These procedure parses the string and fills in the result in the
Tk_Dash structure. The string can be a list of integers or a
-character string containing only \fB[.,-_]\fR or spaces. If all
-goes well, \fBTCL_OK\fR is returned. If \fIstring\fR doesn't have the
+character string containing only
+.QW \fB.,\-_\fR
+or spaces. If all
+goes well, \fBTCL_OK\fR is returned. If \fIstring\fR does not have the
proper syntax then \fBTCL_ERROR\fR is returned, an error message is left
in the interpreter's result, and nothing is stored at *\fIdashPtr\fR.

The first possible syntax is a list of integers. Each element
represents the number of pixels of a line segment. Only the odd
-segments are drawn using the "outline" color. The other segments

The main difference of this syntax with the previous is that it
is shape-conserving. This means that all values in the dash
list will be multiplied by the line width before display. This
