About Fixing the Spacing Around a Boxed Row or Column (DCL)

If the label attribute of a boxed row or column is either blank ( " " ) or null ( "" ), the box encloses the cluster but no text is shown.

Note: DCL support in AutoLISP is limited to Windows only.

A single blank does not appear as a space in the box. However, there is a difference in the way blank and null labels are laid out:

In the following DCL code, the top lines of the boxes around the first two columns are guaranteed to line up (with the same Y location), and the top line of the box around the third column is guaranteed to have no spacing above or below it, except for the default margins:

: row {
  : boxed_column {
    label = "Some Text";
  }
  : boxed_column {
    label = " ";         // single blank: the default
  }
  : boxed_column {
    label = "";          // null string
  }
}
