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.
Die oriëntering van die paneel. Moontlike waardes is "bokant", "onderkant", "links", "regs". In uitgevou-modus spesifiseer die sleutel aan watter skermkant die paneel is. In onuitgevou-modus is die verskil tussen "bokant" en "onderkant" 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 "bokant"-paneel sal die kieslysknoppie byvoorbeeld onder die paneel uitspring, maar op 'n "onderkant"-paneel sal die kieslys bokant die paneel uitspring.
