Specifies the width of the control. If this attribute is undefined the width will be determined by the size of the parent bar. If the bar is aligned left or right the width of the control will be equal to the bar's size minus twice its padding. If the bar is aligned top or bottom the width will be proportional to the height, so as to maintain the same aspect ratio as the control's skin graphic.

If this attribute is defined and the height attribute is not, the control's height will be adjusted to maintain the same aspect ratio as the skin graphic only if the parent bar is left or right aligned. Otherwise the height will not be adjusted and the skin graphic will be scaled non-proportionally.

Non-numeric string values for the width attribute are only valid if the parent bar is aligned top or bottom. They indicate that the control's width should be based on the available space remaining in the bar, after the other controls and bar spacing are taken into account. If two or more controls have string values, the available space is divided amongst them based on the relative lengths of the strings. For instance if there are only two controls in a bar and the first has a width of '*' while the second has a width of '**', the first will occupy one third of the bar while the second occupies the other two thirds.
