dat hierdie 'n horisontale paneel is - maar dit gee nogtans 'n nuttige wenk oor hoe sommige paneelobjekte hulle moet gedra. Op 'n "top"-paneel sal die kieslysknoppie byvoorbeeld onder die paneel uitspring, maar op 'n "bottom"-paneel sal die kieslys bokant die paneel uitspring.
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.
