If the width is omitted but the height is given ("-geometry x2"), the message window expands over the whole screen (dmenu-like). If width is 0, the window expands to the longest message displayed. A positive x is measured from the left, a negative from the right side of the screen. Y is measured from the top and down respectevly. see also EXAMPLES
