The set of bar common properties includes:
A bar does not have a title .
A bar does not have a value.
The SIZE and LINES values of a bar are measured in window cells. One of the SIZE or LINES phrases must be zero (or unspecified). If LINES is zero, the bar is horizontal. If SIZE is zero, the bar is vertical. Setting SIZE and LINES to non-zero values has an undefined effect.
A bar uses only the foreground color. The foreground color is the color of the entire bar. See the COLORS special property for other options.
A bar does not have styles in a character-based operating system. In a graphical system, a bar can have the following styles:
| DOTTED | This style creates a dotted line instead of a solid line. It is a valid style only when the bar's width is one. The COLORS and SHADING properties are ignored when this style is specified. The line is drawn with the control's foreground color. This style is not available on character-based systems. |
| DASHED | This style creates a dashed line instead of a solid line. It is valid only when the bar's width is one. The COLORS and SHADING properties are ignored when this style is specified. The line is drawn with the control's foreground color. This style is not available on character-based systems. |
| DOT-DASH | This style creates a line that alternates dots and dashes. It is valid only when the bar's width is one. The COLORS and SHADING properties are ignored when this style is specified. The line is drawn with the control's foreground color. This style is not available on character-based systems. |
